Default Cam Decisions

After it gets cold out I will be pulling the 340 out of my challenger. I need a recommendation on a cam. This is going to be a hot street, strip car with around a 3300 or 3400 stall 410 gears either rpm air gap or small single plane intake 650 mighty demon carb ported and polished X heads tti headers forged pistons and around 10.5 to 1 comp. I have a few cams in mind that seem to be around the size i want. So lets here opinions and recommendations on these cams.

Hughes 4246 .555 .569 lift 242 246 @ 50 on a 108

Racer Brown .510 lift 242 @ 50 on a 108

Comp X energy .507 .510 lift 240 246 @50 on a 110

My goal is to be in the 12's but be able to drive it on the street when i want to.

Do you have flow numbers on your heads and @200 duration numbers on the cams?

Run the Comp Cam, some dont like Comp. The state of the art cam profiles the grind on thier xtreme series makes a lot of this a non-issue.

I would buy the one recommended by racer brown, since he's an engineer and a mopar guy.

I've heard good things about hughes cams, but was turned off of them when I phoned for a recommendation, and got one without even providing a compression ratio.

Comps are state of the art, and I would definately buy one, if I had a chevy.(since that is what they are researched and ground for)

Not trying to start a flaming session, and everyone has their own opinion, but cleary this is not a non-issue.

Your right the comp i really should of put down is the one for the mopar lifter which i thought that was but here is the actual one

241 247 @ 50 .545 .545 lift on a 110

Why is it that the racer brown has so much less lift than these two cams?

The comp extreme is not ground for a chevy or the smaller lifter. The racer brown cam is just one of many profiles he grinds. The size has little to do with a head to head compare on how it will perform in it's right application where as the wrong cam will perform worse.
Just because it's smaller doesn't mean less performance.

Well said. A great headed, sorry cammed engine will always out perform the sorry headed great cammed engine. Always, when comparing cams with simular durations at .050", go with the cam that has the most lift. I am a Comp fan but that doesn't mean go with the cam with the most lift as long its Comp Cam stuff.

One other thing to look for is duration @ .200. I'll use this as tie breaker on lift vs @ .050 numbers.

I am changing cams this winter. I have a Crower 510 242@ 50 hyd. in there now. What a dog for an auto. I had 4.10 and a 2500 stall. It was a D-O-G dog! 9.75 1/8 sad for sure.
Now same cam with a 4 speed and 3.54 it runs 8.40s with a crap 2.05 60 ft.. However, Jim at R.B. knows his stuff. Thats where I'm going!!
