compresion test of 125lb. Cam question
Today the engine runs fine. I had to put back the stock rockers, since advancing the cam 4* using the Mopar offset key, still put the valves in jeopardy. I bent a few hollow push rods, scared myself, changed one lifter on the worst of bent rods, twice on that valve. The cam advance on the Cloyes timing set was crazy, like 10* or more. Add to the mix, milled heads and .020 gaskets. I was stubborn and did not check valves since this a 20,000 mile old block, and heads, I had ported and replaced guides and 2.02 intakes, I feel bigger valves was a wasted effort, since it only put the valves closer to pistons. I have the new MP replacement double roller chain, it fit the Cloyes gears, a new tension-er. And it ran in August @ 106 MPH @ 13 et. also driving to and from track 100 miles away. I bought a new harmonic SFI Summit balancer, and a shinny new pulley for this season.
Just wrestled in a new head liner, so I'm ready. Auto 998, reverse Direct Connection era valve plate and casting for a manual only shift, no kick down rod needed, a local shops 2800 stall, 3.91 axle, sure grip, and 28"x 8.5" Cooper 70 R Cobras. New 750 Eddy performer is very satisfying after seat increased to .110 and float raised 1/4", secondary 4% jet increase and also choke works perfect. New heater core too. I'll post pictures tomorrow.
I'll have to build another engine before I try a different cam,, so I'll drive this until it uses oil. I have an original 80K miles, 1974, 318 forged crank block, to bore and try aluminum heads and stroker crank. By then, gasoline will be the cost problem.
The head liner looks like a puckered coffin, it's the non perforated $70 Ebay type, and not flexable. In the heat of summer I'll tighten it.
