Idle with this came

I bought a Lunati Cam part number 00010LK

Just curious at how the idle will be on this? 2000-6000 is the power range. Thanks

Has a moderate rough idle with reduced intake manifold vacuum at idle.
You'll want to recurve the distributor for more initial timing at idle, but same 34-36deg at high rpm. (limit mechanical advance travel from 20 to about 12-16)
allowing 20 to 24 deg at idle.

Power brakes should work ok. If you have trouble with them add a vacuum reseviour canistor. (increased capacity) Needs more than stock compression ratio 10:1 best 8.5:1 will not cut it.

will work just ok with a stock converter (2100 stall) {you'll get by} but don't expect to be set in your seat.
really needs a 3500stall. 3.73 minimum gears. 4.10's best ,,needs headers and dual exhaust.
head porting will definatly help. use a vic JR or Perf RPM and 750cfm carb.

If you don;t have close to these other parts you probabily picked the wrong cam. use lunati #73943 springs.
Can work very well for ya if combined with the rest of the
recipe.
