I have noticed that after I drive for 5-10 miles or more and then shut off the car, it hesitates when I go to start? Anyone experience this before and if so, what was the fix?

Alternators will only produce what is required, and as I recall most alternators actually only produce up to about 2/3's the rated amperage under normal rpm/driving anyway. So with that 55 amp factory alternator it might be producing say up to 30 amps max at any moment under extreme max current draw load. This is why the factor 10 gauge alternator to battery (secondary charging) wire is sufficient ... but one reason why I wanted to move away from the considerably smaller 14 gauge Heartbeat City sources wires reproduced for the 1969 Camaro, and get M&H to produce wires with the correct factory 10 gauge. (I guess even back then, the Cadillacs were pulling much more power than the average Camaro or Mustang).
So, with that 100 amp alternator, unless you are installing a Giga-Splat-Velocity-Blaster in the trunk that draws 50+ amps you are probably never going to draw (ie. the alternator produce) anywhere near 100 amps. If you have the mega-amp-mega-power-draw sound system (that rivals the soundstage at an AC/DC concert), then you might want to get M&H to fabricate a cable with a thicker alternator wire (8 ga, 6 ga, 4 ga, etc).
Great work Dave. It's great when GEN light goes out and it's not overcharging. I remember going through that last year.

Dave, That is great news. If your car is wired correctly, removing the battery cable while running is a quick & easy way to find out if the alternator is working. I actually just ordered a couple of rebuilt alternators through AutoZone today as I had a $45 reward to use, and like to keep a couple of them ready to go on the shelf.

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?
My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.
Many thanks,

Hey guys,
I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
