Timing Chain Tensioner 318/360

My last post, what did the engineers do when they made the 340 back in 1967-68..did they ever use a tension thing on the timing chains, no way, Did they design the little engine so it live a long happy life at 6,000 rpm, you bet. Did any racers who built the 305 engines by de-stroking the 340 crank use a tension plate, no way again. If they didn't need it why do us? Place your finger by a running timing chain one day and think how it be long term or at high rpm's.

Just get a good timing chain and forget about it. Use the money to buy a $100+ plus chain set instead of a $50 set.
