| RE: Roller Cam |

A hydraulic roller should be fine, but if you want to go solid, there's a concern that the roller will scuff the cam. I don't know if it'll actually happen, but that's what I've heard. A rev-kit should fix this, but I don't even know if it's a problem. Oh yeah, the concern is for street-driven cars, not strip.
I tested some roller cams in dyno2000 and they seemed to pull about the same as my normal solid cam until about 4,500 rpm's. The roller past the solid at 4,500 and kept going up where it made about 50hp more than my normal solid. If I had my engine apart, I'd set it up with that cam. Dyno2000 has a feature where you can test all specs within a range. You plug in your flow-bench numbers, and it does the cam searching for you. The cam it chose is actually very close to the CompCams 288-R10. The 308 and 328 had higher numbers.
Porting the heads seemed to help about 15-20hp. So did a single plane versus a dual plane. Yeah, the dual plane had more torque earlier, but the numbers were so big, it wasn't like the engine was hurting for torque.
So, if I could do it all over, I'd port my heads, run a single plane tunnel wedge 2x4, and I'd run a custom roller - chosen after putting my heads on a flow bench. |
