I don't know the number but there is someone out there that makes a set specifically for this application. Check the Jeg's or Summit website and they'll have 'em listed. Don't know how well they fit, breathe, etc. I just know there is a set.

 

I've got Hedmans long tubes (outlets about 6 inches ahead of the crossmember) built specifically for a 65/66 with a 351. Only did some very minor tapping/flatening to get them to fit. Bought mine at Summit.

 

Here you go, you have a slight selection

Cool, would you happen to remember the part number for the long tube headers?

I see that yours is a 66' (very nice BTW) are the 66' motor mounts different from the 65'? the headers description of fit .. list - must have 66 motor mounts.

 

Its actually a 65 with mounts for a 65 with a 289....
