I picked the lunati voodoo for my similar build. I am going with the 213/220 version for a true street car with low compression Lunati 10100701. I have used the 226 duration version in higher compression engines 10100703. Also using the 226 duration in a low-ish compression street strip car which will have aggressive gearing and a healthy converter so the low compression won't be an issue with the healthy cam.
But you can't go wrong with the small Summit cam. Summit 8600. I have run mid to high 12s with that cam in an otherwise stock 360 |

what ever you do, you have to make sure you have sufficient retainer to guide clearance with any cam for amc. I mention because the cams above are significantly higher lift than stock.
Second thing to caution you on, beware that most all of the timing chain sets out there have either the oil feed notch for the distributor gear oiling passage in the wrong place or egregious ginormous slots on the aft face of the timing gear that bleed off all of the oil. Or both. |

Call Mike Jones, tell him your specs, weight, tranny, axle ratio, etc., and you'll be happy with what he devises. My 343 is now 365, same displacement as yours will be. I also did not want a racing cam because I have no use for a car that looks fast but is a dog under 4000rpm. I went with 9.24 compression when I ordered my custom pistons to ensure I can run pump gas. The motor is blueprinted and uses very good parts so I'll never destroy it within its RPM range, but it's not a race motor. I might have the tiniest custom hydraulic cam of anyone I know, just 202/208, but it made 363HP and 417TQ. That was with an Edelbrock carb and overly rich AFR. The Q-650 racing carb on there now with the AFR tuned leaner has to be at least 25 better than those numbers based on my runs and stress on my cervical vertebrae when hitting the gas pedal.
Jones and his old man used to make cams for Indy cars, and he's also a genius with small cams. I don't have anything against Lunati or any of those old school grinds from the 60s or 70s, but technology has changed a lot in the last half-century. Jones' cams make more power AND vacuum for their duration than the archaic grinds (but are not as lopey if sounding tough is more important than streetable power), and the ones he makes for street cars are especially easy on the valvetrain and last a long time. My motor sounds fairly powerful, but almost as smooth as a stock motor, and it still revs to 5500 very fast. A hydraulic cam will cost you about $250 and the lifters he uses aren't cheap either, but that's still a bargain for the quality.

Thank you and all the rest for responding.
Mike Jones sounds perfect for help. But, who is Mike Jones and how can I get in touch with him. Thank you in advance

Do you have the advertised numbers on that 202/208?

Here's the cam card. The exhaust lobe is a little longer because I wanted to rev strong past 5000rpm and not just torque it up. Also, I used 1.7 rockers; the lift at the valves on the card is for 1.6 rockers.  |
