I have a Ls1 looking to be stroked
Keep alloy block go 383ci or get new 6L iron block?? 3.905 bore or 4.005bores?


Will be filled with compstar rotating assembly,
AFR 235cc heads, dual valve springs, 230-240+ cam, chain, UPD, morel lifters, YT rockers,ARP bolts, valves
Weekend driven will hit track occasionally but want tuff street



Any input appreciated on limiting alloy block or go for cubes
Cheers

May as well go with the bigger cube iron block and sell your left over short block.
