I talked to Brian Thomson last summer on the new engines and it is going to be awhile before you be able to put an LT1 engine in your first gen.

I understand, just letting the original poster know you don't need a stroked 6.2L to reach those power numbers. You can achieve it with a cammed LS3 in my opinion.

I bought a Speartech harness for my LS418 TVS 2300, but actually it was not tuned for a supercharged engine. (Speartech sent out a stock ECU, but it was still setup for a stock fuel injection). I had to hire Rich Gala from the former W2W to tune it. So, I suspect that Speartech is selliing a stock ECU with this harness. Also, you don't want to use a 6L80E, because on a 67-69 Camaro's you be forced to raise the tunnel for that transmission swap. (Well, my floor pans are rather detailed) Now if you use a 4L80E, it bolts right in the transmission tunnel without raising it.

When I talked to Brian Thomson last summer(builder of Stielow's engine), he said that ECU is ant-tamper proof, but here is a more recent article that sound promising. http://www.streetlegaltv.com/feature...t-factory-efi/

He wants 500rwhp, but you are saying something like this engine.

I can't say that I had a high compression LS engine, but I did have high compression SBC in a 383 612 hp. Oh, that sounds similar to the SBC. Yes, it would work. Although, you need to change the motor mounts, similar to what was done on Camaro XV to LS style rubber mount or it vibrate the car.

I got to drive Brian Thomson's Chevelle 850 HP / 930 TQ on pump gas LSX, and it was smooth. You could take it on the power tour and not have any problems. Depends on what you want, but I had both.
