What do you plan on doing with the engine combo ? ... have you pulled the heads off that 413 ? ..... the 906's can not be milled enough to get decent compression with that shortblock.

Have you seen those dished pistons ? What can i find a set of 516's on? This will be my first build. And I won't be jerking the heads off 'till this weekend, so I've yet to see this 'dish'. But eventually i would like to punch the block .062, and make a 426. But for now, BUDGET is the name of the game. Back from hiatus

It requires a different amount and possibly a different angle to keep things the same. We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind. - Stu Harmon

And YES .. you do have to cut some off the intake side of the heads to make everything line-up OK after cutting .060 ... the amount and the formula escapes me at this point.

partfiler69 Still Wondering Joined: Apr 2008 Posts: 223 Poplar Bluff, Missouri	Thanks for the help, everybody. I'm also wondering, is it possible to put a set of 383 pistons in it, or do I need 426W pistons? Back from hiatus

Anonymous Unregistered A	I think someone did some measuring and figured out that 383 pistons would work in a 413 (bored to 4.25) with a 4.15 stroker crank. Not sure anyone has ever actually tried it, though. That would make it a 472, BTW.
