Header Question - 350 with 3 on the tree

[walshsta]

Hi guys, I know this is a subject that must have been covered again and again but I can’t find a definitive answer and I want to get this right the first time, I live in England so anything I buy costs me much more in duty and taxes on arrival!

So my truck is a 67 lwb fleetside, lowered 6.5/6 with spindles and springs, was an in-line 6 but now have the truck stripped down to the frame and have built a 350 that should make 375-400hp, so headers are important so that it works right. I’m using the Saginaw 3 speed, with the engine mounted in the forward V8 position with the L6 transmission crossmember moved forward.

So with all of that taken into consideration, which headers will clear my clutch and shift linkages, crossmember, and not sit too low as ground clearance is obviously not on my side!

Thanks,

Joe

Use 2.5" ramshorn manifolds, it'll save a lot of headaches from linkage, exhaust leaks, ect. There is a comparison thread on the board somewhere on how the horsepower difference is very minimal.

I don't know if we had ever come up with a definitive answer to which headers clear clutch linkage. I know the rear tube needs to drop down vertical if not slightly forward. The other question is how far down before the bend. I have had headers clear all but the one lower arm of the bell crank. I cut it off and welded to the side to make clearance.
