LS7,LQ4/9 383,or LS3 396
 

I am saving to build a 2nd or 3rd Gen Camaro and have seen a few strokers in magazines and on the internet.

The LS7 is a 427 CID from the factory so it doesn't need to be stroked but if this was setup for Forced Induction(forged 9.25-9.5:1 CR) with two Precision TA-5557 turbos or a F1-A Procharger with 8-15 psi would it survive?

A LQ4/9 bored to 4.005 from 4.002 with a 3.8 inch stroker crank is 383 cid and a LS3 bored to 4.071 from 4.065 with the same crank is 396 cid.

Based on cost and durability which would Ya'll use.

I would go with a LQ9 stroked out to 408 cubic inches. This would require a 4.005 bore and a 4.00 inch crank. the block is made of iron which should help keep the cost low and offers more strength also.

Go with the LS7 you know the saying

"theres no replacement for Cubic displacement"
