318 build check from you experts

I call BS and my favorite 318 hater is back I see. Instead of helping you with what ya got, he’s asking you to spend more money. Not that a larger engine is a good route, but why stop at a 5.9 and go right to the top with a stroked 400/440?

Let’s get to the serious part of this and start with your cam. It is a Comp 252 advertised duration with .425 lift. This is barely the first step above a stock cam and waaaaay smaller than the OE 340/360 performance cam.
WAY SMALLER!

It is not to much for the stock heads. Just use the recommended spring from Comp or an equal. Keep the stock heads. Aluminum would be a waste of money and so would 1.6 rockers. Just reuse the factory rocker.

Use those 9.5-1 pistons! Measure them in the bore on how far down they are along with the cylinder head cc amount. Then the gasket size. Thickness and bore.

Go here and enter the numbers for hour static ratio.

Remember your can use a thicker gasket to lower or thinner to raise the compression. 9.5-1 actual or lower is good.
I would certainly use the 650 carb on top of the rpm.

On a converter, I’d bet a G that the stock converter will work perfectly but you’ll need to know the gears & the tire size along with all the engine stuff. So write that down when you call up a custom converter place like Dynamic, Pro Torque, Ultimate, etc...
