Well-----I raced 392s and I have one that I'm building

However---If I didn't have a 92 I would be exstremely happy with a 354

I don't remember all the differencences, but do remember that there was a combination where they used a spacer between the manifold and heads

I build a lot of other engines and I have said for a long time that the crankshaft doesn't know what it says on the valve cover, but that doesn't cut it when it comes to a HEMI (392)
