Fastest stock bottom end 6-speed? How fast is the fastest stock bottom end 6-speed f-body? I just went 10.20@134 with my heads/cam car on 200 shot, six speeds inc built t-56. might have a bit left in it. tryin to dip into the 9's. anyone with a legit stock motor with only heads/cam power adder ever go 9's?

none of these cars are stock motor. this car is straight from the showroom bran new I've owned it for years I put heads and cam on it and spray it. the car is stock as hell. I'm talking about stock motor ls1 f-body's. I could easily put a new motor in the car and go low 9's with this trans. that's not the point. I want to push the stock motor as far as possible with a t-56.

joe and amber charged me $1,200 a few years ago. but they closed up shop and dont advertise doin trannys anymore. i'm sure if you live close they will do it in the garage at home for you. just not under the business name. Finish line trans is right by me. chuck at finishline trans ( FLT) quoted me $1,900. they are definetly the next best place hands down. but $1,900 was too steep of a price.

I have a walbro 255 in tank with stock lines, stock rails and FAST 36lb injectors. I run 93 pump gas. the kit is a dry nitrous outlet singe nozzle. ( made the kit for like $200-$250) the car was tuned strictly for spray. it runs a bit rich on motor because the MAF was not correcting fuel enough, but we got it running hard on the bottle.

according to the list that was posted long ago in the manual trans section, speedyws6 went 10.02 with the stock bottom end and nitrous. thats the fastest that is recorded on a list. I went 10.20 which would be 2nd fastest recorded stock bottom end 6-speed f-body. I have talked with the other 4 or 5 guys that are on that list in the 9's that says 346 or 347ci and all have said they had full built motors when they ran those times. none ever went fater than speedy when they had a stock bottom end. now i'm sure theres all kinds of faster cars out there that dont even post on ls1tech. so we will never know. I should be able to bust out a 9 sec pass in spring with no problem. my 10.20 pass had some nitrous issues and needed suspension tweaking.

I bought a bellhousing from smokeum99ta couple years back. when i spoke to him on the phone he claimed his 9.80 on n20 was on a stock bottom end. i asked for details about his engine but he straight up told me he wasn't gonna tell anyone about his set up. so far as i know thats the fastest, if his car was a legit stock bottom end.
THE 6SPEED LIST NEEDS UPDATING!!!!! WTF??!!
