Anyone had any experience with the Lunati Voodoo 60203? Looks like a good solid torque cam that makes good power to 5000RPM. I have the Edlebrock 7162 in there now...........

 

I was looking at the 60202 (219/227@.05) but I think I will go with the LUN-00021 (221/233@.05). It has a 115LSA and I think that will idle better for a street car.

 

It would help if you posted the specs. If it's listed to peak at 5000 RPMs it has to be pretty mild & will have plenty of torque. Are you sure you want to go that mild? You could step up a couple of notches & make alot more power while still having more than ample torque in a bigblock.

 

That's the one I'm using in my 427. Good cam!

 

Lemansblue68 - how's the idle/vacuum? I'm assunming you have gobs of torque? Desktop dyno shows over 500 lb ft from idle to 4500.

 

Les, specs are:

Lunati: Duration 227/233 at 50 with 110 LSA Lift .542 / .554

 

It idles just rough enough to make an unknowing bystander wonder if I've got a cam in it. I never measured the vacuum but it has more than enough to operate the power brakes and vacuum accessories. I selected it with the intent of a slightly more rumpity idle and top end than stock. The stock 390 HP cam was too mild and lift numbers too low in my opinion. I originally planned to run factory exhaust manifolds and pipes but later added headers. Since the oval port Corvette intake is a bit restrictive I didn't want to go too crazy with duration for fear of killing off low end torque with a cam that favored higher RPM's which would be in turn be strangled by the intake. I think the Lunati cam I chose was a good compromise. Crane also makes a cam with similar duration numbers, a bit narrower LSA (112 I think) and a little more lift than mine, that I thought would also be good. The Voodoo cam line wasn't available when I built my motor but a couple of those grinds, one of which you mention, look interesting. I thought the LSA was a little wider than you mention, though.

I used Performance Trends Engine Analyzer when I was trying different grinds and got similar numbers to yours, i.e. gobs of torque!

 

I was thinking of a similar set up to yours, Leman Blue. I have a ~ stock 71 LS-5, but I am going to get the heads ported along with the exhaust and intake manifolds. The porting should open it up enough, plus with a 454 I believe I should be able to handle a fair bit of lift and duration. What do you guys reckon?
