11.4x or better all motor...who has done it?

Must be with HR cam and preferably with stock casting heads. I'm thinking about trying this with my next setup with a 383 with LE3 heads/cam, and some low 1.5 60fts with some weight reduction. I'd like to keep it a daily driver also. I don't think it'd be that hard, but I was just wondering who has done it already and with what setup.

I can't remember his screen name, but I do believe a guy on here just recently went 11.4X with a stock bottom end, ported heads, and Joe O cam. Hopefully he'll chime in here.

Ken runs 11.41@117 with a comp cam 230/236 and combo motor sports heads Lt1 in a auto car. Still has a 10 bolt and a 4l60e.

Local guy runs 11.40s @ 121 on motor (A4) with GTP heads, a GTP6 cam, and a 396ci motor. This is off the footbrake (doesn't flash because of stock rear). Soft 1.6s.

I havn't taken mine to the track yet due to a few complications with the oil pump.

He's got to have some slamming 60' times, right?

Yup, Crane 210/224 or something like that for the cam. Not exactly the most streetable thing from what I hear though (severe weight reduction). But doing it none the less.

Thumbs up

11.26 @ 118.94
Stock bottom end, ported factory LT1 castings, 1.94/1.50 valves, hydraulic cam, A4 3.73's.
Setup really needed 4.10's for some LOW 11's.
Race weight was 3570.

Ran 11.4s with stock bottom end, stock ported castings, custom cam and 3600 vig. Those were just shakedown passes. The car had stock suspension and cut 1.52 60s with a 3.73

You should easily be able to run low 11s with a stroker on pump gas. I would think some 10s

10's is the true goal, and to do it driving to the track and not removing anything when I get there. A local guy is selling a 383 with the LE3 package for a good price, otherwise, I'd just do a 355. I want to do it with Lloyds heads/cam, a 4l60e and a 10 bolt. My current setup is running 11.84 at 114.7 with stock bottem end, Lloyds heads, and a small Joe O. cam (~220/226) and a crappy 1.65 60ft.

SAR, did you do it as you could drive it everyday or was everything out of it and no belt?

So, has anyone hit 10's on yet on with a HR and stock casting heads in a 4th gen in what could be a daily driver?

You're the one I was thinking of in my first post. I remember seeing you on the EFA forum also.
