Thread: 351 W knowledge needed

Tweet

Last year at the Goodguys show in Joliet a guy had a Walker for $200 for a 37 used it in mock up at his shop . Hadn't quite made the deal yet so I passed on Rad .

Not a real fan on aluminum heads either and there are some good worked iron ones out there from shops . Don't take much of a overheat on one to take it out of commission . My thoughts as always has been a nostalgia build not on 1/4 mile .

I also have read a lot of bench porting about these SBF heads . Safe sizes for the bowls and water jacket locations . Things to help them breath just a bit more and I would not be afraid to get out the carbide by no means .

Not worried about bragging rights just a nice cruiser with some effects is all . A 351 stock alone will pull this car great we know that much . I thought about that 85hp in there maybe twisting the frame from its earlier launches . But I am no launcher just a cruiser .

Bobby - about the only thing I would do to those heads is straighten out the intake side to fit the gasket to reduce the projection into the gas path and if the exhaust has an EGR bump, flatten that to blend with the rest of the runner, and of course, clean up to a gasket dimensions. Anything else - a waste of time and if you get into the valve pocket, even more reduction of what little compression ratio those 69cc heads have.

About all an 85Hp flattie could launch is that fragile OEM tranny - and that usually by "speed" shifting (and they were a b@#$% to change out with that torque tube - {why do I know that - maybe by some scar tissue on some fingers} )

Dave I will most likely run these stock till something comes along . Or if I find something before it begins .

If you could manage to trip over a pair of GT-40 heads they make decent power, too.... Even came on some of the Explorers....

Dave I know of those and hope the U pick have them before someone else finds them . The P heads seem to be limited to exhaust but the GT 40 would be a great selection .

I have the GT40P heads on my 302. I got them from an '01 Explorer. Sanderson makes blockhugger headers to fit them. Looks like this:

Or ---- the GT40P's they could look like this fully 'dressed'. The combustion chamber is 65.5cc so is somewhat better with the valve size the same as the "good" OEM '69-'74s.
