damn, thats pretty weak. LT1 cars are really struggling to breath until you ditch the logs (stock exhaust manifolds)

what kind of quarter mile times would a 350hp lt1 car run? with a six speed and also with an auto.

Way too many variables but when I had 330rwhp in my auto I was running low 12's full weight but my car was setup properly. I would say a properly setup A4 with 350rwhp would definetly hit low 12's full weight and maybe the M6 with a good driver...but Im talking properly setup as in suspension, tires, gears, stall, etc. Thats the key, I have a buddy with 300rwhp thats in the 14's hence a bad setup.

well the reason i ask is because im about to do alot to my car right now and i might get close to the 350 hp range. Im getting my motor rebuilt and doing full exhaust cai, probably 373 gears and a six speed swap. I am wanting to do a cam but i dont know anything about them and my car is my daily driver. Im also going to get strano springs and probably bilstein shocks and some good tires. Just trying to get into the high 12 range.

I have the Strano Springs and love them, good choice. To learn more about cams and valvetrain read my sticky at the top of this forum its called *Stock Headed Cam/Cam Swap Guide*, that should help you out alot. If you can get 350rwhp you will go faster than high 12's if you can drive.

well im gonna need some good practice cause i have only driven my buddies cars with five speeds in them. IM sure after driving to work everyday and occasionally messing with cars here and there ill get pretty quick and consistent on my shifts. I have never had a m6 car so its pretty exciting thanks for the info ill read the sticky you mentioned sorry for hijacking the op's thread lol

I'm making close to 400 with a gm 846 cam, shorties, cai, alittle head work, and home ported intake, tb, and aluminum elbow. It's not hard to get 350whp but with just bolt ons i think it is somewhat pointless, add some long tubes, ditch the cats, and get a small to medium xfi cam and you'll have that horsepower, and will have spent less money than you would have on just straight bolt ons. people like to take the summit/ jegs advertised horsepower to heart... never the right thing to do

you will need to upgrade the valve springs, and pushrods, which you should do anyway, it'll give you peace of mind, as they are wear components, and your car is getting up there in mileage. But on that note the 350 is one of the most reliable american motors ever invented, which holds true until you begin comprising it with modifications
