Steve,

Unless I missed it, you did not mention that the Texaco has a smallish intake to increase fuel draw at the lower RPMs. As to the five-fin head, some of the fellows in hotter climates may disagree with the Texaco not overheating.

My Texaco engine is a 'tweener. It has the plastic backplate and large metal tank. I believe they have since gone to a plastic tank.

For screws that keep working loose, you might try blue Lok-Tite. It lets you remove the screws easier than some other versions.

I'd like to try Texaco some day. Didn't know they went to the smaller tank.
