Cam ID

ok YOU HAVE
a stock low compression 318
stock converter, stock gears
cam without the matching lifters
so you can get new lifters and run that cam but no advantage over the stock cam that's in it now
Change the timing chain and be happy
or
you could change to the 250 luanti voodoo or 256 Howard that's bout it
both these close the intake at about the same time because the Howard has closer lobe centers than the Lunati and would give you slightly more rump d rump
any more you will have performance around town and mileage that sucks
want noise change your muffler or slow down the idle
I'd think about new springs with either of these two cams or any cam change
you can change them in the car and new stem seals
do a compression test and post back
make sure you are not due for a valve job
