I am going to build a 426 hemi for a friend. He purchased a new hemi block in 1994 which has both hemi and "440" mounting lugs on it. He prefers to use the "440" mounts since he does not have a hemi K-member. He has chassis headers (hemi) for it also.

My question is this: Will the chassis headers work (clear) on this engine using the 440 mounts? It is going in a 70 Cuda. I am sure someone out there has dealt with this situation.

PM me or dodgeboy69@atlanticbb.net

Thanks,

the easy thing to do would buy the schumaker mounts for it to convert it from 440-Hemi. Thats what we did with a 69 coronet and are going to be doing with a 383 Road Runner. both with under body headers. show cars to boot.

The headers will clear on the passenger side but I have heard they will not clear the mount on the drivers side.

Look in arruzza's web site. He sells some nice looking hemi mounts. I have not tried them.

Most Headers will not clear the 440 mounting on the drivers side.
You can buy the custom headers intended for this or, grind off the tabs on the block and use the Hemi mounts with the correct brackets and special K frame..

I talked to a guy who did just what you describe, he said he had to grind a bit on the one mounting lug for clearance and ding a header tube a little.

I used the Arruzza mounts on my 70 cuda hemi crate motor and had zero issues with engine position and TTI header fitment.Good luck!
