66' Barracuda and 273 with headers

66fs said
7,000 rpm is doable with stock stuff and a 273, especially with light balanced internals. Mine was a 4 speed with 340 bell and flywheel. Not sure what it would be like with a 904 auto. I ran J heads, 340 cam intake, 340 TQ, and stock exhaust manifolds, pretty sure not even close 400 hp. But was very quick. That motor would do anything I wanted depending on gearing. Rear tires will be the trick. I'm with you on the 318. Are you porting the original 66 heads? What cam?

the 273 that was in my 65 barracuda was supposed to have been rebuilt . Well ... it did not like to be revved past 6200 where I had the limiter set for a short time. well ....the rods bearing were all starved from no oil . of course don't know who built it . but on the other hand.... I had a 65 dart charger that would rev 7K all day long , but it smoked like a banchie . it was pretty loose .
