I recently bought a 1965 FI roadster. It has a close ratio 4sp and 4.11 gears. It is 90% original but has things like modern spark cables, spin on oil filter etc. The car runs fairly well but not perfectly. The "issues" are:
Even with 38 deg of timing the engine is not pinging on pump gas (elevation 2100'). Do I have 11:1 compression?
The idle is somewhat erratic. It will idle OK then it wants to die. Could be ignition or FI. At high rpm (no load) the timing starts jumping around. The local guru attributes this to slop in the timing chain but I am not sure about this.
Acceleration is OK but not startling. My only other experience was a 69 with a built 468 engine and a Ford GT that I currently have. Both obviously have a lot more power. I expected that the fuelie would be capable of spinning the tires from a rolling start on a good surface. I have Dunlap 215/70 radial tires.
So far I have:
Removed the distributor. The bushings seem solid and I can get a .016" gauge under one side so I would guess that end play is about .010"
If I put my hand on the distributor cap with the engine running I get shocked but I do not see sparks in the dark and the engine is not obviously missing when driven. I will replace the boots.
I pulled one plug and it looked good.
I am wondering it my balancer could have slipped(???) and now the timing mark is off.
Any suggestions, observations or comments are appreciated.
