Wouldn't mind having the v6 in my collection. I wonder what happened to the 6 of them?

CALVIN-THE V8 WASNT A BAD ENGINE,THEY WANTED TO MUCH OUT OF IT.THE HARVEY ENGINEER HAS ALL THE TEST DATA ON THE HD41 TEST WITH THE V8.WE WILL FIND OUT MORE!!!

you never want to pull the max rated hp out of a engine,the rated 600hp was intermintent rating.you need some cushion.just like the hd21&945 loader the engines were 300hp and 315hp in the 945 (25000).the v12 cummins (1710ci)could make alot more than 525hp,but you need some longevity.they could of used the v8 in the hd31(425hp)that came out in 76? Mr Zagotta an engineer that worked on the v series told me they should of never played with the v8 version,they were a 60 degree block and that it was hard to balance.they had to use two counter balancers spinning twice the rpm of the crankshaft.the balancers failed prematurely.at the end they re engineered the balancers,but corporate thought the v12 was a better product.

This is extremely interesting big al! Thanks for sharing.
