I am doing a refresh on my 1776 EFI turbo motor with FK7 cam and dual spring AA500 heads(was previously running w100 cam and stock heads with HD single springs) my factory cam and crank gears both showed significant wear and quite a bit of slop. I am wanting to run good quality straight cuts that aren't too loud. What do you recommend? I am looking at CB, Engle and Scat. Any experience with these and what do you like or not?
Thanks

Im running the CB Performance adjustable gears. The fit and finish is perfect and are as quiet as stock (which kind of bummed me out, I wanted them to be noisey). They only thing on my engine that isn't from CB is the case itself (AE AS41), their stuff is the best!

I have used the new CB pro gears in two engines after loosing trust in CB straight cut gears after one split in half during a break in years ago. The new ones seem to be good and they have the spacer built right onto the crank gear.

Well, I now have a set of Engle straight cuts, and both types of the CB straight cut gears. The machining on the CB gears is very rough, the Engles look very nice. I am considering having them all REM polished(should make them more quite and less wear) I have a somewhat local place that does REM polishing and was quoted $20 for each set. The gentleman I talked with at Performance Metals(REM polishing) said he recently polished gears for a SBC gear drive setup and was disappointed because there was no whine
. I ended up using German helical gears on my 1776, after receiving the CB pro comp gears and how ugly the machine work was I couldn't install them, hoping that polishing them will make them usable.

Giving this thread a little bump!
Does anyone have any experience with the straight cut cam gears from Berg?

I hope this helps. It has detail and it also covers most of the basic reason's as to "why".

This argument/discussion has been going on for a long time and I suspect it will continue on also.

I am using the CB pro series straight cut gears (part # 1400) in 2 motors. I had them REM polished and they work well and are quiet.
Not sure about the Berg straight cuts, couldn't find them on their website, I wonder if they have them built or just resell China parts(like their ratio rockers).
Good Luck

I installed CB's 1399 straight cut cam gears in my last motor (2276) with fk10 cam and CB's 650 spring on the wedgeport heads and the gears are actually pretty quiet. I have been using this motor on the street for about the last year and half and the gears have worked very well for me. Didn't do anything special to the gears other than the normal installation, check cam timing, back lash. I will most likely get another set for my next motor.
