Chevrolets ZZ430 350CID engine, should I duplicate it ? Camshaft? Heads?

If you want to experiment with using the lobes from the Hot Cam in different configurations Steve Demos (Demos' Cams) has masters for them and he can grind you anything you want. I've used them quite a bit because they are quiet, easy on parts and run well.

Thank You Dave.
What does he charge for a Hyd. Roller?
No information on his web page.

Its best to just give him a call because it all depends on what core you want to use. Least expensive is to regrind a good used core from a Vortec engine.

If you look at the numbers for the heads you have, you will see that they are not "terrible". If you disassemble your heads, you should be able to clean up the pockets and guides for a good improvement in an hour or 2. Buy one of Vizards books and use it as a guide. https://www.amazon.com/Chevrolet-Small- ... 0879385472. https://www.amazon.com/David-Vizards-Cy ... 1934709646. https://www.amazon.com/Build-Performanc ... 1884089348. With the money you saved by not purchasing new heads, you can put a 383 kit in your existing block,(assuming it's not worn out), and the increase of compression and cubes will nearly double your power.

Rfoll .... and whose 383 rotating assembly are you referring to?

Your 72 cc heads and a flat top piston will give you a compression ratios in the mid 9s. More compression, more cubic inches, and add a cam to suit.
