I am trying to choose between two different solenoid heat shields and need comments/answers.
1) I have a shield that is a closed cylinder except for about 1/5 open. There are two tabs w/holes for attaching to the screws on the end of the solenoid. My concern is how well that this will clear the 2 wires on top of the solenoid and the retainer for the wires?
2) "Year one" sells a type, for small blocks, that has one mounting tab on each end. One is slotted and the other has a closed hole.Can somebody clarify how this type attaches? Also, how well does this type clear the wires and wire retainer?

Which of the above types is the better?

57Starchief, I'm no electrical genius, but will hit the hilites on what problems I had. Slow cranking when hot as in shut down for just a few minutes while in the 7-11 for a six pack. Cleaned all connections from the battery to starter and a 2 guage ground cable from the battery to the block. Grounds I believe are the key to many electrical problems. No need to use a heat shield unless you have no clearance between exhaust and solenoid, except on very high compression engines.

Greg is right. Heat soak is over-rated even with big headers. A poor ground can cause big problems. Make sure the chassi, frame , and engine are all connected with good ground straps.

Thanks for the suggestions.
My ground cable is original except with a "clamp on" terminal at the battery and a Ground Disconnector Switch, which is also "clamped on". I am going to replace those with an ACDelco ground cable, 4 gauge.

I had a "sit and have a 12-pack" or call AAA for a jump problem with my '71. I thought it was a heat-soak problem. I put a Moroso aluminum heat shield..didn't help. Ok. Went and bought a AC Delco starter..didn't help. Damn
. Got a 1000ca/850cca Delco battery. Nope, still wouldn't start after getting hot. Since I already had ground straps there was only one link left...cables. The Delco wholesaler I bought all these Delco parts from custom fabbed some battery cables out of 1/0 guage wire (this is some BIG cable). Hooked me up for $12 and I haven't had a problem since. It was my battery cables the whole time. One or both were corroded and being only 8 guage didn't help. Get some 1/0 guage wire and you'll be golden for years to come
