what all specs are you looking for???

There are several V8's in Audi's.

All-Road V8 - same engine blocks as 2004+ S4 and A8

Old V8 - A6 4.2, S6, A8, S8, same engine block - different cams, intakes, exhaust manifolds, etc.

Work your way from there.

I have a 1995 Audi Sport 90 Quattro with the 2.8L V6.
I am thinking about a 4.2L V8 engine swap.
I think I should put in the aluminum block to better closely match the V6 steel block weight.
I am only in the planning phase.
It could take several years to complete.
Any suggestions would be helpful.
