A friend and I were talking about the feasability of building a high RPM (and possible boost) motor. We were thinking small stroke and big bore. If you took the crank from a 4.8 and the block from a 6.0 you would give birth to a 5.4 Is this possible and how high would you spin it? Or should we lay off the

A couple of folks have debated this in the Truck forum. The low RPM torque loss would be kinda bad in a big azz truck but a lighter vehicle might like it.
BigTex/Richard did some good research as far as the crank/piston/block offsets and sizing was concerned.
Try thread https://ls1tech.com/forums/showthrea...&highlight=327 as a starter or search the truck section using "327" or "stroker"
