You may have caught my other thread about wiping a lobe. Well, once bitten, twice shy. I'm going with a different cam maker than Comp Cams. I'm down to one of the three choices in this message for a hydraulic flat tappet cam. I'm not going nuts with this build but I'd like a solid performance street motor. Which would you chose?

I would go with the Lunati Voodoo cam, designed by a pretty well know cam designer H.B. , and I would just want to tell someone I had a Voodoo cam in my motor

I'm doing the same thing. Because of this forum, I'm NOT going to use Comp Cams. I'm leaning towards the Voodoo cam also...

I ran the power-max 272 and 278 in my Vette 355 ci with 1.6 roller tips with P&P 64 cc double humps 2.02 and 2.055 intake valves. Headers and single plane.

Both of them gave me many years of enjoyment. These are true sub 13 second 1/4 mile cams.

Crane has always been good to me.

OK, next question. I am on the horns of a dillemma about the Lunati cam. I called and spoke to a rep yesterday that recommended the 60101. However, Summit is backordered on the things until 8/21 and my motor warranty on the re-build runs out on 8/25. I have no time to wait for the cam to come in and get my motor running on the street and finish checking it out before any future issues become 100% my bank account.

I was originally leaning to the 60102 cam. The two are as follows:

60101 60102 XE-268H (old cam)
Duration (0.050) Int 213 219 224
Duration (0.050) Exh 219 227 230
Lift - Int .454 .468 .477
Lift - Exh .468 .489 .480
LSA 112 112 110
LCA 108 108 106

Seems that the 60102 would compare nicely to the basic profile of the 268H but probably give a little better vaccuum due to the higher LSA. Is the 60102 going to be too much cam? Otherwise I'll have to go with a Crane just because of availability. The real deciding factor may come down to my "cruiser" 3.08 rear gearing. What do you all think?

Try Jeggs, they may have it in stock.

Isn't the Voodoo cam lobes more aggressive than the Comp XEs? If you are concerned about wiping out lobes again, I would hold off getting the Voodoo until its been around for awhile, my 2 cents.

The Crane's seem like a much better choice for a street engine. The more aggressive Lunati or Comp lobes usually enhance the lowend for a given duration. Enhanced lowend can also be had by selecting a tad bit smaller cam, which to me is an acceptable trade-off for a street engine. If you are building a max-effort engine, then use aggressive lobes with all of the supporting valve train.

Actually if you compare to the XE, the Lunati 60102 is a tad bit more mild at least on the spec card. The real reasons for going with Lunati is

a) Harold now works for Lunati, used to be lead designer for Comp....before they came out with the XE line is my understanding
b) Comp seems to have some quality control issues.....my assertion only, nothing to back that up with beyond my wiped lobe.

I hear ZERO about Crane failures and there have been enough Lunati sales now that I think we would have heard about it by already. There is a Chevelle forum that Harold participates in and I did not find one single disappointed user and a whole bunch of buyers over there because of Harold's recommendations.

For a while I was thinking of the Summit Iron heads ... and Crane PowerMax.

A question for Empatho, how is the idle quality of the lunati cam in the 383 and what part # is it, do all of the vacuum acc. work and is the car a auto or manual trans ?
I had a 383 in my 67 camaro with AFR heads on it, I used a Comp XE- 284, It sounds good and makes loads of power on the top end, but the low end is not what I expected, even with gears and a 4-speed.
I am in the process of putting this engine in a 73 corvette and want to change the cam out to tame it down for all the acc. to work with a auto and air but want good idle sound and more low end power to drive around.
As far as the lobes on the XE-284, I have had no problems with it. I have used Comp, crane, Crower and Lunati cams for the past 25 years, and never had a failure, I did all the installs at a local speed shop for years and used them all.

Thanks, Mark.

I havent istalled or fired the engine because I'm moving to california and the engine is over there and the car is in IL

Empatho

I think Dwaynes69BB is using the same cam on his 383 maybe you could pm him

I have a Crane Max Velocity 272 cam which has since been renamed Powermax. I get around 14 inches of vacuum at idle and I can idle the engine down to 700-750 rpm before it gets lumpy. It's an excellent cam with a good bottom end and power that comes on once you get past 2500 rpm. I've been running it now for at least 3 or 4 years and possibly longer with no issues at all and I highly recommend it. Here are the specs:

Part No: 113941
Grind Number HMV-272-2
Engine Ident: 1957-1987 Chevrolet V8 282 thru 400 Cu. In.
Good Idle, Daily Usage, Off Road, Highway Towing, Performance & Fuel Efficiency

Advertised Duration 272 degrees intake, 284 degrees exhaust
Duration at .050 lift 216 degrees intake, 228 degrees exhaust
Spring requirements 105 lbs. closed, 280 lbs. open
Tappet lift .454 intake, .480 exhaust with 1.5 rockers
Max lift intake 107 degrees ATDC, exhaust 117 degrees BTDC
Valve Float at 6500 rpm
