I have a 351W in my '88 Bronco. It seems everytime I go out and start it it starts fine when it is cool. After I have been driving it and try to restart it, it turns over really slow and sticks sometimes. Basically it sounds like when you run a battery out? I had the same issue with a 5.0 motor I had in my ranger? Is this a common problem and can it be fixed? Thanks for the help.

When mine did that, it was the starter going bad. When the starter was cool it would crank right up. When it was hot like stopping for lunch or fueling up, it sounded like the battery was almost dead. When hot, the starter was pulling 450 amps. :shocked I need to put a heat shield between the headers and the starter. I guess I will do that when I install my lift.

I have the same problem. I go through starters like a fat kid through twinkies. I do have leaky valve covers along with everything else.

I replaced my long block about a year before I had a problem with the starter. I don't think oil was the cause. Heat from the headers was my problem.

Try wrapping your starter with a heat shield.

And yes it sounds like the sarter is on it's way out.

Thanks for the help

Well I think that the heat sounds like the problem. The next question is what to build, or where to buy a heat sheild. Guess I will spend some time under the bronco figuring that out this weekend! Gotta love the Beast! Thanks for all the help!

You could also get the high torque gear drive starter that was used on later Broncos/F-Serize trucks and Mustangs. It is much stronger than the older gear drive units.

And unleas you guys are running long tube headers, heat alone shouldnt be the problem. It is a contributing facter obviously, but somthing else is helping it.

I bought my heat shield from a local performance shop. it was $ 25 for a thick sock type of wrap that attaches itself with velcro. My hot start problem was the flexplate though.
