273????

As a compromise, rather than rebuild my worn out 273,
or going to a 340/360 and then having to worry about the tranny breaking;
I built a 318.

Stock compression 1974 era engine.
# 302 heads milled only to cleanup,
Ld4B intake small ports keep the velocity high,
Edelbrock # 1406 carb electric choke 600 cfm "Afb"
.430/.450 Mopar cam with Mopar lifters, and New valve springs
dual exhaust off the stock 273 manifolds,
2.25" system, Dynomax Super Turbos.

I am happy with the setup, the cam is about the biggest I would use,
in a 318 with 2.93 gears.
