not quite stock
That’s what I was told when I put the shop list together over on ZR1.net forum. I was contacted by a member who had met with him. If not open now I was told he should be soon.

car is still running well!!

It will keep you busy. I enjoyed it but it is tedious work. Cheapest HP I ever got.

AND, with essentially NO sacrifice in "dirvability" or gas mileage! And, if there's any doubt that the LT5 could benefit from more air, one only has to look at the gen-III LT5 which was intended for the 96 MY.

regarding concern over the injectors/grommet seating too "deep".........an easy fix is to install a washer under the fuel rail attaching points, which essentially lifts the injector in the housing to insure it does not go too deep if porting is extreme, and /or there has been some material that has flaked or cracked away. just fyi

Thanks Jim. Good to know. At the moment I am trying to figure what the gap between the master cylinder and booster push rod should be and how to adjust for my 92 ZR1. I just posted a thread regarding this. If you have any wisdom to share I would appreciate it.

Thanks!

even without the variable cam tech that was destined for this engine it spanked out a bit more than the 475 target and was running a caddilac ecm with a single big injector graham should be proud for bringing this one back

I believe Graham used a MegaSquirt for the Gen3.
