428 starter drags when hot

[Dominik]

Hello Tom!

The strange thing is that your new units work for a bit, then fail.

Let me ask the obvious:
How are your connectors and cables? Did you try a second source of power in parallel (jumper cables from your other car)?

Did you do the voltage drop test?

What happes if you take the new starter out and fit it back in?

Is the ground cable from battery to frame large enough? Do you have a large ground from frame to motor?

paint cleaned off frame before ground is attached?

Dom et al,

I have received several suggestions on the 460 and Big Block Ford web sites that I'm going to try - well, at least two of them.

1) Add a separate solenoid away from the headers on the firewall. Here are a couple of links to give the wiring: Adding a Remote Starter Solenoid to your Chevy, My Way

(Ignore the mention of the Ch3^, it uses the Ford part) and Starter goes click-click when hot - 460 Ford Forum

Still not sure why the solenoid helps, but several knowledgeable folks have endorsed that approach.

2.) I think I'll try a heat shield along with it for good measure.

A friend once said about my approach to a problem was "when you see a problem, you just start throwin' hammers" LOL

Hello - had the same problem with my HiPo FE and did all the tricks shielding etc with little success. Old timer at the truck wrecking yard said "Use a bloody big battery".

Fitted said Bloody Big Battery - never had a problem since - many years now.
