I think I am forced to agree with the Punisher..  My 4.9/auto bone stock is running consistent 15.1 That's with tires that were not hooking up well and a load of crap in the trunk. Also, unlike most 4.9s my car has a full exhaust with a CAT. So with new tires I think I could get to high 14s. But I don't think you are going to get to the 13s with a bone stock 4.9 [This message has been edited by jscott1 (edited 08-28-2004).]

I will be running a Carbed 5spd Notchie with TRUE Dual Exhaust and I hope to be in the 13's Will be able to post when I get it done.

I agree with the punisher here. Rock crawl’s 13.9 was with a manual tranny and some mod's. I'm willing to put money down the a stock auto 4.9 will run at best 14.6 (I'm in the 14.7's now). Every time I drive it at the track I seem to get faster however I really don't think I'll break 14.6 without doing some mods. I hope to be the 1st person to show what a stock 4.9 / auto will run on a 100 shot of nitrous. Right now I'm waiting on a few required items (imho) before I spray it (MSD Ignition, MSD Retard & Upgraded fuel pump, the stock Fiero pump is only good up 250 or so by other people’s observations)------------------

I have driven and been in many 4.9's incuding Rockcrawls modded 4.9. The 4.9 is great for the light to light low end grunt. With the caddy transmission, using caddy a caddy torque converter, you will be going down the highway at 80 mph and 2000 rpm. The combo is set up for factory cruising not for drag racing. I am sure a stock 4.9 with a standard transmission would drop a second in the 1/4. Even without a caddy trans/torque converter it would drop into a consistant mid to high 14's. Most people who pay for swaps are looking for reliability not a mix and match to get it down the track to be quick enough to satisfy some punk(s) with thier expections. So yes. . . there are many things you can do to the 4.9 to increase the 1/4 mile performance but changing from stock factory takes away from the daily driver reliabilty. I would say if you want a drag car then don't go 4.9. But my wife has well over 250 1/4 mile passes on her 4.9 while other 3800 sc have broken before reaching what she is producing on the track. Also sbc 350 are complaining about traction or tranies or I could have done better if I tried....... So please, the stock engine bashing is really lame, my brothers stock sbc in his auto firebird does 16.5 sec in the 1/4 mile. A stock auto V6 fiero is mid 16 sec but light to light is not a challange for a civic at times according to some. So why is a stock 200 hp V8 auto a problem if it produces times that a 200 hp engine should. Light to light it will have no problem even if the honda has NOS.  We have proven the 4.9 to put-out mid 300 hp with a 12.2 ET quarter mile and are now surprisingly in the top 10 of fieros on the 1/4 surpasing many other known "better" engines according to some.
Anyways I have been rambling, What I am saying is why compare a stock automatic 4.9 V8 to a modified whatever. There are many stock 350's not pushing out 200 hp that thier owners are more than happy with.
The 4.9 is an engine that as it revs it looses power, which is really a different sensation that most people are use to, and must be driven in to feel and appreciate the right-off-the-line feeling.

Stock 4.9 and stock chip, 4T60E, 2.73FD, BF Goodrich 245-55-17 with car at 2990 with me in it.
60 ft 1.896
1/8 9.290@ 73.6mph
1/4 14.694@ 90.172mphThere is slight tire spin, so with good rubber, maybe could find another tenth or so. In the 16 passes down the track, I have run against Mustangs, Camaros and Firebirds that were mid-high 13 second cars, and in every case, beat them to the 1/8 mile (that includes a New Corba R) . After that, it is over. This is why the 4.9 is such a great street combo. It has the power where it counts in light to light racing.

Who cares -------I like the way it sounds!!!!! No 4 banger or v-6 will ever sound this good!!!!!!!
If you are reading this and like the way a 4cyl sounds with a poopcan exhaust then you wouldn't understand----Those of us born a few years back appreciate the sound of an American v-8. My 2.8 was tired and the caddy will give me good gas mileage plenty of power and nice reliability for a good price and it will always sound wonderful to my ears.

As most will tell you, the 4.9 may not be the best choice if you have the dragstrip in mind. However, it's damn hard to beat (even in stock form) when dueling in light to light challenges.
