more info >> inside of engine was clean as a whistle I think it was barely run before parked 25 years ago. had 675 heads on it and a big Crane solid in it, ld340 dual plane on it and a 600eddy.. it was pouring oil out the back of intake , bad rear gasket . went to fix that and found the cam had two lobes worn down on it. so I had another 67 273 engine that had a bad rod with good 920 closed chamber heads and the erson 286 dur 510 lift cam went in as mentioned. That all was installed along with the solid lifters. and adjustable rocker gear. along with the .023 thin head gaskets . ending up with a tweaked holley 650 dp carb on top that combo . still has stock point dist .changing that at some point . been running great all summer. has 8 3/4 rear with 3:55 gear , quite , nice shifting stock 4 speed and diaphram clutch that is tired. It is a AC car as well. I removed all of the AC components off the engine for now .
ps : been told by several people that the barracuda sounds like a big block.
