budget street motor 360 or 383 for 71 duster

Ok have you guys ever had a 383? Or had a mild or built 383? More torque and less money to get to 400-500 hp. I though he was on a budget of 4-5k. You dont not need a stroker kit or aluminum heads to get 400-475 hp out of a 383. 400-475 hp out of a 360 will take way more money. A little heavier in the front but not much. His suspension will be fine as is. Now dump the LA 360 for a 360 magnum I may go that route.

but figure in the cost of the 727 and converter to fit the 383......and the performance hit on the 727,,,,...dont know what he has now but assuming it is a904.....
