So after years of rumors about 13:1 compression, huge cam, .060 over and on and on... we find:
.030 overbore with what might be 401 (lower compression) flat top pistons
Basically stock or slightly more than stock cam
1968/69 Heads, which are outflowed by the 1970+ heads by 20-50% from what i've read. Why the 1970 heads are missing nobody knows...
So it seems when the original owner asked for "More power" out of the Calgary machine shop, they gave him a boring camshaft and less compression... and possibly someone switched heads on him while he wasn't looking. Pretty dissapointing in my eyes!
So, i am seeking the advice of Jaffray Bob, Creston Bob and whoever else might have some valuable information as to what to do next. I have a mid 70's 401 sitting here that i could use the heads from, as they are better flowing "Dog Leg" versions that were designed for unleaded gas. I could find some Edelbrock aluminum heads, and either bolt them on or have some mild porting done as recommended by some guys online. Once deciding that, i'll need to figure out what pistons to use and head gaskets. Like any daily street driver, i would like maximum streetable (and budgetable) power and the ability to run regular gas with the option of premium or better.
