My suggestion would be to copy the highest HP
389 engine: (the 1966 GTO) and use the same cam,
lifters, etc. The tri-power for a 64 GTO or big
car would be correct but any 62 to 64 tri-power
would directly interchange. I know the manifold goes back to 61, guys but it has been a LONG time
since I saw a 61 tri-power. If you are going to drive the car you have two choices. Retain the high compression motor specs, etc and buy good but
expensive gas for occasional drives or put in lower compression pistons and run the panther pi$$ that is out there in quantity. A set of the "Long Branch" exhaust manifolds would help the car breathe but are not totally necessary. Tom V.
