I just joined the site last night and I am having the same issues as everyone else that is looking to add a double groove crankshaft HB to a 235. I am working on the 1954 3600 pickup that I drove to high school back in the early to mid 70's and it has been in my family ever since, mostly stored out of the weather. It has the original wood in the bed and it is good enough shape that I hope to be able to run it through a planer and re-use it. Would be unique, I think, at car and truck shows to note it as the original bed wood.
I am wanting to add power steering to the old girl to make her more driver friendly, and A/C so that my former high school GF, whom I recently am re-acquainted with after 40 years and remembers being driven home from high school play practice in it, more comfortable riding to summer car shows in.
I like coilovers serpentine belt setup. Wondering what HB was used and if it could run P/S and A/C. Also, liked hotrodlincoln's post on fabricating an HB.
I stopped in the local FLAPS yesterday with my HB in hand and told them what I was in search of. They came up with a 1970 250 double groove HB that will be there Tuesday. Looked like in the picture it didn't have enough length to seat on the crank snout without hitting the timing cover first. It had no specs as far as dimensions listed so I will look at it when it comes in.
I have had the engine rebuilt at a machine shop. It is a 235, 55-57 model with the long water pump, since the original engine ran out of oil 40+ years ago. I got a bulldog cam from Tom Langdon and had it installed during the rebuild, along with dual carbs and Fenton headers. Offenhauser dual carb intake from Speedway. Got an S-10 5 speed tranny to install and S-10 rear axle on super sliders installed.
Any advice from someone who can supply pertinent info on dual groove HB's would be greatly appreciated!
