My 71 Demon

Now that the bottom was done, time to move up to the top side of the engine. Our original plan was to reuse the OE rockers. Well we had two issues. The 340 rocker arms have left and right offset rocker arms. When I was organizing my rockers I noticed one cylinder had to left offset arms. I'm now going to try to explain this but unless your a real gear head like all of us on this web site, this will sound crazy. I looked up the price of replacing just the one rocker that was wrong from the last guy who rebuilt this engine. $8, not bad. Then I noticed that when you slide the arms down the shaft there was tons of slop. Then I noticed there was a little bit of corrosion on the shafts. Now I'm looking up all new OE rockers plus new shafts put us at about $150. Huh, that's not bad..... Then me and my dad start talking and we decided since we went with a roller cam, what about roller rockers? This is a very slippery slope. You can rationalize it several ways but this should be a model example how two gear heads quickly go from $8 to about $800 in 12 hours. Right or wrong I'm glad we decided to go this route. We only want to do this once and we wanted to do it right. Comp Cams again to the rescue.
