FFR428,
The pro-gram stuff is suppose to be nice. The caps are made with plenty of extra length on the 'nibs' to allow for fitting and maching. You can probably find a good pair of 427 caps and save a few bucks. I think the pro-grams are about 100 apiece. I recently had Bill Parham of Southern Automotive cross-bolt one of my 428 race blocks and it came out real nice.

I've got to disagree with Al on a couple of things. For a high-horse 428 that's going to see some track action, I think cross-bolting is a good idea. I've personally seen and heard of plenty of 428 blocks spitting from the mains to the cam journals. The cross-bolting cures this problem plus you get the '427' look. Also, cross-bolting keeps the main caps from 'dancing' at high rpm. It's not the high rpms that kill the blocks, it's the torque the engine is producing. I also think that 500 HP is totaly attainable with a properly prepared 428. I've been running NHRA stock class for over ten years and am actually amazed at the HP that can be squeezed out of these engines. We run factory carb, cast iron intake, unported heads, 0.525 lift cam factory dish style pistons (10.6:1), etc and the car runs 10.50's @ 125 MPH carrying 3400 LBS.

Just my 2 sents.
