*sigh* I was looking for a link or something about a car in the hybridz gallery, not a sermon, but whatever. I've looked into the weight differences and off the top of my head the std. BBC is around 200lbs heavier than a std. SBC (std. meaning iron heads, manifold, etc.). Aluminum heads, waterpump, intake, etc. offset most of that. Both motors share the same rough short block dimensions, the heads are larger so the engine set back will not be as great as some small block installs, but pretty close. As for torque turning the car into a pretzel, I'm not worried, subframe connectors are a given though I'll likely not install cage. I'm going to build the engine as per the Edelbrock power package specs: http://www.edelbrock.com/automotive/chevy_2c.html. I'd expect to see 400-450 HP out of that setup, torque should be in the 450-500 range. Not an insane number IMHO. Now I know I can get numbers like that out of a small block without much trouble, but I think I'll end up with a more drivable car building that kind of power with a big block. My initial plans also include a tremic retrofit T56, R230, coilovers and Wilwood calipers and rotors. Looking at the pic I posted originally it looks like under hood clearance is an issue. cutting a hole in the hood is not someting I'd do. I was thinking I'd follow the lines of the bump in the stock hood and modify it into a cowl induction hood.
