Camshafts and clearance

But it has to have some stuff done to it to run 7s on motor in the 1/8 in a duster street car. I know when I bought the ram charger. I heard it run and it sounded like like it has a healthy cam in it it loped nicely. I bought it just for the motor because it was a 340. I paid 150 for the whole ram charger..

Ok, if it already has a healthy sounding cam in it now and it ran 7's in the Duster what do you think you can accomplish? Sounds like it must be built pretty well now. If you want it to sound like a top fuel dragster go ahead but most likely, like others have already pointed out, you'll just slow it down and waste money doing so. If your plans are to build a stroker why not save the money and use it to make the stroker a killer engine?
