Building 1970 340 have j heads..looking for old school idle, without sacrificing vacuum, 400 hp..considering comp thumpr 279 279/297 .473/.486 .107 los (needs to be street friendly) any help greatly appreciated. Thanks Wayne:violent1:
I commented on that other thread Wayne about vacuum/pwr brakes.
I do think this cam will give you the sound you're looking for, and be very streetable, if installed at the recommended 102* CL, and make decent power.
As far as making 400hp.....that's another issue , meaning combination related...
