Engine **** Pictures. ahhhh
made my day. TYVM
Question:
the LS3 427 with the 4.25" stroke vs the LS7 427 with the 4.00 stroke, what would be the rpm difference, and which would provide more torque in the 2,000 to 3,500 rpm range?
ie out of corners and UP to speed. Yes I do know that each engine is specific for the intended build purpose.
TIA

$1549 - GM LS3 Block
Piston prices are available here http://forums.corvetteforum.com/c5-t...1-diamond.html
Were using a 4.125" stroke. The larger stroke will make more torque. We recommend using the 4.000" stroke in road racing applications because it allows you to use a better piston design that's going to be beneficial in extended high rpm. The biggest difference in power curves and rpm levels is going to be in the top end of the motor, since the LS7 block will accept LS7 heads and the LS3 block will accept LS1 or LS3 heads. The LS7 parts typically make more power in the 6500-7000 range and the LS1/Cathedral parts typically make more torque.
Sounds great

So it sounds like all the interals on this one are forged, but it is probably not best for boosted applications because skirts too short/piston might pull out of cylinder?
If so, what would be a proper stroke that would not compromise boost capability, and what would the cubic inches come out to on that one?
