Input on the 711 engine


 Share

Recommended Posts

Im looking at a 57 b61 with the 711 engine and a duplex and was wondering if i could get some of yall to throw in your two pennies about it. Is it a good engine? any common problims? anything specific to look for? Ill be honest im not real fermiliar with the older trucks (pre r model era). Its a tandem truck and im loking to convert her back into a tractor, as its got a flatbed now, and pull trailers every once in a while not often but it will get worked from time to time. And just courious if the 711 would hold up. Any input would be appreciated

I had heard about them having head gasket issues. Do you how many studs were in the corrected engines (or can you tell just by looking). Im not looking to set the world on fire going down the road cause im used to 345 & 392 IH v8's and 230 & 250 non turbo cummins so lower hp numbers im used to

Are you sure it's a 711? It would be a repower if the truck is a '57,as the 711 wasn't available until '62. I've never had a 711 that was in everyday revenue earning use,but I have one '65 B-61 with a 711 that did see occasional use moving the occasional bulldozer,hauling scrap metal,and moving other trucks,and it never gave me any problems.

They said it is a 711 but im mot sure ive not seen it in person. What engines were avail. in 56? The 711 has the 2 seperate intake manifolds? and im sorry its a 56 not sure if that makes any difference. And yes its not going to be in daily service but occasional heavy use

I had a 711 in a B model dump truck that i drove every day for 10 years, I would put bearings in it at 100.000 miles or so, and put one liner and piston in it that whole 10 years.The rest of the engine was never touched. At the end of the day I made more with that truck considering what the price of things were then. terry
