Ok so i have a project truck that i have been working on for a friend. Its an 87 Dodge W150 w/318cid. So brief history on motor... I took out the original 318 and put in a 318 that he had from a 74 but wanted me to go thru it. So we punched it out 0.060 put in a bigger cam w/ .484 lift and .282 duration took heads down .010 had to shave valve guides to accept the cam lift. Has edelbrock 750 carb (freshly rebuilt) on edelbrock performer intake.....k so my problem...is this dam thing has a "flat spot" on heavy acceleration. So was thinking the distributor i used was for the original motor (87) and we put 74 motor. So bought a new dist. W/ vacuum advance installed retimed and flat spot persists..any ideas???
