A member contacted me. He has a 300, .060 over, over-size valves, p&p head, Comp 252 cam, oem int/exh., 273(?) rears, with OD trans, and he gets 20--22 mpg on the freeway! He said he tach's 2k cruising.

I like that. (Kind of like AB @ 80mph!).

 

Thats real good, is that with stock sized tires and everything?

 

Aside from the oversize valves, that's similar to my van 300, and I'm getting 16-18 cruising at 70 on the freeway without OD. That 252 grind is great for mid range power and makes a very wide sweet spot for economical cruising.

 

31" tires.

 

Weld all thread fittings. You'll be glad you did. It's also a good idea to weld a bead around the end of each pipe, so the hose doesn't slide off.

 

Ok, Whats are we looking at here??? did u accidentally post this here instead of your plumbing forum???

 

Sorry guys. The member who is getting 22mpg asked about using a Offenhauser intake, and wanted to know about the heating plate needed for the bottom of them. I posted that so he could see what I made for the plate, to get coolant to the spot.

 

Tell him to sign up here! I wanna hear more about his ride. Pictures would be great too.

 

Sounds great! Money spent on the head a valves are a good investment even on an otherwise stock engine.
