cam selection advice

**rylie** · 02-03-2010, 01:31 PM

Hey I'm a new member and am looking for input on a cam.
I have a ls-1 i'm putting in a 69 camaro T-56 with 3:73 rearend, It'll have long tube hedders and dual exhuast. I would like a rough idle but don't want to sacrifice drivability. It's strictly a street car, not to concerned about a big increase in power. One friend mention the GM hot cam. Feedback on that cam or other suggestions would be appreciated.

sounds like the hot cam is exactly what you want bud no huge power increase but will sound very nice...

Huh. I sont think I've seen one single person in 8 years actually run a hotcam. Just call comp and let them spec u something on a 112
There r also plenty of clips of ls1s with dif cam sounds do a search. Or check youtube for g5x3 f1 ms3 228r 224r all with ls1

Any ls1 cam around 220-224 duration on a 112 or lower LSA would work just to make it rumble... You can probably pick up a used one pretty cheap, since many small cam users decide they want more power eventually.

You need to upgrade valvesprings regardless of cam, and driveability is good with a 224 cam with a tune, so why not go at least that big and get some "free" HP with your rumble!

GM ASA cam is 226/236 525/525 [109] Has a rough idle and not to much power

Yes, this is true BUT a 224R or 228R may suit him better since they have smoother idle qualities while inhabiting excellent power & driveability..............

A T-56 and those gears I think would be a perfect match with a rough asssss idle. The T-56 and gears would give the camshaft great street manners. Many tuners are familiar with this cam because its all over utube with T-56 cars. Plus you can run 570 lift LS-6 valve springs with this cam. Most people make 380-400 RWHP and close to tht in TQ.

I'd say since its a manual ust go with a 228, TSP has great packages. The 228 on a 112 lsa will give you a rougher idle and make alittle more poweer than the 224, but with a good tune will have great street manners.
I started out with a 220/224 and after driving it for a month or two I wished I would have gone bigger. Now I'm running a 238/242 but would not recomend it for a dd stock cube 346.

If your taking the heads off the motor for any reason get alittle milled off of them to bump the compression up some, its a win win mod that will give you more tq/hp, crisper throttle response, better mpg, and give a cleaner exhaust tone.

To the OP. One thing overlooked in the responses so far is how often do you mind changing springs? Some of the cams mentioned have fairly agressive lobes and may require a spring change every so often. The hotcam and ASA cams have fairly lazy lobes and you could run 100K or more between changes probably.

Check this cam out if bada$$ sound is what your looking for>>>>>> http://www.compcams.com/thumpr/default.asp

Interesting........what's the interval rate on the 224R w/918's???? Please tell me it's more than 5k-10k????

**nhraformula** · 03-11-2010, 08:06 AM

I second a 228/228 112 lsa from TSP. Great street cam that will give a nice cackle at idle

There is no set mileage number on springs, only to what you feel comfortable with. 224 that your referring to can go beyond 5-10k

There are variables like your driving style, springs used, proper installed height etc... but I would say 50k would be reasonable if you are not WOT all the time

I have much more aggressive lobes and am at 30K right now but I don't dog my car all the time either. If new heads were'nt going on soon I would be pulling a few and testing them. And the TR224 has softer more forgiving lobes than a 224r FWIW

Oh....Ok. Thanks for the info. I error on the safe side myself.....I NEVER go all out period. That's usually when something breaks........I will be thankful if I can go 50k............thanks.....

i have a comp 224 on a 112 and i love it. however i would also agree a 228 or even a 230 on a 112lsa with around a .580 lift, would really hit close to what you are wanting out of a cam.

**mark21742** · 03-11-2010, 11:16 AM

I agree with what the guys above me said. For a mostly street car daily driver I'd stay under .600", that will greatly extend your valvespring life.... To make them last longer go with titanium locks and keepers to lighten up valvetrain mass

Then you could run a nice cheap set of Comp 918s for a long time with no problems
