I just stroked out my 350 to a 383 added 210 cansfield heads ported to 1206 felpro with mini ram and lpe headers. I just have one more need, a good cam to run with this set up. I was looking at comp cam's magnum cam summit catalog cca-12-212-2. If I get this will my 1991 lifter work with this or will I have to buy new lifters? I am trying to stay under 350.00 for cam set up any other ideas please let me know.

You need to provide more info. Is this a street car? A drag car or a race car. What the tranny , torque converter stall speed and rear end gears?

 

From what I've seen their extreme lift 224/230 didn't provide enough idle for me. So I custom ordered a 114 lobe seperatio CAM. I'd go with single pattern since you have the exhuast to back your intake up. a 224/224 on 112 would give a 0 degree overlap. Keep in mind that the lPE recommended cam is a 219/219.

cheers

 

That's exacty what I did. I ordered their 3192 intake lobe and 3315 exhaust lobe ground on 114 with zero advance ground in. It's 224/230@.050 It pulls 14 inches of vacuum and I;ve got my PROM burned for it to idle at 850.

I want a street/strip and I have stock converter and 3.54 dana 44 auto.

 

I really think you need to get some overlap in a cam if you intend on doing any exhuast scavaging and making any power, especailly on a 383.

If you want it to be street friendly- high lift, strong valvetrain.

stock converter is a bad idea.

 

I was thinking of the tps zz9. pro's cons and a change in torque converter . 225/240 lob @.5 .520/.558 lob 112. Do you guys think this might work ?

How do you figure that would give a 0 deg overlap :skep: . Talk to the pros at comp, crane, lunati.....etc. See what they recomend and go from there.

 

so the canfields have spark plug angle compatible with the headers?

Emissions is not a concern I'm assuming.

For a short while I ran a comp cam 242/248 on a 110 LSA. The power band was way up there! I was so used to it down low for around town driving. Plus idle was rough. It would hunt. (but I wanted a choppy lopey idle)
It screamed up top. It was just too much duration for me. It's out now.

I would suggest as others, around 112 LSA just because of vacuum. The 110 I had, I would get very low vacuum and brakes would not be there when I needed them.

some points Id like to disagree with here.

durration- probobly not a good idea to go big here on stock manifolds and stock heads and such. perhaps a longer exhuast durration, but certainly not intake.

112 LSA WILL have overlap if i am not mistaken.

You can not go big with a cam on these heads and exhuast.
with cast heads, your velocity will be poor and you will have nothing but reversion down low whilie the heads can not support high RPMs and bam- your left with the worst of both worlds.

Wider LSA? I dare question why. He NEEDS exhuast scavaging- 100%. He is running an NA setup with poor exhuast. Overlap is a must for this guy!

I suggest short durration, tight LSA, wide exhuast, relativly high lift...
keep it tame, powerful, exciting.
I would hardly call comp and those guys "experts." Well as far as the LT1 is concerned, might be different with TPI setups. a lot of these so called "experts" seem to be flukes. TPIS told many that the hotcam is too big for a 350ci motor. Although I agree its a craptastic cam- its hardly too big. It doesn't do much too well and for the same "price" you pay in idle quality and gas milage- you can have much more power. the lift on that cam is a big concern IMHO. I'm not going to suggest a particular cam, but again respectfully disagree with some of the opinions here.

Call up Combination motorsports cmotorsports.com.. they should set you strait!
Just my highly opinionated .02
(christ, i'm beinging to sound like someone i dont want to :lol: )
