AFR 165 heads

Hey there, How many folks out there are running the AR 165's w/ 58 cc combustion chambers? I'm absolutely going to get a set of these, but am looking to find out what kind of cam to run with these. I have an AOD trans with a 2800 Precision Industries converter, 65mm Throttle Body, full exhaust, shift kit, and K&N Filter. I figure if I'm replacing the heads, I might as well do the cam and intake. I'm pretty much decided on the Cobra intake (provided I can find one). My preference is to have a strong midrange hit (around 3000 rpm) and have it keep pulling up until about 5500. Any prior experiences will be appreciated.

Thanks, Kyle

You left out one very important factor for cam selection.....gear ratio. Another thing to keep in mind is that with aftermarket heads any cam will act bigger over stock heads. With a 2800 converter and an AOD your going to want to stay small on the duration to keep from loseing all your bottom end. If you like to tinker around I'd be tempted to try the stock cam with a set of 1.7 rockers myself. Either that or look thru the ads at websites like the corral or stang net for a stock cobra cam. Just for example I have a Steeda #19 cam and its a real mutt down low even with a 3000 converter and 3.73 gears. It pulls great on top, but it really needs 4.10s with the AODE.

Steeda #19 specs are 220/226 duration 0.480 lift and 115 c/l in others not ver radical at all.

With a PI Stallion converter, bottom end is of no consequence. When you mash the gas, the engine flashes into the power band and stays there, even with a stock engine. Any cam that has a 3000-6000 power band will be a good choice with that converter.

The AFR 165s are a great choice. However, in dyno testing on a stock size engine, the AFR 185s produced more horsepower AND torque across the rpm band. I'll look up the reference when I return from vacation but it was from an extensive head test (11 heads) in either 5.0 or MM&FF about a year ago. I have the AFR 185s on my 331 and couldn't be happier with them.

A note on the AFRs: When I was setting up valve train geometry, I found that the 3/8" rocker studs provided by AFR were too short to attain proper geometry AND have sufficient thread engagement for the locks. I had to replace them with longer 7/16" ARP studs. Unfortunately I found this out AFTER buying a set of 3/8" Pro Magnum roller rockers. I had to sell those at a loss and buy a set of 7/16" rockers. Hopefully they've corrected this problem but if not, keep an eye out for it and save yourself some money and trouble.

I'll have to take you for a ride in my 95 AODE with a 2800-3000 PI converter then we will see if you change you mind. :)

I have the 165's with 58cc chambers and went with the E cam to stay legal. Good Luck

MM&FF have been running tests on heads starting with the July 2003 issue. The peak HP was 396 @ 5600 RPM and 342 ob-ft @ 4700 rpm peak torque, average hp 288.89. These heads gave a peak gain of 90hp over stock heads. The 165 with the mild setup where pretty impressive compared to the rest.

Funny thing, I have a 95GT that used to have an AODE (with shift kit) and a PI Stallion torque converter (before I converted to a 5-speed and built the

331). So a ride in you car is unnecessary.. I've driven the combination LOTS of times. Interesting that we have such different experience.
