Re: [FWDLK] 315 vs 325??

[Eastern Sierra Adjustment Svc <esierraadj@xxxxxxxxxxx>]

Dave Homstad can jump in with all the differences, but the major one
regarding the 260 HP (IIRC) 315 56 Hemi was its solid valve lifters , 
which require adjustment, etc.

The 285 HP 57 325 Hemi has maintenance free hydraulic valve lifters.

Besides the engine stampings  (D500-1xxx , and KD500-1xxx)  the 56 
engine has a large metal
brace that supports the oil filler tube;  57 just has a  free standing 
oil filler tube.

Gotta get back to work, now...
