70 Chevy starter/exhaust clearance - The 1947 - Present Chevrolet & GMC Truck Message Board Network

70ChevyCST · 07-20-2007, 12:05 PM

Hello all,
I'm still messing with this heat soak problem on my 1970 Chevy CST-10 (with a 1974 350, auto, stock exhaust manifolds). I tried to install the new starter that I just purchased (with the stainless steel heatshield on it pictured below) last night but the heat shield will not clear the exhaust pipe.

After giving up on the heat shield and installing just the starter...I stuck my forefinger in between the closest point between the starter and the exhaust pipe. My finger fits in there but stops at the second knuckle (~.600") Can someone out there tell me if this is normal or not? I know the starter is normally close to the exhaust but this is real close! I'm wondering if the previous owner has extra large pipes on it or something...or maybe the pipe should take an immediate bend away from the starter?...It can't go very far away though because the truck's frame is right there...I've bought a FORD starter solenoid and I 'm going to do the wiring conversion...but I'd still like to shield the starter body from all that heat...Any help whatsoever is appreciated..Thanks guys,
Bob

My 69 has the same issues, new motor, new starter, heat shield on starter and one on soleniod also. I even went as far as you and put in a Ford remote soleniod and wrap the exhaust pipe in thermal heat wrap ( for headers ). Had new exhaust ran and the guy pulled the pipe over as far away from the starter as possible, still have issues of heat soak.I'll be watching this one for any possible answers. I did notice in another thread about the correct itming for a SBC the guy said he set it to 12 BTDC and it seemed to help the starting issues, gonna checkm ine this weekend and see. Thanks for all the help !!!!!
FRUSTRATED !!!!!

If money is not an issue and you can't resolve the starter overheating, here's something to consider. Don't know much about them, but have seen them in catalogs and trucking mags.

I gave up on all of that and put on a Powermaster "High Torque" magnetic starter. That solved my problems and gave me much more space. The wires connect on the lower side and are easy to get to. No more complaints.

I agree, go with a high torque mini starter. Had all sorts of issues with the cad motor and lots of heat. Now, with the mini AND headers, that starter turns the same speed, no matter how hot or cold. Sounds different, which throws me off sometimes, but im getting used to it now. Great investment!

There are pics on the link below, look for "starter" at the top of page.
