Mild "budget" 350 cam ... suggestions

I'm putting together a mild .060 over 350, that's going into a '70 El Camino, that will be sold. 8.5-9 to 1 (probably closer to 8.5), 882 heads, headers, Performer manifold, 1850 Holly. Vehicle will have a 3.36 rear end, and a stock converter. The CC 260 ,12-206 cam, ( 260/260, 212/212, .440/.440, 110, 1200-5200, .... and lifters have met their life expectancy, judging by the very noticable concave surfaces of the lifters.

As noted, this a budget, and also unplanned, rebuild. I'm hoping to find a cost effective cam with similar characteristics, from a source other than the highly promoted cam companies. Any suggestions? Thanks

Work in progress:

- 540 /325 AFR's / HR cam
- 4L80E

you can get the Elgin copy of the crane 274HO6 from several places for about $100 for cam and lifters. with the 106LSA it will have a nice choppy idle. might help the sale if it sounds hotter than it really is.

Good advice right there. Elgin cam/lifter kit, part # E1785PM. It's $113.95 at Competition Products. Also sold under Summit Racing part # SUM-K00172 for a little more.

northern has it for $99 cam/lifters but with shipping to me at least ends up being about $115. The summit cam hferris linked to would be good also.

Re: Mild "budget" 350 cam ... suggestions

are the heads off?
if so, get a GMPP shim head gasket in there, build a tad more compression.
Then cams should have a little advance ground into them. Consider advancing the cam a tad more for more low end power

Yeah, I've thought of that and I like the idea. It's evident that the block has been decked, at some point, but that was before I acquired it, 25 + years ago. Maybe it's still straight. Block is at the machine shop currently, ... I'll have them check it for straightness. The heads going on it, have been surfaced, but not milled. What's the part number of the GMPP gasket you're referring to?

Not sure wht the specs were, but the 300hp 327 cam worked pretty well in a mild 350.

Re: Mild "budget" 350 cam ... suggestions

I still have not yet decided on a cam. Maybe a few more specifics would help. Given my combo, what would be the most duration allowable, ... that still produces good vacuum, and works with a stock converter? Think I'll end up at 9 to 1 after all. Thanks

Re: Mild "budget" 350 cam ... suggestions

My high school DD had a 350 w/specs like yours. I put a Crane Fireball 290 in it, had a great sound and lots of low end TQ. It was .454" lift I/E, 216*/216* duration and110 LSA.

It looks to have been replaced with the Energizer 272.

Re: Mild "budget" 350 cam ... suggestions

Major cam company, and specifically the same one you're using now, but may I've talked to have told me the Comp Cams 268AH-10 is a great street cam for a mild 350. Not to be confused with the standard single-pattern 268H.

http://www.summitracing.com/parts/CCA-12-318-4/

222/226 268/276 .464/.464 110LSA

There's also the 260AH-10 which is closer in size to your current cam, with a little more exhaust duration.

http://www.summitracing.com/parts/CCA-12-312-4/

212/218 260/268 .444/.444

Change the -10 to a -8 on either cam to get it on 108LSA for a little more lumpy idle and light-switch-like-response when it gets into its groove.

Re: Mild "budget" 350 cam ... suggestions

This "budget" cam caught my eye. Lunati Bare Bones 10001lk. Description is: Good idle for daily usage or towing, Good low end and mid range. 1500-5000, .443/.465, 214/224, 280/290, 112/107 LSA. It appears that this combination of lifts, durations, and LSA's produce, a friendly cam. However, the longer durations, have me wondering. Any thoughts? Thanks
