Jeff,

Since our engine stands on the chassis are the same with FE and SB, it's hard to say exactly. I'd guess that about 5%-10% of 427SCs have SB engines. I think we've done 3 or 4 429/460 engine stands in 650 chassis'. They don't fit very well, vertically - lots of restrictions on intake systems to clear the hood.
