In replacing my radiator, I noticed the tank fittings were 1/2 inch instead of 5/8, looking inside, the opening was roughly 1/4 inch diameter.

I called the distributor, was told not to worry, aluminum is more efficient at cooling. So much for a 'factory fit' replacement.

The transmission is a '66 GM THD 425, and the cooling lines are definitely a higher capacity.

I thought I could laser measure the temp after a run to see if the trans is running hotter then the engine by a significant percentage.

Being ignorant of transmission design, I don't know if this obvious restriction is severe, or if the 'flow volume' of oil is not that great.

It's not that there are load issues.

The question is: should I worry? and/or add an outboard cooler, bypassing the wimpy one?

As always, thanks in advance for you help!

I don't have a tac in my truck, guess some came with it. Any recommendations for installing an after market tac.

Is there anywhere on the forum with a pdf of the 1976 users handbook, the little glovebox book?

Thanks

Would the OEM mechanical fuel pump work or would I need to het a HP Fuel Pump? I noticed the aftermarket fuel pumps do not come with a return line. Is the return line really needed? I would prefer to keep the mechanical, yet have thought about an inline electric pump. Any recommendations would be great.

I also would like to know if anyone has used a fuel shutoff valve solenoid 12VDC. I have noticed they are powered in the open position and no power in the closed position. I would like to put one in my system to enable me to shut of the fuel supply for security purposes. Any solenoid valve recommendations?

Perhaps we should have a topic for security options on our trucks.

Well, I know what is hitting it, had lots of bags of soil, mulch, that sort of thing in the bed, on way home from wmart, when hitting a drop in the road, or bump, I could hear the scrape. Why is this hitting, can I cut a space in this stupid rivited on box? And why is it rivited, and not simple bolts?
