67 Ford 390 ID numbres
 

Good Morning,

I am looking for a 67 Ford 390 to run in my Fairlane in Stock class, What are some of the ID numbers found on the Intake, heads, and block that I need to look for? Can I run a 66 block in a 1967? Help will be greatly appreciated.

Thank you
Jim

This is picked off the NHRA Engine blueprint sheet for the 390/320. Click NHRA Competition in the header of this site to find it. Or use John Scotts provided link.

67 Fairlane 390/320

intake C6AE-H ALTERNATE: C7AE-F, C6AE-G

heads C6OE-AE, AF, C7OE-E, F ,C7AE-A, C6AE-R

carb Holley C7OF-A,B,C,D ALTERNATE: HOLLEY C5AF-BD, CPAZ-U, C9AF-U

I think the block is seen as a pretty generic thing even in stock these days. Used to be everything had to be number matched by year make and model. Now any 90 degree single cam 390 block - no truck - will do.

Curious, why no 390 truck block when Chevys can run Bowties ?

If you are serious you will need to find an unmolested C6AE-H aluminum police interceptor manifold.

Also keep in mind that of all those Holley carbs listed you will want one that meets the specs for the C9AZ-U, C9AF-U, C5AF-BV carbs as it is the largest. NHRA doesn't care about having the exact OEM carb anymore, you just have to have one that has the proper throttle bore and venturi diameters. Those three carbs have the size spec'ed as 1686x1686/1375x1437 which translates to primary and secondary throttle bores of 1.686" (i.e. 1-11/16"), a primary venturi of 1.375" (1-3/8") and secondary venturi of 1.437" (1-7/16"). Those are the sizes used on all Holley 735/750/780 CFM carbs. Don't waste your time and money trying to find a 48 year old OEM carb Just get a Quickfuel SSR-780-VS and block off the secondary idle adjustment per http://www.nhra.com/userfiles/file/N...edProducts.pdf.
Life will be much easier.

A truck block may be OK. I'm pretty sure you can't run a truck engine even in GT.

Find a thick walled block by sonic checking to take advantage of the overbore rule. Edelbrock heads are allowable too.

Even if you could run a 390 Ford truck engine in S/S, I doubt that anybody would want to. Until 1975, all the pickup truck 390s were 2 barrels, and the last 2 years of 390 production,75 & 76, a 4 barrel version was available, but it was a low compession affair, with the pistons over .100" below the deck. In fact, Ford used a 410 piston in the low compression 390s, which were meant to be used with a 3.98" stroke (same as a 428) crankshaft, which explains the major deck clearance when used with a 3.78" stroke 390 crank.
