First, you'd want a stout trans behind something like that - a T-5 definitely not.
check these sites for SVO info:

http://www.oemfordparts.com/lineindex.asp?LineID=1
(also for engines/blocks/parts)
http://www.FORDPARTSNETWORK.COM/ for good discounts on gen Ford parts
the SVO block is hi end strength & cost, for
heavy duty racing, probably overkill for anything
else. Check out the 351 Sportsman blocks, careful, not the reman but the newsly out 351 Sportsman. Otherwise, even a good 94-up truck 351W is plenty sturdy for hot street and is a roller block.
