Summit Cam Help/Recommendations

Hey OP, sorry to hear about the engine condition. It you are doing that LA engine, then I looked at the Mancini kits and am not all that impressed. The only one with pistons has cast pistons from Sealed Power; those are probably low compression like you have. Plus if you pick your parts, then you can get better things like thinner head gaskets than the thicker, compression-reducing head gaskets in the standard kits.

As said, count on the bores needing to be rebored for oversize.

Crank should be inspected and measured.. .may be OK, may be not.

For your 'driving-around' use, and with a budget, I personally would not pay to re-condition the rods. It is likely not going to be any issue if you are not leaning on the engine all the time.

I would recommend you look seriously at these pistons: H116CP.
Speed-Pro Hypereutectic Pistons H116CP 30
Stock weight so no re-balance of the crank is needed.

Use these, mill heads .030", and use Felpro 1008 head gaskets, and your static CR has jumped form right a 8.0 to 9.5.... now you can use those cams you listed up front without dumping the low RPM torque. You now have ALL sorts of flexibility in cam selection.

Bottom line: That one parts change, the pistons, just moved you into a much better performance range. It is not a cheap bullet to bite off if you are on a budget.

The suggestion of good used Magnum engine is sounding like an option worth exploring right now. Better compression ratio right off the bat,
