hey, I have been reading cam posts for about 2 hours. there is way too much info out there for someone who doesn't use this stuff everyday. (easy to get overloaded).

I am looking at the following as a cam for my forged 347, with Incon stage 1 turbo's. would like decent low rpm power, but having it up top would be ok too since traction will be a problem. say 3500-6800?

It is a Lunati 226/222 115. I measured the lift with a caliper, it is about .540.
will be used with yella terra 1.7's if possible.

Looking to run somewhere around 10 psi on the street and make 550-600 rwhp and turn it up at the track a few times a year and make as close to 700 as the turbo's will allow. looking at between 8.0:1 and 8.8:1 compression. Max rpm under 7000, I think. unsure about whether I want to run a stock crank.

I know this cam may not be optimal but its local, and the price is decent. Will it help or hurt me make my goals?

TIA.

that looks like a very good cam for your setup, should work well, it would be my choice for one, but maybe with a little more lift, but it aint to bad

you could use something bigger. For the Incon, I would not use a reverse split. The exhaust seems to flow well. I would use something like a 224/228 @113 with 560ish lift. Don't forget, Harlan made 600rwhp at 10 psi on the stock heads/cam. You will need a little more boost to make up for the low compression but you can make the 600 easy with pump gas. I wish I had harlans dyno sheet when he was at 10psi

rod442

Yeah, I know I can make 600 pretty easy. Probably already have done it. Just want it to be safer, with a little more head room (+100 hp ) on race gas.

Car has trapped a best of 129.5 at 3860#'s raceweight, on 11 psi and 110.

Sounds decent, I would have gone with more lift, are your heads ported?

I'd go more duration on the intake site to push the power peak up and kill some of the low end power.

6 speed is gonna need to 2 step out of the whole...I think you need to try and retain some torque down low. If I can find a deal on a stockishly small cam, I am going to slide it in place of my 231/226 115 cam and post the results.

rod442

Heads are not ported, just 6.0l's with better springs. if funds allow, I have been looking at trying to have them done when they are off the car, but I might rather put a better crank in it instead. dunno yet.

of course I have a 2 step . It does seem that maybe a bit bigger cam would be optimal, but when looking at used cams, that will be geared tword a turbo setup; there are only so many choices. especially local ones that I can drive and pick up. lol

Leave the crank alone. I wouldn't change it and don't plan to on my new setup either.
The cam is a little small especially on the lift. I think you will have a hard time hitting 700 RWHP with it. Plus I think that is about the limits of an Incon kit. You'll need upwards of 15psi to get there. But good luck.

rod442

Thanks, I didn't think it was gonna be a given I can make that much power. Just wanted to build a motor that would support all the flow the turbo's will give. drive around on 550-600, and try a bit more a couple of times a year.

ok, better off putting 1000 into the heads than a crank. good advice.

rod442

I hate to ask, but would this be a better cam than the one I listed above? its local too.

cam: 244/250 at .50,. .612/620 lift.

have to find out the lsa. also will either work with stock length pushrods and yella terra 1.7's? have to check what springs I have.

This ones not a good choice in my opinion.
