AAAAHHH!! Frustrated and need help! - 06/09/11 05:54 PM

I'm so close to the finish line with this restore but just can't seem to cross the dam thing.

Car Info:
72 Cuda
1969 340 w/complete MSD ign, Comp 280H cam, & 650 4150
4 speed

3 problems:

1. Wiring: When I wired in the MSD 6AL I wired the initial power wire into the acc that would normally goto an electric choke. I also wired the electric fuel pump in on the same acc wire. The car will not start by the key but will by a starter button hooked to the batt and starter silinoid. Where should I wire the MSD and fuel pump to so that when the key is turned on it all gets the power they need?

2. The motor is a 1969 340 and has the timing marks cast into the cover on the passenger side behind the watter pump inlet, so you cant see them. To add to the problem the balancer is an aftermarket piece and so the timing marks are 90deg off. I cannot seem to get this timing right. Comp said that the initial timing is 12-14 deg total timing is 36-38 and they want it all in before 3000. So according to MSD they said to use the silver bushing (25 Deg) and by their timing graph (E) I should use one light silver spring and one light blue spring and this is what I have done. Since I cannot use the timing light and do it the correct way im trying to get it close by ear. I can get it sounding right in the shop but when I test drive it the timing sounds way off when the motor is under a load. What should I do???

3. Last of all the brakes... The car came with front disks (which have been rebuilt) the rear have been converted using SSBC's conversion kit. I can get everything to bleed out properly but while on the test drive the brakes are barely grabbing. I have gone over every connection and bled them again and all looks good but still almost NO stopping power. What the heck??

Any Ideas??

On my dart when I had the 6AL I took that small red wire and attached it to the brown wire in the harness behind the distributor..this wire is the on that feeds the positive side of the distributor..Power when key on...

my msd gets juice from the coil and fuel pump i went straight to the fuse block with a shut-off in between. for timing you have to be careful. some dial-back lights work ok with msd and some don't. mine is a Sears model and works fine. and don't use solid core plug wires period. can't help with the brakes, sorry

Replace the timing cover with the CORRECT later model part . or get the engine to TDC and create timing marks where they can be seen if you don't want to do what you should have done initially .

msd is supposed to be hook direct to batt on both pos and neg , the kon/off can be wired to a keyed fuse box terminal
by no means would it be wired to the coil

or get the correct wp/damper/rad to go with the t-cover you have.

use a vac gauge on the full vac port of the carb,advance timeing till you get your highest vac reading,adjust idle air screws to get highest vac reading playing with it till you get the highest vac reading

then back it off one full # and lock the dist down (example..if highest is 19..back it down to 18)

this will get you real close and in the ball park for timeing with out a time light

then get a light on it and make note of where its at for future referance.

you can now use that as a base line,then test drive and adjust more if needed with a light and the vac gauge together to fine turn timeing and the carb setting.

I think you missed a wire.
acc on gets cut when you go to start.
you probably should pull power from the line before the balast, or the starter solioid.

Your brake issue might be the same thing that my friend did on his Dart. He had the calipers switched from left to right. If the bleeder screw is not at the highest point,pointing up,they will not bleed properly. He had the bleeders pointing down. After switching the calipers from left to right,they bleed out fine,problem solved. Maybe you solution will be the same.
