Trying to nail a 120mph trap in the 1/4 on DR's... maybe a 11.8 or so.

Oh yea... also hoping for 415rwhp/400rwtq

 

that motor isn't going to like the stock throttle body, my buddy with a le2 383 was pulling vacume through a tpis 52 mm so he went with the monoblade. Your going to want to go with a 58mm unit to optimize that setup.

 

ET possible with traction and luck, traps probably not. (most likely around 118)

 

I am gonna go with a 58mm tb... just not right away due to the financial part of things. I am also going with 4:10's in the rear.

 

We have a guy over on Michiganspeed.com, Al Fox, thats running a H/C/E (346ci) LS1 into the low 11's @ 118 I believe.

Exact times: 1.501 short time, 11.299 @ 118.59mph. A4 346ci LS1 with H/C/E. Good luck, I think with a LOT of tuning and getting your 60' down with a nice big 4000+ stall you'll see your 120mph traps.

 

Too many variables but it should be possible.

 

M6 here...

I know they're many variables and i'm not hoping to get EXACT numbers. But just looking to get close to those numbers. I want to be able to take any stock Viper n/a (I'll be spraying 200 shot). If not a Viper from a dig because of traction issues and breaking crap, then maybe a roll. Just want to beat it one way or another. haha

I just want mid 11's with a 120trap. Prediction from a few is actually 430rwhp with similar with a nasty torque curve. But thats with the tb gears.

 

oops skipped the T56 part. Just launch the bastard at 5000 rpm. But make sure you have a Ford 9" under there.

 

I'd hope for much more rwhp/rwtq than that with ported heads and a 383.

I should add, in all fairness, that although there are people who have gotten away with such a setup on the stock rear... For every person who posts about how they spend a day running 1.5 sixty foot times, most of us break things when we try to launch with a stroker becasue of the significant amount of torque a stroked engine usually delivers.

I know I spun my transmission the very first run after my stroker was installed.

I do have a 12 bolt because every 400 passes it would break on my old internally stock motor, just like clockwork. I installed the 12 bolt prior to the stroker and have not had a problem since.

I also went to 28" tires which slowed down my sixty foot times. to keep me mostly over the 12.00 cutoff for street class at most tracks.

I know this should be in the drag race forum but perhaps some folks will chime in who don't visit the drag race forum very often.... I will move it in awhile....

 

Why is that? 430 rwhp is right around 505 hp at the flywheel. That's roughly 1.3 hp/CID, which isn't too shabby for any street motor.

 

Actually, 505hp is more like 445+ through a 6-speed and 10-bolt.

I'd be mad if my stroker didn't make at least 450rwhp with heavily worked LT1 heads/intake.

I highly doubt you will make it without some serious suspension work ie, lca,s subframes, hals, tq ar.. I learned that valuable lesson when I was cutting 2.2 60's on the bottle.

 

Depends on what driveline loss figure you look at. I usually do 15%. Ultimately it doesn't matter if it makes 350 or 450 at the tires, as long as it runs the number.

 

How many LT1 motors you see with 450+ using stock castings? All motor anyway...? Daily driver?

Lloyd said that hitting 430rwhp shouldn't be to much of a problem with all the supporting mods... i'll be missing the throttle body and gears for now. But they WILL be installed, just not right away because I STILL have to get the exhaust and all that crap... oh man.

Just want to wail on any stock Viper n/a and hoping that 430rwhp and similar torque and a minty fresh torque curve would get me what I need to nail mid high 11's and close to 120mph traps.
