Was looking in the NHRA blue print specs for the 1957 Chevrolet engines.Do not see a listing for the acceptable intake manifolds?

yes, the Chevy [57-64] posi units were the same as MoPar units, with the exception that the Chevy used 17 spline axles [just less than 1" dia.] and the MoPar posi used the larger 30 spline axles. took 4 gears to complete the swap. back in the day, the backing plates were the major hurdle. today, of course, Moser could whip out a set of much better custom axles using all Chevy parts. and yes light weight. years ago I meet a SS racer from BC,Canada who had a red '56 SS/NA with a 2x4 PG with Brake and he actually went back to the Chevy/MoPar rear. he was not easy on it.

Odd there is no list but according to note 5 the 459 is accepted.
