I am a 1995 ZR1 owner
a frind gust bought a 1993 LT1 the engine is a lettel bet shot so we well rebult it , we saw an add in summit about an LT4 kit (heads,cam,......etc) that would replace the LT1 and produce 425BHP crank
what do you think of this scamm or real???????????????,

we are also planning to go 383Ci (8.5C/R) if you would recomend a good kit for the stroker that would help a lot i hear LUNATY are good but we are open for any sugestuns

and thin drop in a Procharger intercoold ,

You should nerver run 8:5 c/r on the 383LT1 motor that is running NA. The c/r is at least should be keep it at 11:1. And yes any 383ci LT1 stroker will absolutely destroy a stock ZR1. Sorry "KING" :)

Bruce, He has plans of installing a supercharger.

Sultan,

The hot cam kit is not a scam by any means. The Hot cam will make at least 400 flywheel hp with a mildly ported LT-1 heads. I used to run the Hot cam kit with AFR 195 heads and with an auto it put out 367rwhp.

I personally wouldn't use the hot cam with the 383 supercharged setup, but that's just me.

And yes, your friend don't even need a supercharger to dethrone the King, a 383 alone would do the job.

Comp Cams 218/230 @.05 .555..lift 114 is a very good choose and make good power. It almost like the hot cam but it a blower grind.

The cam that I am running with my 377 supercharged/nitrous is 236I/248E .571/.587 lift with 114LSA. It is a pretty radical cam, not very streetable. I am not sure what kind of results your buddy is looking for but if he wants a good streetable cam that will make good power with the blower I would say the CC305 cam.

I am not a cam expert by any means but I did do a lot of research and I am really happy with the results I got with my cam. If your friend is serious, he should do a lot of research as well.
