Re: 383
234/238 @50 duration of that cam is ballpark with what most are running in good 383's
with 195/ 200 heads.
Depending what the heads flow you might use some more lift (1.6 rockers )
Comp 08-467-8 cam is a popular 383 cam
230/ 236 but with 570 /576 lift
with 195/ 200 heads.

Re: 383

Re: 383
dont need to change anything else. the 1.6 rockers give you roughly a .03 boost in lift over 1.5 rockers. you just need to double check that your heads can handle that extra lift without contact issues. and the check that the springs can handle the lift before coil bind.
