thanks erik and pat for the replies. Looks like the 402 pistons are out as there are none (except custom) that will work with anything but a stock type head (valve shrouding and clearance problems). Getting a 454 block (should find out tonight if he can find a 4-bolt for the same price as the 2-bolt), reusing the short crank for a 427+. Pistons are on the way from SRP I think 30cc dome for ~10.6:1 with 113cc chamber Trickflow oval heads.

Was leaning toward Holley strip dominator intake. 850 carb is the way to go but I'm going to run my current 750 for the time being (shouldn't choke it too much but the 850 will be better).

I appreciate the advice and want to build a mountain motor in the future. I'm a bit bummed my 402+ plan was foiled but I think the short 427 (432/whatever) will suit me just fine for the time being and might even get me into the 11's on pump gas.

Already running 4.56:1 gears so she buzzes right along on the highway ~3500rpm. To clarify, this is a mostly strip car that drives 30mi to the strip. My next worry might be traction although I never had a problem hooking with the old motor.

I just wish these crises could have come up at least a month ago so I had more time to plan (first test/tune is next weekend). Doesn't help I'm going through this while on the road and away from my books and tools.

I appreciate the input...
