Joedust, I don't want to be offensive and you have a nice running combo but
Its a 340 he's asking about. You can't really compare a 340 to a 451. The 340 is much more sensitive to cam size. They make good horsepower but the torque has to come from gears and higher converter. A 340 with a 285 cam is gonna want to shift at 6800rpm as well.



Yeah i wasn't paying attention LOL, Ok then, I think the cam will still work fine & be streetable in the 340, I would go with at least a true 10.1 too 10.5, 43-4500 stall & at least a 4.30 gear. Aluminum heads at least 10.8
