Review on Rev up Performance: Competition Cams 2100 Magnum Double Row Timing Set for '78-'86 Chevrolet V6 and 265-400 Small Block by James Wonsley

Before you buy this, you should know that you need to clear the block for the chain. It doesn't matter, but nothing is mentioned about it. Another thing is that the chain on both sprockets on the right is too tight. The chain looks cheap, it's not really a roller chain. Seam on rolls. I ended up returning that #2100 and bought a #3100 comp camera. #3100 comes pre-stretched and real roller chain with "USA" lettering. #3100 chain slack is perfect. Chain #2100 is too tight.
