And I wonder why i hard time setting the timing...
well..left the old distributor in..put the plugs, wires and cap back on..fired engine this afternoon for a few minutes...looks like I only got 25 degree of total time...will double check tomorrow....went i can run it a little longer....while no one is home...
this engine (suppose to be spare) came out of our 71 dart and was run in the 71 demon at MATS 2011, I never checked the balancer since the engine was assemble a few years ago, so somewhere it start to slip...I changed distributors at MATS 2011 due to a bad pick up coil, so I would guess that since then the timing has been off......I remember last summer at Top Gun Raceway, I checked the valves one morning there and checked the timing and now i remember the timing looked funny and I had a hard time see the marks...i just commented to myself dont every buy another chrome balancer cause it was a pain to see the timing marks..
anyway...I think I found out why the car is down a couple mph...and now i have new valve springs too...LOL
