Lower Rad Hose

[jons70]

Just finishing up the final touches on my 454/Tremec swap in my 67 C10. I ordered a lower hose for a 68 BB C10 and its no where near close to fitting. The 454 I put in has a long nose water pump and I can only assume the 68 BB has a short nose water pump, hence why the hose might not fit. For now I fabricated my own out of multiple hose with steel inserts and gear clamps to get the shape I need and to get the thing going. I don't really want to go with one of those tacky universal hoses. I'm sure there's someone on here that's put a BB in one of these trucks with the long nose pump. Just like everything else with this swap...... Fabrication, Fabrication, Modification......
Any help would be much appreciated.

Thanks
Jon

1973 was the first year for a 454 pickup. Full size cars had big blocks also.

What size is the outlet on the radiator. Does it come straight out of the radiator or have a slight bend in it??? My 68 BB has a slight bend in the lower radiator outlet, never seen on on any other application...

I used a dayco number 70324 for a 73 Camaro w/ a much larger radiator than was ever installed in any 2nd gen Camaro. It had the larger lower outlet on the radiator. This was a small block application, but non stock stuff...

I ran into the same problem that your having and I finally gave in to the universal flex hose. I shopped around for a while and couldn't find anything that would fit. If you find something I would like to know about it so I can get rid of the flex hose.

Problem solved. I found out that the lower hose that was provided to me was for a 6cyl. I bought a lower rad hose for a 1971 C10 with a 402. A little trimming on the radiator end and it fits perfectly.
The rad is a performance replacement aluminum that looks just like the factory copper one with the exception of the welded tanks and water outlets. Nice shot of semi-gloss black and you can't tell unless you look really carefully. The lower water outlet kicks up just like the factory BB rad does
