I am replacing the timing gears on my GS and was wondering if there was a specific brand that is better? I think my local shop carries 'Cloyes'. Any recomendations would be great. Thanks,
many race shops use only one timing set and that would be rollmaster crane sells it renamed crane billet timing chain set . It has nine keyways for maximum adjustability and can be had in various undersizes if you have had your engine lined bored and i have no vested interest if rollmaster:beer :beer :bglasses:
I recently rebuilt my 70 455 using a TA adjustable billet set and degreed my TA 113 cam at 6 degrees advanced and found it to be very accurate. The specs were dead on and the engine fired up immediately on the test stand and ran well. Kurt
Thanks for the input guys. Is it worth it if I do not plan on altering the advance? I was kinda just lookin' for stock replacement with a good quality set.
is it worth the money i would say yes I am going to replace the chain on my stock 78 350 and going with rollmaster do you need to spend that much probably not but people will spend 250 bucks for a set a valve covers and look for cheap rotating parts go figureo No: o No: o No:
I used the stock Cloyes set and it worked out really well. I pulled the stock set at 146k miles. The stock Cloyes is certainly better than the original. Do the math. But this two cents is from a basically bone stock engine. The steel cam gear is definitely an upgrade from the original nylon. The chain is probably equivalent to original. The Cloyes stock set is probably fine for stock replacement. If you want more control over timing and minimal chain stretch over the life of the engine - definitely go with the better set. I'm not realistically expecting to get another 100k before I rebuild the engine. When I do, I won't use the stock set; even if it was going to be a bone stock rebuild - which it won't be.
Yeah, I figured I would switch them out even thought the car only has 29K miles on it and the nylon appears to be okay (couldn't see any stress fractures), but I am not going to risk it. the chain does seem to have a lot of play in it. I am planning on keeping it bone stock, but I also plan on running it down the track. Thanks for the input. Might be worth going with the better set now?!?!
I've heard from a buick engine builder that the rollmaster doesn't stretch, over time, hardly at all; and that even less quality double roller chains do. Steve Walsh
