    CL35-601-8 - Comp Cams Thumpr Hydraulic Roller Cams is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Sounds like a real hotrod now!! After having two flat tappet cam of the same company go flat during the first 20min of breakin, i realize this is the way to go . It’s cheaper to go roller the first time then rebuilding your engine three time . There is no valvetrain noise , those lifter seem to be really good quality. I have been watching a lots of video on YouTube of thumpr cam and most of the time the are not tune right ... you need to have lots of initial timing and limit your total to 36 degree and have your idle set to at least 1100rpm . My 357windsor is at 10.25 to 1 compression and i have 10” 3500stall converter it seem to idle good a 1200rpm with 26 degree initial timing , may need more will check with vacuum gauge when I have more time . I have not check the vacuum yet but I seem low for my brake booster. I would recommend this cam combo, I really like the sound , even revving the engine to 2000rpm you can still ear the chop from the cam , sounds really mean
