Mopar 350 Stroker

Okay, plenty of input happening while I been typing this, so there’s some redundancy. If you use the SBC rods, the big ends are wider (.940) than Chrysler rods (.925). The rods you have may have already been dressed down to fit Chrysler journal width, but oftentimes the rod journal cheeks are ground to fit the rods. More things that need to be properly measured. And if you get precision tools, you should also invest in a dial bore bore gauge, too. And educate yourself about engine blueprinting from the resources at hand. Plenty of YouTube videos about measuring things properly. But, before offering too much advice, we should be asking “What’s your proposed budget, and kind of heads are you planning on using?” If you use those pistons and rods, then you’d have to have the rod journals cut down to the probably 2.1 inch sbc size and measure the rods to see if the cheeks of rod journals need to widened to the aftermarket rods. Actual compression height is 1.7905 from the center of the piston pin, so a .030’ish cut from the block decks would yield a zero deck. That doesn’t account for the way the blocks came, which was usually somewhat above the 9.60 deck height spec on all the ones I’ve checked, as well as out of square and off from one end to the other. It’s probably already been done, but that’s something that you won’t know for definite until either putting the rotating assembly in, or having the deck height of the block measured at your machinists.
