What was his resoning for this combo?
As far as I know clevland heads won't fit on a windsor series block. They are 2 different 351 designs

302's and 351W's are both windsor small block fords. So I'd think that either the cranks or the bore size is the same.....
I am so tired, I'll just stop yabbering and do some reading

I'll PM you those links to the summit stuff in a bit, sorry for the delay.
