Need advice - potential new cam and manifold

Throw in a set of Rhoades lifters part # 2018

They will bleed down at low RPM and take some of the harshness out of the cam, and increase intake vacuum.

A smaller cam will help that also, but still consider Rhoades lifters...

I think the cam is a roller. Those 2018's will kill it. Rhoades Rollers are close to $300, Will she be good with the noise?

What's the tune up on the engine? Adequate initial timing is key with a hot camshaft. If it doesn't have at least 18*, it's not likely enough.

A smaller cam like you posted would help a lot. You could also get a core hyd roller cam and have one cut to your spec by oregon cams, bullet, comp or any number of cam shops.

Putting an rpm or air gap dual plane intake on it will help as well.
