Default Building a 370

So I'm going to sell the short block I just picked up and buy another short block that is already bored .030 but doesn't have rods or pistons. But it does have heads.
Not sure which heads yet as I haven't went and looked at it yet.

I have ls2 rods with stock crank so I just need to pick up some 4.030 Forged pistons. Everything I see is about $650 which is more than I paid for the short block. Anyone know how much a set of used forged flat top 4.030 pistons would go for?
Just need a rough guess so I can make a decision on used or new. If I get another income soon that I have lined up then I'm going New for sure.


Cam will be 244/248 .612/.615 112 lsa

If you wait a few weeks I will have my forged diamond flat tops for sale from my 408, only 1700 miles on them

I don't plan on buying them right away unless I find a deal. PM me what you think you'd want for em. I'll punch some numbers and try to get em from ya if it's within reason.

You'll need a 4in stroke crank for those pistons. Make sure the pistons you get are for stock length rods iirc are 6.098

Just the pistons.

The part number is 11519, 1.125" comp height. Might need to change rods to use them since they are meant for a 4" stroke...
