350 - 270 Combo Horsepower

[Jim Hanig]

Jim Hughes runs that engine with a stick, and runs pretty good, I think the 402 is a bit harder than the 350 . If you get the right engine builder it should be a fair engine and yes I have worked on a couple. They make about 480 or so.

Yes the 1970 402 is a way better motor. It also has an intake manifold that has a higher rise which produces better air/fuel flow than the 71 manifold. The 71 intake is flat as a pancake. The 70 engine is also 10.25-1 compression ratio. The 71 engine has a 9:28-1 CR.
