69RR,

Although I am a drag racer, I had a similar combination... 355 with 10:1, Sportsman IIs with mild porting, Comp 294S, Weiand Team G intake and a Holly 3310 carb. The motor was a dog on the low end but came alive over 4000. I usually revved it to 6800 on motor but it would pull to 7 or more...

I have non power drums so I can't help you with the brakes...

I if your car has a 4.11 or higher and you spend most of your time in the higher reves I think the cam would be good, but if your coming off the corners at 3000 rpm then you might want to go a little lower. Just my .02.

Thanks for the input Racer Mike. I'm planning on keeping the Performer RPM manifold which means I should keep reasonable grunt from 3000 upwards, I'm not too worried about what goes on below that.

Cheers

Anyone out there with a Desktop Dyno could help me out on this one? (Sorry, I'm one of those weirdos who uses a Mac and they don't make DD for Macs)

Thanks

i need the flow numbers on the sportsmans to dyno it.

 

I have almost the same setup,355ci, 294s cam, dart iron eagle heads, performer rpm manifold, 750 holley, 11 to 1 pistons, but I have 4;56 gears in the rear end it'll get up and go when you punch it and the cam sounds really good with a pretty hard lope to it. I was really pleased with the overall performance of the cam, but then again I stay in high rpm's with a 4;56 gear but I don't ever push it past 6500 rpm's.

I've got that cam in a .060 over 327 with 461 ported heads rpm intake 750 edelbrock
9.5 compression kb pistons.It pulls hard from 2700 to 6000+.It will pull enough vac. for power brakes.

 

I'll use Iron eagles in place of your sportsmans unless you can supply with the flow numbers from your sportsmans.
right now DD2k says with the 280H cam you have:
413 HP at 6000rpms
402 TQ at 4500rpms/ 345TQ at 2000rpms

with the 294S:
442 HP at 6500rpms
419 TQ at 5000rpms/ 350TQ at 2000rpms (gain over the hydra, so gains across the band, sounds good to me)

Now i think you want a higher top end charge (4000+rpms) you should switch to a Vic JR manifold
here's the dyno pull with that:
483 HP at 6500rpms
441 TQ at 5000rpms/ 325 TQ at 2000rpms

 

Definately get a Vic Jr with that cam. That cam will want to run to 6500+
