1967 Ford 390

Rich67stang · 04-21-2014, 08:56 PM

I just picked up a 1967 Mustang that I want to build a D/SA. I have a few questions, and appreciate any advise.
1. Must be an Original Block?(Do NHRA/IHRA have approved aftermarket)
2. Must be Original Crank? (Do NHRA/IHRA have approved aftermarket)
3. What intake is allowed?(Do NHRA/IHRA have approved aftermarket)
4. I know NHRA/IHRA approved the Edelbrock heads, Can I use aftermarket rockers with Studs?

I built an IHRA Crate motor car, I was going to build a 1993 Cobra, I decided on a 67 Mustang to match my superstocker...

Thanks

No you don't have to use the original block or crank. You can use a Aluminum police interceptor Intake. You can also use roller rockers. Look under the NHRA comp.web page. It will give the updated and legal parts.CC's, replacement PARTS.ETC.

What Chris said and in my opinion do yourself a favor and give Blair Patrick a call 423-837-1514.

Go through this link to see what's already approved for that engine. You can ask to have a crank approved by submitting a form on this page. There are several standard weight forged cranks for the 390. Make sure the rod length is stock.

4 speed was not available in a Factory built car until 1962. You could buy one over the parts counter in 1961 (T10 BW) along with 3 duce set up and it was NHRA Legal.

There are, NO after market cranks readily available for the 390-427 I am aware of at this time. You can modify a 391 crank (expensive $1500) or have a Specialty Crank Company build you one (more expensive $2500 min) All aftermarket cranks are for Stroker combo's and not Legal for 390-427 OEM stroke application for S/SS.

A cast crank is not only lighter, it can handle most any S/SS application. I have been running 390's for over 20 years and have never had a problem with the strength of a cast 390 crank if done correctly.

If you need a 427 crank just grove the mains of a 390 crank, and don't forget to grind the pin to 2.200 from the not so popular 2.437 stock size.
