Red Horse Posted October 10, 2023 Share Posted October 10, 2023 Buddy just bought a mint 62 B-81SX. Non turbo. What HP would that be? Quote Link to comment https://www.bigmacktrucks.com/topic/73404-62-b-81sx/ Share on other sites More sharing options...
Freightrain Posted October 10, 2023 Share Posted October 10, 2023 Depends on intake. Single was 170? Split twin was 187? Seems that is what I remember. My 673 was a split.

doubleclutchinweasel Posted October 10, 2023 Share Posted October 10, 2023 Yep. Need the number. Could be 673. Could be 711. Was there a 707 too?

doubleclutchinweasel Posted October 10, 2023 Share Posted October 10, 2023 Could be a plate on either the engine or the fuel pump itself that lists HP. I'll try to find an example.

DC, Thx-He sent me a pix of his pump..tags are different than yours. I double checked mine which was a 237 Factory remain that guys I bought truck from had the good luck to pull from a wreck and it had only 10,000 miles. I tried checking my nos today but I'll have to pull the quarter fender off to see it. My memory says that is where my engine tag is on pump. the drive case has some numbers punched onto it but I thin k they are a part number- I'll have to put some brake cleaner on to get a good read. Unrelated question...anyone know how you determine an engine build date?

Freightrain Posted October 11, 2023 Share Posted October 11, 2023 I think a picture of the engine will help. Quote Larry 1959 B61 Liv'n Large......................

doubleclutchinweasel Posted October 11, 2023 Share Posted October 11, 2023 The numbers stamped on the case could be the engine model. The first part on mine was "T673C". That identified the engine as an ENDT-673-C, which is pretty descriptive. Not sure if the stamping "rules" were the same back then, but it might be a good place to start. I SHOULD remember where the tag was on that one, but I just can't seem to remember. There were a few tags on it (valve clearance, etc.). Also tags on the pump. For some reason, I was thinking the H.P. was listed on a tag which was attached to the engine, not the pump. But, I could be wrong. And, like Larry said, pictures might be helpful.

mowerman Posted October 11, 2023 Share Posted October 11, 2023 I had a 62F model where the non-turbo it was a 180 so I’m sure it’s somewhere in there… bob Quote Link to comment https://www.bigmacktrucks.com/topic/73404-62-b-81sx/#findComment-540039 Share on other sites More sharing options...
mowerman Posted October 11, 2023 Share Posted October 11, 2023 I’m still not sure about my 66 from what I’ve seen in literature. It’s either a 205 or 211 hp Quote Link to comment https://www.bigmacktrucks.com/topic/73404-62-b-81sx/#findComment-540040 Share on other sites More sharing options...
doubleclutchinweasel Posted October 11, 2023 Share Posted October 11, 2023 The 180s were very common, from what I remember. Quote "Eagles may soar, but weasels don't get sucked into jet engines."
