      What about the B/RB lineage?

      It was spec'd in a 58 Dodge Suburban , equipped with the first 350 'B' engine. Don't know what changed after 59 but it was also spec'd for a 59 New Yorker too.

      Another little "factoid" from years ago........I don't remember the details but at some point 289/302 Ferds went from a 'thinner' to a 'thicker' sprocket. A then friend of mine was putting together a 351W for a Bronceroid and went with a 302/289 cam---different firing order, ya know

      Anyway he had trouble it went to hell and it turned out the cam was eating it's own lobes and lifters.........because the cam drive combo was allowing the cam to walk forward/ aft

      Now I don't remember exactly, but seems to me that there were a few other engines "this is so" Also seems like it might have involved "mixing pieces" in other words not replacing chain and both sprockets.

      Don't understand. Are you saying the timing sets are the same for slant 6 and big block? They are not. The camshaft sprockets are totally different.

      Seems to me in the back of my mind PART of the slant drive fits something else, don't remember if chain or one sprocket, etc........

      EDIT found this...........

      Slant 6 / Small Block V-8 Parts Interchange - Slant Six Forum

      Small block parts that can be adapted to a slant include solid lifters, valve springs (check installed height), rod bolts, main bearing bolts (make sure they don't block oil passages). The crank snout is the same size as a small block or a big block so balancers can be adapted but may require some machining. The lower timing sprocket is the same as a big block as is the timing chain. The cam sprocket looks similar but has a different offset.

        Yeah I know. I adapted a 440 gear drive to a slant 6. I don't know if I'm actually going to use it or not, but It'll work.

            Pretty sure the BB chain is the same as the slant, ie it has the same number of links.

              Yes. It's well established the difference is the cam sprockets. I need to find my 440 cam sprocket and I'll post some pictures.

                Here you bees. All I have is a 440 double row camshaft sprocket, but they are the same offset from single to double row, so that's the same. Clearly, you can see the offset difference between the two sprockets. Also, you'll notice the 440 sprocket is larger in diameter (that could be because it's for a double roller chain). Lastly, the crank sprockets are NOT the same. They are marked differently indicating TDC for each engine, so anyone who says the timing sets are interchangeable between the slant 6 and big block is unequivocally WRONG.

                  No I'm saying the double roller chain is the same for the double roller RG-LG/B

                  I have a new Summit chain (well new never used bought back in 08) that I think is sloppy as mud...has anyone ever seen this with new kits?

                  The cogs wear also. Are you putting a new chain on old cogs? Line bore would make a stock chain looser. Run a tensioner, cheap and effective.

                  Timing chains and sprockets are matched sets. I wouldn't mix and match sprockets and chains. As previously stated they are not "Gears" 65'

                    I put a tensioner on my 273 with a Cloyes double roller. I didn't really like the way the narrow rubbing block (designed for a single chain) contacted the double roller. If I open up the front again the tensioner will get removed and another good timing set installed.

                      could run a silent or single chain with the tensioner. I ran a tensioner on a double roller and didnt see any issue, but I'm not sure what your tensioner looks like. My pad was as wide as the chain...?

                      yup. I put a double roller on my 3.9 in my 99 Dakota (same timing set as a LA/Magnum) and put a tensioner back in with it. seemed fine/

                      When I rebuilt my slant 5-6 years ago, the NEW Cloyes timing set was loose. Not just loose but waaaay loose. It looked like 200,000 mile muddy loose.
                      After obtaining part numbers for a double roller chain, cam sprocket, and crank sprocket, all separate parts from NAPA, I just bought a Rolmaster double roller set. I think it ended up being cheaper than the NAPA parts, right around 100 bucks.
