Have a .60 over block, stock crank, going to purchase scj heads and kb flat top pistons, shooting for 500hp, can someone please point me in the right direction on my next step on what I need to figure out, where do I start cam? Rod length? Been searching for weeks but I can’t seem to find an answer that makes sense to me

Step 1- Find a good machinist if you don’t already have one.
Step 2- The SCJ head and a flat top piston isn’t going to make for a pump gas friendly combination if that’s what you were shooting for.
Step 3- If you’re using a stock crank a stock length connecting rod (6.605”) is gonna be what your looking for, ideally an aftermarket I or H beam.

If you have the Enginetech pistons they wont work with a SCJ cylinder head, the valve reliefs are in the wrong place. Also those look like a cast piston which doesn't really belong in a performance engine application.

I found one on speedway.com, didn’t see anything about compression or fuel, guess I should call them

With a non altered SCJ head and a piston at zero deck you’ll need a dish in the low 30cc range to get you down into the mid 10’s:1 compression wise.
Please don’t take this the wrong way but it sounds like you are in way over you’re head here. Have you built (not assembled) any engines before?

No I’ve never built and engine before, I’m confident I can do it though, I just don’t want to build a stock motor, I want to put together a hammer, I know I can check and measure clearances and all that stuff, just not sure what combo would work for my goals

Sounds like you’re gonna want an engine that makes a lot of torque down low with a broad torque range. With 4.10 gears and a non OD 4spd you don’t want an engine that wants high revs to make power.
