I'm ready to pull the trigger on ordering parts for my build, but I wanted to get some feedback to make sure I'm on the right track.

My goal is 500hp

LM7 5.3
Heads: https://www.summitracing.com/parts/a...make/chevrolet
Cam: https://www.summitracing.com/parts/sum-8707r1?rrec=true
Head Gasket: https://briantooleyracing.com/btr-he...20OEM%20units!

I'm planning on boring out the 5.3 to a 5.7 but I'm not sure which pistons to use? Any recommendations? I would like to use stock rods.



Is my head and cam selection good? Are there better options for around the same price range?

For dependability on your rebuilt motor, don't forget about the sensors - knock, crank, cam, ECT, MAF, MAP, IAC and TPS. The knock and crank sensors on an LM7 are hard to get to and I replaced mine with the motor sitting on the shop floor rather than at some random difficult time and place later. YMMV but I'm not a particularly lucky person. Luck favors those who are prepared.

What Intake do you plan on using?

I am relocating the knock sensors to the side of the block vs the top.

The plan is to run a LSXR 102 intake with a 102mm throttle body.

Mahle Power Pack if you want a really good piston at a fair price. The Summit Wiseco's are good bang for the buck. DSS and UEM are also decent cheap forgings, but I think it's worth the extra few bucks to buy the Mahle's if you are shooting for big NA power.
