who me? while I'm usually guilty of that - you need look to Alan for such shenanigans. That said, I could ask what they think of a duramax (it would probably fit under that silly hood scoop...

But seriously, it doesn't take a big change in the intake manifold height to use up all the space under a C3 cowl hood. I raised my l88 hood 1.5 in and still needed a drop base ac with the factory dual plane manifold. You might be happy with that hood.

I'm certain it will need something - but that scoop is a large bit too much. All I know right now is that it's not going on the finished project and that the flat hood won't work either - so the end will surprise me as well... that said, L88 hood with mods.... whatever it is, I plan on road courses and autocross with it, so seeing the passenger side is kind of non-negotiable.

love the deux chevaux - when I lived in France my first, serious girlfriend had one that she eventually rolled... before that.... well that suspension is cushy for far more then transporting eggs across a field

​and no, the stack isn't right - but it's the basic idea.

I'm still trying to decide what motor. It didn't get any easier this last week, I got as trade a 4 bolt main 454, and have a steel 427 crank... I really, really liked my last C3 - the knuckle-dragging simple no PS, no power brakes, manual transmission, stupid-large cam, hard-riding car. It was the hardest-driving, slowest-fast-car I ever had and absolutely the most fun car I've ever owned... decisions. Do I make it daily-driveable or build another 'race' car for the street?

I don't need a DD and the only reason I sold the last one was because I didn't want to repaint it when I put the flares on it (that and the suspension was done - and I wanted rack and pinion and the guldstrand rear setup)

Thoughts?

I had a steel head 427 in a 68 and really liked it. Headers, cam, intake, carb, msd billed dist, and msd6al really woke it up. You combo will be a few more ci's according to what I read.

Definitely do alum heads, alum intake, & alum water pump as well as pull weight off front end.

4.250 bore, 3.760 stroke, 426.72 ci. 454 standard block, 396 crank.

I will do as much lightness as possible should I go the bbc route.

You are right, I went back and checked, they did an overbore.

My opinion, an alum head big block will sell better when you want to get rid of the car. But, the LS take out engines are tempting.

It's not 4 bolt block, we're back to LS... though maybe LS 427

I have a very good friend that, after driving my last C3, is now building his version of a C3 (Regis on Corvette Forum) that's doing a SBC 427 - I can't convince him to go LS, so I think I'll do the next, best thing.... build my own - though with that said, I'm not sure I can get the cubic inches with a 6.0 block (and that would stop that thought process immediately).

He's more driver comfort but still race-car-oriented. My concept of driver comfort is "if I can survive, it's perfect" so my going to 11 isn't really a challenge, more just kind of what I do.
