Default 5.2 Magnum stroker crank

Does anyone know if a 4" crank will clear the 5.2 blcok with out cutting it? I can find stock stroke and the stroker crank i might buy is 4" and stock is 3.310 a .690 bigger stroke I'm guessing ID have to cut the block or no?

THe pistons used were custom dish pistons, which ensured there wasn't an issue with valve clearance

Yes you can use the 4" crank but you have to make sure it is for your 318 as the one for the 360 has different sized journals. Instead of coming on here and asking tons of questions the first thing you should do is buy this book; How to Build Big Inch Mopars.
After you have read the book then come back and ask all the questions you want.

Here is an article in a magazine called Engine Builder. They built a 392 stroker and pulled down 477HP@5,800 rpm & 481lb/ft@4400 rpm plus they made 421lb/ft@2800 rpm. Them are some nice numbers from a little old 318.

Better yet contact the manufacture of the kit! They should know if any mods need to be done or not. You also have a charge for machine work, Did you ask if this includes mods to fit the crank if need be?

Mopar Magnum engines have a tall deck which allows us to not have to do any clearance on the block. That is why I suggested you buy that book as it explains all this in there.
