Timing chain recommendation

my point exactly too many variables for a non engineer
so buy a set with one of the names mentioned or get a melling, cloyes etc
for example cloyes makes a gear set for the racing Iron duke pontiac with a iron or steel cam gear instead of aluminum or fiber- which get destroyed with the shaking 4 banger
This gear set also works on a chevy 194-292 chevy 6- which I run
good engineers solving a real problem
remember all chain designs do not interchange with all gears- they gotta match if you are just getting a new chain
what does everyone think of the tensioners/ idlers for the SBM?
Which is WHY I said "Rolon" brand for his Enginetechs set: as I Know both mate up & Still Economic to buy with quality..I think you are starting to loose the buyers (& my) point if you start saying buy Cloyes etc when wanting to upgrade from the 'link-belt' type Std sets to a low cost set of Sprockets...there can be quite a chunk of $ difference, remember he said only cost $21 odd.
Yes re fibre gears: that problem has been around since Flathead ford days, as shown as a cure for the lower box in my pic above for 1 ...
