I know I should be looking for a lobe separation of 112 to 114.

But can I get a 110 Separation to work with a good tune. (Lunati 60122)

SLP runners and Eldenbrok Hi flow base.

It will also be in a 383.

The RPM range is 2400 to 6200 What I was told the 383 will put the RPM range down lower so this might just miter work out for the 383 DD street motor.

What your 2 cents on this.

The short answer is yes. Lobe seperation means nothing with considering all the other aspects of the camshaft. It can be made to work fine.

FYI, That cam is pretty big for a long runner TPI style of system, it can work but may not be the best choice for your application.

Hum Ok I just to want to make sure I get the right cam this time around before other were saying I was using to small of a cxam with my set up and the 195 Heads.

And a 383 needs a bigger cam.

Honestly I think that Lunati is too big for a TPI.

You need to look at something about 10* smaller (advertised and @.050).

Honestly I think the GM hot cam or something along those lines would be a good choice for what your doing.

Impressive numbers don't mean crap when it comes to a choked up TPI intake system.

Your engine won't make any power over 5500RPM - no matter what cam you stick in it.

All a bigger cam does is narrow the powerband from the bottom up. Since you can't do anything about the top end (without buying an entirely different intake manifold) why give up what could have on the bottom end?

I have a new XE256 cam on 110 lsa that I am going to put in my 85. I have tuning capability....but little knowledge. Sounds like a good cam to learn on.

I have an Erson 218/ 226 / 112 LS in my 383 which is real close to the Hot cam. I have to agree with rklessdriver about this being a real good choice for the 383 motor when using a TPI intake, which I also have, Edelbrock base, Accel runners, ported plenum.....This was the cam Pete K suggested for my build after talking with the Erson tech. There's no sense having a cam for high rpms when the best your motor will do before its out of breath is 5500 rpms.....WW

After looking at all the pros and cons I going to keep my Lunati 60101 cam I can't see forking out a extra $600.00+ to swap to a roller after all.

The OP range of my cam now seems to be the best from what I want it to do and has the number I like for a DD and still has a mean sound to it not a full race car sound.

With the intake and smog what I have seems to be the best combo for now at least untill they do away with smoging my Car out here in Cal.

I can buy a lot of zinc for oil change with the $600.00+ up front I be saving LOL.

This is my cam and I going to use And power numbers.

Not all heads are equal. Some heads don't "need" as much cam to produce the output. Plus, there are other solid roller cams out there.

I wanted that Voodoo for awhile......I researched it for a long time, and it has a rep as an excellent TPI cam. And yes, you can buy a lot of zinc for the cost of a retro roller setup. Almost cheaper to get a late model roller block with a cam already in it lol

I went with the Crane cams TPI cam, P.N. 104224 in my 383.
With 1.6 roller rockers it is .482 in. and .495 ex.
above 1700 RPM, the aceleration takes your breath away.
on the mileage indicator, I get 19 avg, and 29-32 straight and level.
It has a slight lope to it and sounds "healthy".
On my 350 TPI, I went with the marine cam. It is the same cam Chevy uses on the ram jet 350 and the HT 383 truck engine.
THe 350 pulls hard right off idle and the 383 has to get some RPM. Both cams are full rollers.
I found the cam on Fleabay for $35 as a take out cam. It apparently never was in a running engine because the lobes didn't look like they had any roller marks, just the polished machine finish.
THe same guy sells all kinds of cams. I get the idea that he works for a dealer and they just discard the cams and he makes a little on the side.

It cost me $200.00 for everything after returning my Lunati cam set up.

I end up getting a LT4 GM hot Cam, Used Spider set up, New CC timing chain and gears that I can use with my 2 PC timing cover OEM Hyd roller lifters, CC push rods.

I have read this will pass CA Smog with a good tune.
