Default Comp and Jesel belt drive.

I have been looking through some of my magazines and doing some searching online, I see that CompCams makes a couple of different belt drives and Jesel has two different ones as well. I have been leaning toward the Jesel drives, but now they offer a 1 piece upper pulley system that is around $250 less than the two piece system. What would be the benefit of the two piece vs. the one piece?? Is the two piece worth the extra $$? Has anyone used the CompCams belt drives and how do you like them? Thanks.

I've got a comp-cam on a sm/blk 434" but have not installed the engine in the car yet. I also have a used jessel under the work bench, that i bough after the purchase of the comp-cam unit. I've run jessel in the past (2 pc.) and i can tell you there is no comparsion on workmanship between the jessel and the comp-cam unit, plus when i started unwrapping the comp-cam unit, i found a made in China sticker on some of the assembly parts. The one i bought does not have the idler pulley, i wouldn't buy another one but since i already it installed, i'm going to try it :?: hoping it don't bite me in the butt.

Zip.

We are at present using the 2 pc BBChev Jesel piece & really like it Quality fitment,tops.I wouldn't by choice use a belt system with an idler either.Having not seen a one peice top gear I can't say for sure but I would wonder how fast timing changes would be accomplished,something that is very quick & east with the 2 pc system.

I am running the Comp on my BBC and I like it. I have not had any problems out of it.

I wouldn't look at either one, CV products makes billet belt drives that cost less then Jesel, and much nicer and easier to install then both.

CV Products make the best timing belt by far. Used the jesel and had nothing but leaks and clearance problems on my 10.2 dart big block. I highly recommend CV Products. Very nice looking billet cover also.

I was told that the block requires machining to fit the jesel back plate. Is this true or is it a bolt on replacement to a chain?
