will this cam work well?

i have a 69 suburban with a 350 from an 88 1500 truck, a th350 tranny, stock converter(dont know stall). holley street doninator intake, holley 600cfm vacumn secondary carb, short headers.

the cam i am thinking of using is the crane version of the chevy 327/350hp cam. crn-967601. 222* duration in/ex. .447" lift in/ex. and i think 114* lobe seperation.

the truck is just a driver. do you think this will give me good midrange. would 1.6 or 1.7 rockers help or hurt?

thanks

If you pull 10* off the duration, you can pull 4* off the LSA, and make better low-mid torque,

but some people will disagree and want to make it a 5200 pound race truck.

I'd go for a 208* or a 212* on 110* LSA.

The camyou suggest will put your power peaks up at 4000 and 5600.

Here's a very good, proven cam for applications just like yours. I have used this cam in dozens of engines and have never had a complaint. It is marketed under many brand names.
Specs are 204 @ .050 in. and 214 @ .050 ex.
.420 lift in. and .443 lift ex. with 112 of lobe sep.
It has a great idle and makes lots of torque.

Good luck with your project and welcome.

Barry

I agree 100%! The 350hp/327 cam is not for your application.

Get the performer cam (not performer plus or performer rpm) or get the summit cam of similar duration.

Yes, 204/214 degrees duration is what you need for a multitude of reasons. (low compression, poor flowing exhaust port, stock valve springs, stock rockers, small engine in a heavy truck)

There has been an influx of poor quality off shore lifters that are blamed for cam failures. Consider what you might be buying at bargain basement prices.

Agree with everything said above....... I know of 2 people that have used the Summit 1102 in large vehicles with high gears and relatively small displacement and it worked great.
One was a '63 Bel Air with a boneyard 305, 200-4R and 3.08's. It was no tire shredder but it could haul 4 adults no problem and got an easy 20 MPG doing it.

Just FTR, they had no problems with the Summit lifters but yes, there is some crap out there so do be careful.
