Modified questions

[RPM5595]

Ah, I see. Another gentleman on the S/SS board says I can not run aftermarket heads, Ford OEM only, so now I'm really confused. He mentions the GM guys can use certain Bowtie parts though so I wonder if any Ford Racing parts would be acceptable? I'm just going to have to bite the bullet and contact NHRA I imagine. Thanks for your help.

I asked NHRA the same question a couple of years age. I can't remember the exact answer but they did consider FRP heads to be OEM and legal.

But do ask NHRA because rule interpretations seem to change over time.

Thanks, a call to NHRA is in order.

Any update?

[davyjones]

it must have a part number from the orginal equipment manufacturer. Like you see on parts in the ford , chevy , chrystler racing catalogs .

I have never seen a brodix head or a dart block in any comp or modifed car .

I have the part about needing to be a Ford or Ford Racing part confirmed. I am now trying to find any information about the Ford Racing M-6049-V351 head. It shows it is available but gives no information about it. Any insights?

Thanks, Jay

When I asked they said the N351 was legal but there was no V351 in the catalog at that time. What is the V351 head? Is it a cast iron or an aluminum head.

I think the N351 head would be very good for a class requiring cast iron, it doesn't show the flow numbers of some other heads but makes horsepower beyond the flow numbers.

In classes using aluminum heads the Z304 can make some good HP.
