any mods?

Edward  -

No mods - stock heads and cam.  I believe that the motor was bored .010 over. (it was standard bore when started).  TOE performance built the motor -

Looks good, I would love to do that one day, peak at 307.9?

  Good number as well Dave. I am guessing TOE didn't use a 5/64 x 5/64 x 3/16 ring pack and substituting a thinner set of rings ( height wise) would lessen the ring drag and "free up" some power. That is the reason I said I doubt one built from all NOS parts would make 306 hp with today's fuel.

hey Randy -

Not sure on the rings - his notes were that he used "JE Pistons, Moly" for the rings, and...  JE Pistons 4.010 bore for the Pistons...

So - NOT all NOS parts internally...

  You have good parts in there for sure. Factory production tollerences were not as tight as TOE uses and the assembly time took one tenth of the time TOE did to build it LOL!! We didn't have the quality parts back then like we do now.
