What is everyone's engine design preference?

[DavidBoren]

Simple question, seeking a common consensus...

Do you think that a bone stock LS2 would show a NOTICEABLE difference if you swapped in my proposed undersquare long block, assuming head flow and compression were the same?

Only change being bore and stroke, 4.00 x 3.60 vs. 3.78 x 4.00...

I hadn't originally started this thread to be about this particular engine, but I have used it to keep the conversation steady, and now I feel I have presented my argument enough that I should be able to get an honest opinion of what I am trying to accomplish.

Actually, forget the LS2 comparison. I know my proposed engine will best a bone stock LS2.

What is everyone's thoughts on the use of variable valve timing?

Note for future boost:
The aggressive vvt cam from comp cams is actually very comparable to the LSA cam, hmm, positive displacement blower on a stroker motor with vvt? Talk about torque.

LSA cam: 198°/216° .480"/.480"
Comp vvt: 218°/222° .566"/.578"

Thoughts?
