Low money 360 any ideas
Focus on the converter. Get a decent cam then call a converter company and tell them the specs and rear gear and other details.
If I was in your shoes I would work over the heads.
Then get a rpm intake and one of the mild summit cams. Throw a 750 dp on top and be done with the motor. Then the right converter for your combo and some 4:11 gears and then have fun!
Just saw your last post so you seem to be ready!
