Points condensers are usually 0.25 micro farad, not higher. Using a larger [ mfd ] capacitor will result in an erosion hole being formed in the breaker arm point.....& a corresponding build up of metal on the fixed point. Timing will also change because the actual contact point has changed.
Bridge the bat cable terminal on the starter with the small cable, using a screwdriver tip. If it cranks, it is the relay or wiring. No crank, it is the starter. I presume the battery cables/lugs have been checked for looseness/corrosion.
You can get some really 'odd' cooling problems. When I put a 440 in my 1970 Dart, I could not get the correct top rad hose for it. Never an option here. So I used a 'universal' corrugated hose. Cooled ok just cruising, If rpm went to 6000, temp would increase until coolant boiled. To avoid...
The reason Multi spark was used at low rpms with CD ign is because the CD spark is about 1/10th the duration of an inductive ign spark. At low rpms, a long duration [ relatively ] spark is needed & a single CD spark could cause misfire. Hence, multi spark. Nothing to do with 'cross fire to the...
The shims will wear the alum pedestal, post #8? Don't think so.....
The original 1958/9 factory heads came with alum blocks pushed onto the shaft & acted as the hold-downs. No shims used, rockers in contact with the alum..& no wear. Not sure what year the alum blocks stopped.
When you rev the engine after setting timing....does the engine come back to the same idle rpm?
If yes: sounds like the centri weights in the dist are sticking
If no: higher rpm, sounds like weights could be advancing with the rpm.
Disconnect & plug the PCV port. Try again, report back.
..And HEI modules are super cheap. If you are worried about failure, you can piggy back a spare module one onto the operative module.
5 min to swap 4 wires if needed...
A no brainer....
Turbine,
Nope, you do not want to trade current for voltage. It is the heat in the spark that ignites the mixture, & the heat comes from the current...
RJ,
I haven't changed my opinion at all. Read what I said: if retaining the factory coil, bal res MUST be kept. HEI is internally current regulated to 5.5 amps; some electronic device, not a bal res, is INSIDE the module limiting current. You get the BEST from the module by using a low res coil...
...the GTO dist to take the Chrys reluctor. Original GTO coil was retained. 5 pin Chrys ECU was used with dual bal res. Ign timing was set at factory 6* BTDC, as it had been with the points.
Idle was noticeably smoother & had slightly increased rpm. Smoother means less misfires, more hp. higher...
I would not worry about it. You have the thrust washer there to take up clearance. What I would be concerned with is that the roller tip is centered on the valve, & that may require r/shaft shims.
Best bang for the buck is electronic, using the HEI 4 pin module. Module can be mounted via heat sink onto the dist body. Neat & compact. You can use your original coil but you will have to keep the bal res, which becomes a failure point. If you use an E core coil like the MSD #8207, you can...
Rad cap for a recovery system is different to the standard cap. Make sure you have the correct cap.
If the rad is old, it may be blocked with sludge. Flushing it out does NOT guarantee that all the sludge will be removed. The PROPER way is to take the rad to a rad shop. They will remove the...
Edel 800 AVS2 carb. Do not go too big with a 3.23 rear end. You have the Torker intake, which means all 4 carb bbls are accessed by each cyl. If you had a dual plane intake such as Performer or RPM, only half the carb is accessed by each cyl.
