Thanks for the feedback.
fstfish66 - Yes, this will be a street/strip type of setup. Already have 4-bbl carb & intake, Mallory distributor, Summit Street/Strip coil, electric fuel pump & fan. Bottom end will be stock with standard bore. Looking to add a set of 340 heads after the rebuild.
360duster - I had that feeling.
340sFastback - So, it's similar to the old & new style 350 blocks with the "spider" to hold down the lifters?
MoparAnglia - What about these cam specs: Lift: .447/.447, Duration: 291/291, Duration @ .050": 223/223, Lobe Separation: 112 LC
I'm just trying to choose a cam that will improve power and performance, but not kill it. This is my first time rebuilding a 318 engine and getting technical with improving performance cam wise.
