I guess I missed the part about Dave wanting to use this project as a learning tool.His interests in oval track racing combined with his background with Fords is what prompted me to pass along the ref link.I know on the Thirdgen forum engine swap section there are a number of guys doing a carb swap as apart of the LSx engine swap.

As for me,I've said how much I regret building a 383 over a LSx.The one open question I have about the LSx series engines is given their C.I. size what kind of torque output can be had off idle without expensive stroking them.And here what I am talking about is what can be had from the local junk yard.
