5.7 or 6.0
If I had a decent machine shop here, I could expect to pay ~$450 for the machine work on my LS6 block. Then you have $200 for the balancing. Another $150 or so to polish the stock crank.
Then you add these parts:
Wiseco 2618 Forged 3.905" Flat Top Pistons w/3.2cc Valve Reliefs $649.99
Wiseco GFX Ring Set $-
Compstar 6.125" 4340 H-Beam Connecting Rods w/ARP 2000 Bolts $534.99
Clevite H-Series Main/Rod Bearing CB663HN/MS2199H Combo $184.99
Dura-Bond Cam Bearing Set $20.99
ARP 234-5608 LS1 Main Stud Kitdum $189.99
1580 parts + 800 in labor + you assemble it... or add another 450 for assembly. That's 2800 with your block. You get the ARP Mains and the better rods vs what Thompson does. So it's a wash cuz you could get those upgrades from Thompson and sell your shortblock for 300-400.
