Craig is correct, anything can be made to fit anything. It ain't easy, it ain't cheap - kids don't try this at home.
FWIW, I've used a couple of different BrandX pistons in the Packard V8. The Mopar 413" and the Ford 370" truck pistons can be made to work, with much machine work and custom balancing.
However, I've found the cost of modifying the 402" GM pistons and custom rods to fit the Packard V8 exceeds the cost of custom forged pistons which fit with no hassles.
BTW, Quote:
This is pretty darn close without doing any piston top milling or crank stroke grinding.
using the GM rods will require grinding the crankshaft to a smaller diameter.
I'm using Oliver 7.250" custom BBC rods with SBC piston pin bores in a hot street Packard V8. They are $1400 a set, but won't ever be a weak point.
As always, your engine, your money, your decision.
