what des it take to stroke a 360 to 408?

Ive got a 360 with KB 10.1 pistons, oregon cam grind 474 lift, avs 750, edelbrock air gap intake,340 exhaust manifolds. i have around 4000.00 into this motor, and im not happy at all. I wish i could just start over. i just purchased a comp xe 268 cam and now i feel like i should have went bigger.


Sounds like it should be alright. What is the gear ratio? If its 2.73 no wounder your displeased, a 3.55 would be great.
If its an auto trans a 10 inch converter would be a big help also.
