Im looking at a 370 by tsp buuuut.. Here lies my problem,
I have no idea about any of the options listed. I don't want mismatched parts. It's for a DD Na car. 01 z28. Not a max effort type motor but a healthy one. Please help me figure out what to add to my shortblock!

I would go with a flat top piston, with a -2cc relief in them. This would allow you to run a nice size cam with out having to worry about PTV clearance problems, and not giving up much in the compression department either.

I would call TSP and speak to Jon or Matt. They are great guys that will talk to you and work with you and your goals to build what you want. Just trying to figure it out over the internet you are almost certainly to be disappointed with whatever you build. Talk to the pros and get it done right.

Yes. Call. Making important decisions based on someone's internet expertise will only get you in trouble.

Flat-tops for an NA build will be the way to go! I'd still recommend milling those 241's down a bit to get some extra compression out of the build! Callies Compstar or the Lunati H-beams will be great for what you're doing. GM crank is fine and will handle plenty of power beyond what your plan is here. ARP main stud kit would be nice IF you have visions of adding more power (nitrous??) down the road for some added insurance against deflection. If we use the Gen3 block, you do not need any conversion package or anything like that.

Let us know when you're ready to go, or if you have any other questions!

I don't plan on any power adders spray turbo or sc ever. All motor. I would love to be at 450 to the wheels with a head/cam (changing from 241s later)
