359 exhd Pete ??

That's a different story, if its going to be a toy it doesn't have to make money. Do what you want and have fun. Dads trucks were fuel slipping wonders, but his personal truck , was a beast. Mine in the day had a VTT 903 675 in it. Was so post to be an marine application ! Some body in another post is riding me because I told the fleet avg mpg. But having toys is nice!

 

Dads truck was a 3406a we went nuts on , never put it on the Dino. Learned a few tricks with the cat cooling system . Could not get it to cool, till we learned. Port the water return port head to block, port to gasket . Was almost a inch larger ? And the water pump , a plastic impeller pressed on a stainless shaft . Have different expansion rates. Would slip on the shaft . Some work , but pin them . Aftermarket radiators had not gotten popular. The V8 cummins I ran two temp gauges , over kill? But had one for each bank.
