Just as it says... Took the car around the block. Couldn't go far expired tags, and open pipes ( asking for trouble) but so far so good thanks to all that have helped along the way.
Thanks I want to drive it up town this Saturday to a local exhaust shop and get an estimate. Hoping they are not going to r*pe me on this. Is $500 realistic for a custom exhaust? Has quite a rumble right now LOL.

Sweet. what clutch are you running? is it a stock LS1 manifold? I would think $500 is kinda high if you just come straight from the manifold to the tip(like archie's kit)

Yeah, a "cumulative information session" would be nice. You know, things like what all you've done to handle the power (suspension, tires, etc.), what you went through to get it in there (engine/tranny mounts, accessory mounting, etc.), and what you're choice of grenade...er...transmission is.
Cool deal, we all look forward to seeing more of this setup!

More info huh... Lets see don't exactly know where to start.... When I started this I wanted a fuel injected engine. An LS1 wasn't my first choice, but I came across one cheap while I was looking for an LT1 or L98. I also wanted rubber mounts accomplished! AC didn't happen maybe in the future. I ended up using stock axles, but with one tripot joint being a type 1 instead of a type 3. The starter was a pitta. Had to make a custom mount, and drive gear. Flywheel is for a c5 with an aluminum spacer to get the right back set. I am using a kevlar clutch made by ram (only time will tell how long it holds up). I want to use the power master I keep hearing about. Wish I would have heard of it sooner. I am using the stock getrag 282 I don't plan on beating it so it should work fine. The engine does not have to be moved over apposed to popular belief. It fits just fine when you use an electric water pump, and c5 under drive pulley I did have to make a small notch in the frame but nothing compared to others I have seen ( not knocking anyone just couldn't bring myself to do that much cutting on my GT, and I have no basis to argue it just a gut feeling). I had to make a custom manifold for the forward side( starter conflict). And used a spacer on the aft LS6 one so I could move my stock engine mount up about an inch for more clearance on the axle( fortunately GM already makes this and only $17 a side). The mount in my web site is not the final one. First draft LOL. There was allot of that. I put things together and then saw how they could be better. Had to modify the cradle for oil pan clearance, but able to leave stock filter in place. I am using a Pace modified LS6 MAF/IAT. Stock PCM at this point but want to have custom programing done. I modified the harness myself including making a VATS module. Got the bolt patterns from chevy power book. Drew the CAD drawings myself, and had a CNC shop drill the holes for the adapter plate ( that was amazingly cheap too $50). Through out this hole thing I have found that if you go in and talk to people and tell the, what you are doing they treat you fair. All in all I would say I spent less than $4,000. So far I am using the stock suspension. I want to get better ones , but for this fall I think I will just drive it and enjoy it, and work on that this winter. I see no reason I couldn't bring it to fieroramma. Like I said I have only took it around the block so far. Haven't even had it up to temperature yet. So barring no problems yes LOL

I hope you can make it to Fierorama too- I'd love to see that in person! Awsome work... feel free to post more pics when you get around to it. BTW: what does the rest of the car look like?
Thanks! .... don't know about ultimate car though. not knocking the Fiero , but would trade it for a viper any day the 02 WS6 are pretty cool too what is your user name on ls1.com? (mine is the same) . Haven't said anything over there yet. Don't want to come across like that mini van last year LOL. the rest of the car is a stock 87 GT medium red metallic, with T-tops. If it ever stops raining around here I will take a shot of the whole car with the decklid open. If I do get to take to fieroramma please come up and introduce your selves. I don't want to make any promises just yet. Because like I said I just had it out once so far, so I don't know what problems I may incur, but I just couldn't keep quiet about it LOL. I actually ran it for the first time Sunday, but kept my mouth shut until I could take it for a test drive.

Quite a sleeper then? I like that! I hope you do make it to Fierorama... I'll definitely introduce myself (and probably drool on your engine swap... but it cleans up easily ). I'm sure your 1st startup on Sunday was quite the adrenaline rush!

you flip-flopped the intake manifold. How hard was that? Once you can drive it around for a few months and if everything tests out OK, MAKE A KIT! You could make a killing if priced right

Good eye... I almost forgot about that. It is easy on the LS1. The intake is dry (no coolant running through), and it does not serve as the valley cover. The only parts it contacts are the heads. Which are symmetrical. The harness has to remain in its original orientation though. So I needed to lengthen the wires to manifold pressure sensor, and pull back the ones that go to the throttle body. I would be willing to help anyone interested, and give them all the info I have. I do have a friend and coworker that wants one so maybe one but beyond that I don't think so. I have been corresponding back and forth with one other member working on one for a Fiero, but he has chosen to keep quiet about it so I will respect that. Maybe he will want to fill that demand. Hear is a better picture but still an old one. I need to take more but have been busy with other stuff... Oh and the clutch I was wanting is a quarter master not powermaster...my bad

LS1swap- My user name is the same over at LS1.com- RRobinson. I usually hang out in the WS6-Firehawk area. I agree- Vipers are great-as are Z06 Corvettes, but a Red/Beechwood leather 88 GT T-Top with LS1 power is the true ultimate car.

How's the access around the engine for maintenance? Access to spark plugs, belt driven accessories, and the serpentine belt? I wonder how it would compare to either a Northstar or regular SBC for maintenance.
You said you didn't have to move the engine to the side? If so, this may be a really great swap. Factory location (no special axles needed), all aluminum engine, 320+ HP stock, and no problems with water pump clearance.
How bad was the wiring? I know GM sells LS1 crate motors with ECM for non-computerized cars. If you can get that harness/ECM, that would probably make the swap much easier.

Thanks! I do like the 86-88 GT's 88 being the best. I do want to get Mr. Mikes leather seats, but I want the two tone gray to match my current interior.
Access is pretty tight , but so was my V6. The front plugs will have to be changed from underneath, but the stock plugs are AC fine wire plugs so they should last a while. It is about the same size a a generation 1 SBC and smaller than an LT1. The pan is allot wider, but it is actually just part of the block. The alternator is the only belt driven acc. I have. It is a 60 amp mini. Correct it is not moved over, and no special axles, but you do need a different tripot joint than stock. It has to do with clearance of the flywheel. the stock water pump would not fit without allot of cutting. I contacted Meziere and they explained the coolant flow of an LS1 to me. There is no cross over of coolant as in a gen. 1 SBC or LT1 (which also has some oddities in cooling that I won't go into) so I fabricated adapter plates and used a remote pump. I will post a picture of the original pump and you will see why I am not using it.
I know the crate motor you are speaking of very $$$$, but would be easier I heard it comes with an auto harness???. Painless also makes a LS1 harness For hotrod applications but once again $$$. I opted to modify a new GM stick harness($255.49) it is not as hard as I thought it would be. Once you know the pin outs you can sort out what is needed and what isn't. I also plan to get LS1 edit or custom programing in the future.

I'm the other person doing an LS1 swap that Alan referred to, although we haven't emailed each other for a few weeks now.
I installed and started my LS1 yesterday morning and ran it for about 10 minutes. That was a real thrill. On these projects you can't test anything until you test everything at once.
As you know Alan, we did a few things differently. But the details of my swap belong in a different thread.
Again, great job. I especially like the clean look of your installation.

Hey orville good to hear from you . Yes we did do some things different to overcome some of the same obstacles. One thing that you did better and I would recommend for anyone else is the clutch setup. Quartermaster twin disk set up. Did you get the throw out bearing and hydraulic slave worked out? I am happy with my clutch now and seems to hold just fine, but twice the friction surface has to be better. The covers help clean things up on the LS1 they are only $40 through gmpartsdirrect.com. If you would like the part numbers let me know. They also have them for the ZO6 which are red but are $60 a pair

It's installed but not tested yet. Looks like it should work, though.
About the covers, it's a good idea but since I'm in California, I've had to retain all the emissions gear with the attendant wiring and plumbing and I don't think there's a cover big enough to hide it all.

Corvettes come stock with them, you have Corvettes in cali dont you? Just order a set, and make modifications as necessary, would clean up the engine bay nicely

Isn't that the point? The engine IS out of place...it's made for a Corvette. Would you rather he put the Fiero motor back in, plenum and all? I mean...it would look like it belonged...and have about half as much power.

no, that isn't the point...that car is Bad A$$, but the car isn't a vette....kinda like it when people badge a car a "type R" and it isn't a type R.....kinda ricey to misadvertise, but to each their own, nice machine

I think what he is saying is, it is a corvette engine. Therefore it's not misadvertised. Now if he had a stock GT and put Corvette badges on the top of the intake, that would be misadvertised. I like the covers to say Corvette.
