Anyone running EFI

Derek isnt that lt-one equipped with a multi-sequential FI system and opti-spark? But your right about the HP potential. I doubt if one could pull 350 HP with all the bells and whistles.

Grumpy, if you are talking EFI'ing a first or second generation small block , in my opinion the Tuned Port Injection is the way to go .... and they look so damn nice.

That's correct... on a stock bottom-end, about 425hp at the crank is the limit while still retaining some street-manners. As much as I'd love to have 425hp right now, I know I'll love 550+hp even more later.

LS1 and 6-speed are sitting on the floor in the garage... still need to collect parts. I have the headers and the engine mounts, but that's it. I do plan to have some work done on it before I put it in though... Heads/Cam for sure, maybe more. I really want >500hp.

Yeah, I got a six speed (zf) in my '93 vette. Factory numbers puts it right at 300 hp. I put a chip in it and increased to about 330 by just having it run cool (185 deg instead of 220) but in 96 GM put roller rockers and more agressive cam in the vette and raised the compression from ten/half to ten/three quarters and called it a lt4 .... still only put out about 330 after all the improvements.

I cant imagine getting big HP (like 425) without going with spray!

But the lt-1, in my opinion, is still a great engine once the overheating issues are dealt with
