I thought I heard the Q45 was a bit wide, and that there may be a narrower version, but don't recall what it came out of that is rumored to be narrower by 1.5-2" or something...

I'd cast my vote for an LS1 if I had more moola, but will probably go LT1/T56 myself. I like naturally aspirated V8s, and know how to work with them - and likewise like FI, do not want to go carb.

Turbo would be nice on a V8, but the power levels would already be "insane" enough for me at around 500 crank HP, figuring 650+ on a turbo V8, ridiculous, and lots more $ to do it "right", meaning liveable on a road race or open road race course, where you are already battling heat, any more is going to be tough to fight.

I will probably setup a nice NA 2.8L or turbo 2.8 in the meanwhile though. A local guy built up a 3.1L stroked 2.8, with a streetable cam and made 288 crank HP, definately enough to keep me happy for awhile at the track. The cam is about a 230/240 but he doesn't recall for sure.
