Picking a cam

[Z06killinSBF]

Current combo: 289 c.i. .040 bore, 9:1 forged flat tops, Isky 262 cam (.445/.445 & 208/208 @ .050, 108 LSA), stock style heads with home porting, 1.6 roller rocker, Air-Gap intake, 600 Edelbrock, 2500 stall, 3.80 gears, 2900lbs.



I am looking for something with a split profile to help out the exhaust side. Car is not a daily driver anymore and has no vacuum accessories. I have been looking at the 280H cam but have not ran any numbers on it. I am not interested in running a high price roller cam. Thanks.

With that low of compression you need to by pretty careful with the duration
I would be looking at something like the Crower 280HDP
The split pattern will work well with your poor flowing stock-ish exhaust and the wider 112LS will keep the power at low RPM in the little 289

Yea, the heads are a 64cc combustion chamber vs the original 54cc's. So my comp dropped a lot. I know I need a good set of heads but was curious if there was anything to gain over my current combo.

I like dual profile cams.

Extreme energy Comp Cams are nice, and have the sound.

Comp Cams has recently added a Thumpr line that has sound, botom end and vacuum.

I would go to a couple of profiles larger than what you have, and step to a 1.7 rocker.

Another option is to use a bigger cam, and make sure it's a nitrous or blower profile. This wil spread the LCA and retain some compression through reduction of overlap.
