Currently doing a street engine rebuild for my 1963 dodge d100 and wondering if its worth getting a true roller timing set or going with a standard replacement like cloyes.

0.060 overbore
block decked .070
head with get around 0.030
Oregon #2106r cam
head will get new valves and bowls cleaned up

manual transmission with 3.55 gear ratio

Thanks!

You will be fine with a standard set. Just be sure and check the "slop" in the new chain. I had 2 new ones that were pretty loose out of the box!

Also make sure to degree in the cam. Don't just go "dot to dot".

Yeah I was going to get a degree wheel and do it correctly.

Given the high prevalence of crummy (or worse-than-crummy) new parts these days, I'd say the best timing chain and sprocket set is the best-quality one you can get, regardless of which style it is. It's been long enough since I bought one that I don't know if the Rollmaster parts are still primo, or if they've fallen, too.

Too many people who were born on third base actually believe they've hit a triple.

Rollmaster is still good in my opinion. They use Iwiss double roller chains and seemingly good sprockets. Often their lower sprocket is too tight on the crank and can benefit from a light amount of material removal with a 120 grit sanding roll on a dremel or die grinder.

I do not mess with standard catalog stuff for timing chains. I am sure there are good parts out there, but quality can be hit or miss as Rick noted.

When I built my last/6 I lucked into an MP double roller chain and gear set about halfway thru the build.
I also got the last cloyes double roller setup that rock auto had at the time for it. I had to get the chain and each gear separately from rock auto at the time.
I had the cloyes setup on there and it seemed fine (it was definitely "old stock") compared to recent cloyes crap parts I've bought for other jobs (not /6) and ultimately returned because of having as much slop as what I was trying to replace.
I noticed the " iwiss" name on the MP setup and I don't remember why I did this but I wound up using the MP setup with its "Iwiss" branded chain. I still have that cloyes double roller setup around here somewhere.
I didn't notice any problems with that set of cloyes parts and they would have been more than fine on there. But I remember seeing talk about the "Iwiss" chain on the various forums and that there was something "special" about them. I don't remember what the significance of this was at the time but I figured if everyone was talking about it there must be something to it.
The weird part was that I didn't go looking for this particular MP chain and gears setup // i got it among a pile of other parts I bought, and that wasn't the part of the parts lot I was buying it for ... But I had it so I used it.

Agreed! One other thing is that you need to check the line up on the gears too. The lower gear on mine needed @ .040 or .060 trimmed off the back to get a good line up with the top gear

My guess is that the offset is due to the block and crank you are using, and not the timing set. It's worth checking when you put everything together for sure. I had one that was quite a bit off and I removed a bit from the crank gear, IIRC.

Also, all the non-Rollmaster timing chains these days use a slot for the cam dowel that makes degreeing in with an offset dowel a pain.

I used a JP billet set and ended up having to take some material off the back of the crank sprocket for proper alignment
