318 Senior Project Build

Just remember, large cams, large ports and big valves do not option high stall converter, they REQUIRE it. And stiffer gears too. The 268 cam with around a 600-750 cfm carb (with proper jetting), and magnum heads will produce a massive horsepower gain over the stock 318 4bbl. I think it will push well over 300 horse, but tuning with the ignition timing and carb jets will be just as important to getting the most of the engine.

Alright, so if I took a stock piston replacement (Like the ones in the rebuild kit I mentioned). Bore it out .30 over, get that 268 cam, magnum heads, and tune the carb and timing I should have a decent motor? I also have a set of headers on the car too.

With this set up will I have to mill the block at all or would I just have to bore it out for the bigger pistons?

Ill be working side by side with my boss at the body shop I work at who also has many years of experience I just want to have a general idea on what I have to prepare for and what ill be doing.

Thanks for the help,
