with my 13.96 @99MPH 3.4 DOHC what people dont know about that day was that i was running at as it is on the street... no slicks (h-rated 205/55/16), STOCK CLUTCH (yes thats right, i was babying it for a week before hand so it would be good for a few runs), no-burnout ahead of time (id rather have the tires slip then the clutch), i was launching at 2500 RPM to keep the clutch in OK shape (which is very low for this engine). and last but definatly no least..... this was my FIRST time at the track, i had a little stick-on pinstripe thing to tell me when to shift on the stock 6k rpm tach (i shifted at 6.5k) lol. not proving anybody wrong here, but since i was the fastest DOHC on that list, i might as well give out a few more facts about that day.
Finding one dyno of a V-8 showing less HP than a DOHC engine doesn't mean that most SBC swapped Fiero's have less power. My ZZ4 has 309 to the wheels and runs 12.387 seconds.The fastest DOHC was turbo'd and ran 12.9 compared to my off-the-shelf normally-aspirated carb'd engine. I have yet to see any real-world data of a 3.4L DOHC engine coming close to either of the above specs. Not saying it can't be done, But aside from wetpoop, how many other 3.4L DOHC dyno's have you seen?
still in a monte carlo not a fiero - but its basicly the same setup as I have in my car which is still in the tuning phase
"1995 Monte Carlo Z34" blue is before red is turbo running 10psi

Hell no, that is a nice flat ass curve. That was the great thing about my LT1 cars. Nice flat curve. Launch that car at around 4500, ride the clutch out for 1/2 a second to keep the revs up, and the shift extensions will keep it well in the powerband. I don't care if it has pushrods or not, that's useable power.

only modified ones Fieroking: 13.90@96mph (mod. 4.9 Caddy) RockCrawl: 13.30@105mph NB (mod. 4.9 Caddy-4speed)
on that list anyway and aren't those autos? I did say sticks. Cadero or whatever his name was had his swap in the 13's back when he was one of the first few to ever do the swap. I know he had a stick... I think even Ed Parks is in the 13's...with an auto. He might have a 4.10 final though...not that that's a crime.
Again, 4.9's only dyno ~160 at the wheels stock.

I think a turbine jet engine would suit the fiero best The sound is awsome...... And my torc and hp numbers will look like a nikey swooosh but it's better technology. j/k All in good fun.

you seriously think that a 4.9 with a 70 shot of Nitrous with an auto is still a full second (or so) slower than a stock manual? that 14.2 or whatever it was is probably faster than a manual, if hes an amazing driver than maby close to that time.
autos loose power at the wheels, but not that much.
...just to trow a wrench into the mix...I find it odd that I have yet to see a top fuel dragster run an engine that is a DOHC...I wonder why is that???
...but then on the other side of the coin...I also noticed that the Formula 1 type cars are running DOHC's...
...anyways, just rambling...each motor has it's place

If i'm not mistaken, DOHC's aren't allowed in top fuel per the rules.
If you really want to get into that, through around the fact that GM has a 122 cube 4 cylinder that's made anywhere from 800-1400HP
Assume that a top fueler runs 500 cubes even, that gives the top fueler a 4.098 advantage in the number of cubes. 4.098 * 1000 = 4,098 HP. take that a step farther and up it to the 1400 I've heard of ecotecs making, and you get 5,737. So I'd say it's safe to assume that given similar cubes an ecotec DOHC wouldn't be far behind in terms of power. and they've only been developing them for what 2 years? give them 10 years and see what's going on.
