I have been thinking of switching over to a solid roller cam. The guys here on the board have convinced me that maintenance is not that bad. My car doesn't get that many miles so maybe a once a year adjustment. Also I have finally realized that I'm just not driving it all over the place like I used to. Don't get me wrong it still will see a lot of street duty, I just realize that streetability is not a major concern. Offcourse, the way I change things it may only get one year before I start on a new combo!

My question is if getting a custom cam for my combo is worth it? The cost is not much more. The wait is usually at least a month but time isn't an issue.

The next question is about lift. My pistons are flycut to clear up to about .620. Since streetability is not a concern would it jusify the extra cost of pulling them for a deeper flycut or should I just stay to around .610 lift?

I don't want to do a complete rebuild especially since the motor is new so I will be sticking with the current compression, about 10.5-1.

My motor is a stroked standard bore 302 or 342ci. I think it can safely rev to 7K and I have heads that can support the required flow. Thanks for the advice!

Jaazzy, I have a little use roller cam you might be interested in...

If so, sent me an e-mail and I will give you all the specs.

It was too small for what I am doing and has very little time on it.

The duration also plays a big role in the valve to piston clearance. If you stay with the same duration, you will be fine, but if you increase the duration, even with what should seem like a safe amount of clearance, you might run into problems.

Just something else to think about.

I understand this. My duration is now 238/248 at .050.

The Fastback has a 342" with a solid roller (Chet Herbert) and AFR 185s. I would be interested in what distributor gear you end up running. I was told that solid rollers require a bronze gear even though hydraulic rollers can use the steel or bronze. My concern is the durability of the bronze gear in a car that sees 99% of its driving on the street. I'm approaching 500 miles on the engine, so I'll check the gear in the near future.

The Extreme Energy line of mechanical rollers from CompCams do not require the bronze gear.
