I suspect something like that was used in the original V8 powered 55/2 pickups. | | | | | Joined: Sep 2011 Posts: 50 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2011 Posts: 50 | in.teresting development , nearing compleating on 305 rebuild , when discovered a starteling discovery , no compression on any cylinders , WTF ? this is way to far along to just now discover this ! any ideas or suggestions , 55 redstove PLEASE HELP | | | | | Joined: Jul 2001 Posts: 3,887 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Jul 2001 Posts: 3,887 | ramshorn manifolds are what was original for the TF V8 and work as well as any headers ..... maybe you have a bunch of valves adjusted too tight and not closing?

Adjust the valves so you just take up the slack & leave about 2-5 thousands clearance. Go ahead & start it up when you are ready. After it warms up a bit start adjusting them down one at a time with the engine running. At first it will miss & then settle down. If so go ahead & adjust it down about a quarter turn. If they wont settle down go ahead and adjust them to 5 thousands. It will run OK that way but make a little noise. You might try again after you run it awhile. If you want to be perfect you will need to replace the cam & lifters.
If you already put in new lifters then you are adjusting them from the bottom of the travel.
