Which of these Cams?

Ive finally decided between these two cams. Im looking to improve the performance on a car that is somewhat of a daily driver. The cam has to work with the stock computer also. Which of these two will be better for me? Will the motor be able to handle the lift of these cams? Will either of these cams give the motor a rougher idle?

Re: Which of these Cams?

I'd probably try the split cam.

Anybody else b/c I'm not EFI guy at all.

Re: Which of these Cams?

How would the idle be with these cams? Would it be a noticeable idle or a smooth idle?

A 260 will have a hint of cackle to it, imho.

Re: Which of these Cams?

The split duration if you want more chance of hearing it. It also has teeny bit tighter LSA so with the extra exhaust duration and the tighter lsa you get more overlap which is what causes the cackle. The cackle we love so much is actually the engine not running worth a ****

Idunno on the computer end, but the single pattern says 350/TPI in the description down to the bottom area.

Is this a 305 engine?

Re: Which of these Cams?

Please get into the cam e-cats and look in the Computer Compatable Cam sections and compare several from different companies b/c this get's a little may I say, "touchy" b/c of the brain..

I know Crane has their line of CompuCams and I'm sure CC does too as does Crower w/ their "several levels" list of cams..

Sure don't want to steer you wrong here is all. Best ta do the homework before dropping the dime, imho..

You need a cam that is compatable w/ the brain, not one that SOUND'S NICE!!

This is why I'm advising you to DO YOUR HOMEWORK!

A "cackling" cam will screw a brain up big-time b/c it's not sucking properly ALL the time!!

Sure, it will be fine once it's "up on the pipe" as the 2-stroke guys say, but you will still need to idle around and that's where you can get in trouble the LITTLE I know about brains...

I'm strictly a carb. guy.

You want "cackle", pull a sparkplug wire off and ride the brakes!! Then after you get finished going around Burger King, stop and put the plug wire back on and go home!!

Been there, done that......

LMAO pdq.

You need Chris Straub to come tell you a cam or at least somebody who has done a ecm'd cam job. I never fooled with a cam in a pewterized engine.

Re: Which of these Cams?

Computer cams are generally under 220°@.050" and have more than 114° LSA or more, single pattern.

Vacuum has to be high so the MAP sensor sends a higher signal and the ECM reads it as a high vacuum and the fuel map runs accordingly, hence, a smooth running engine.

Call the cam company for a more precise selection. Otherwise, you're looking into reprogrammed chip or a programmable aftermarket ECM.

Re: Which of these Cams?

I am not looking to have a "cackling" cam. I want it to still sound close to a stock idle. How would the computer react to the 112 LSA?
