i really hope this 383 of mine makes 500hp @ the engine. with decent headers i'd like to see 540ish. with a cam change i'm sure there's abit more there. i do have access to a mushroom lifter mini express cam but then i'd need all the other stuff to go with it. cash is the cork in my build. if a solid cam would make a decent jump in performence i'd swap the old mopar one out, as i used the mopar one as a good base line because it's so hard to find good info about 383 builds specialy with ez heads. i haven't found any info about that combo. in my head i'm thinking less cubes & short stroke = less wheel spin & what we lack down low we'll make up top. i'm very tempted to build another race 383 or 400 long rod motor & rev it to the moon . but that screams aftermarket block & weight loss.
