Hi, I have a Dodge Dart with 360 LA engine, but with magnum heads.
The intake is mopar M1 magnum, and the rocker arms in the magnum heads are roller, with 1.7 rocker ratio.
The camshaft is a sollid flat tapped Mopar 296/296 (557 lift). The problem is that the car is very heavy (3550 lbs), and I think that the camshaft isn't good for this combo, because the 1.7 rocker arms, and the engine now is very radical...The engine goes to 7000 rpm quickly (4 speed manual gears), but is very difficult drive the car in the city. I have a fried that has the same camshaft, but with 1.5 roller rockers, and his car is more civilized, more enjoyable, and runs as fast as my.
What do you suggest, please, change the camshaft? Change the rocker arms? I was thinking about the 282 XS comp cams (282/290, lift 520/540). Thank you.
