Inliners International Forums General Discussion Engines A bit more power for a stock '76 250

If the integrated head is as bad as it sounds on this forum, maybe I’ll look for an earlier head.

Regarding the intake, what are the main differences between the Clifford and the Offenhauser? If I wanted to go with a Holley Weber 5200, which Offenhauser intake should I use?

My goals are the following:

Just enough power gain for easier passing and lower RPMs on the highway going 65-75.

At least a few MPG gain.

Smooth idle, (not fair idle, not okay idle, SMOOTH IDLE).

Thanks in advance.
