Okay im pondering a new engine combination for next season. In my posession I have a good 400 block and crank, a good 350 block and crank, a good set of camel hump heads, and a ported set of 305 heads with 1.94 and 1.6 valves. What would you guys build if you were me? In the class I race in we are limited to a 500 cfm carb, cast iron intake, and cast iron exhaust manifolds. I was thinking about building a 377 with 5.7 inch rods and the camel hump heads. I was gonna build it to about 12.5 to 1 compression, since this is the number to shoot for (or so im told) Id rather not build a 383, since ive seen way too many grenade in the past few months. Any ideas?

I'd build a 406 with gobs of low end power and then gear it to turn 6200. It'll run all year and be very drivable when the track slicks over.

Hey 81-

If you dont mind me asking, what do you have in it? Like what heads, pistons, rods, crank, and cam? Whats your compression ratio? Any suggestions on how I should build mine?

Pitbull, if you have to buy rods (you didn't say), I wouldn't use anything less than 6" rods, no matter what combo you decide on. And the price difference for a 5.7 or a 6" rod piston is nearly zero...
