Cams How do you choose one?
I too am getting frustrated with the low quality of hydraulics. I'd put them in but be ready to swap out 1-2 in the 1st few k miles if any of them they start leaking down too much and rattling all the time. It never used to be this way.
Going to a solid lifter cam requires changeout of the valvetrain to adjustable. And so the can 'o worms starts LOL
Thanks everyone,Howard cams got back to me with this cam lift .506/.506 duration @.050: 220/220 centreline 104. In my reading isn’t the lift over .450 to much for stock heads?
Yes, the retainers supposedly can start hitting the valve guides and seals somewhere in the .460-.480 ish range.
Even with the quick ramps of that particular Howards cam, you back to the old problem of low static CR and so you end up with poor low RPM torque when you go too big on the cam (low DCR). Know that your static CR is actually lower than 8:1. So you are digging yourself into a deeper hole in regards to low RPM torque if you cam it up.
I am in the same boat as post #12 on this. Too big of a cam for this application and starting CR is almost anything. Unless you at least mill the heads at least something like .030" to bump up the static CR, I would not cam it or only go to something like the Lunati Voodoo 10200700. At least you get a bit more lift than stock and the ramps are fast so the DCR/low RPM torque does not get hurt too bad. With this small Voodoo cam, the DCR is 7 at sea level, not much worse than stock. It'll drop to 6.4 at 3000', again not much worse than stock..... but, ow, that hurts to even think about for a cruiser LOL (Note: I refined the DCR numbers and edited them above.)
OP, any chance you would consider milling the heads to get better CR? You'll have to R&R the intake and heads and find a shop to mill them.
