    I'm to the point of buying an intake for my 235. The choice is between an Offy 3x1 or an Offy 2x1.

    The engine is a 1955 235 bored .060, with an Isky E2 cam, and a 1961 848 head that has been ported & polished. The dist. is a Mallory Unilite and it has Clifford tube headers.

    My question is about carb/intake/air cleaner clearance. The engine is going in a 1955 2nd series pickup with stock motor mounts and a stick shift trans.

    Does anyone definitely know if the Offy 3x1 intake with Roch, 1 bc carbs will clear the firewall and hood? I have searched many books, catalogs and threads here on The HAMB. Some say that it will clear, some say it will not. Does anyone know about this specific application?

    Thanks for all replys.

    Well, the rear carb is directly inline with the rear port, so if you have the engine in the truck, take a carb and place it in that position and see what you have for space.

    I had to cut the firewall in my '53 truck for tripower.

    OK, since there are no takers on general info I do have a specific question.
    I've seen several references (different websites) to a 261 build that used GMC rods and Buick pistons. With only a mention of the build, there were no supporting facts or numbers.
    Has anyone here used the combo and what are the benefits of doing so?
    I've just torn down a 261 that I had planned on doing a fairly stock build on but was given a set of GMC rods that could possibly be used if worth the trouble. Any experienced advise would be appreciated.

    Any other tips appreciated as well.

    Try the Inliners site. Thinking Tom Langdan was the creator of this combination, there may be something on his website. dyno dave

    I called and spoke to Tom on this after that post since there is only mention of the possibility on any site you go to. (Even inliners)
    I don't have all of the measurements and part numbers in front of me at the moment but you have to use GM rods from a 302. They are the only ones that will work with this combo. They will need to be narrowed a bit. Also, the rods are designed for floating pin but the Buick pistons are press fit so you have to shim the rods before pressing the Pistons.
    I have all the particulars if anyone else is thinking of doing this. My poisons and rods are done, I just have to get everything together and balanced. Hoping to have it all back together before next spring.

    I'll keep the thread alive - anybody have a line on good machine shops in the southeast that have the knowledge and "tricks" to handle a 235 with confidence? Wonder how many would look crazy at me if I walked in and asked about a torque plate for my 235 build?

    If you haven't asked about Stovebolt rebuilders on the Chevy Talk or Stovebolt websites, you might want to.

    Call Tom Langdon at Stovebolt or go to http://www.langdonsstovebolt.com/ he has a lot of good info on his site. I’m pleased with the “BullDog” cam i got from him in my 261.

    Thinking of doing a build that is similar to the May 1955 Chevy 261 Build. I have most of the parts now.
    McGurk # 18 Camshaft
    Grant Rings
    McGurk Pushrods
    Jahns 3 7/8 Pistons
    McGurk Triple Intake

    Anyone have any thoughts. I have a 261 that is going in my 47 Chevy business coupe, but if I build another I was thinking of duplicating the 1955 Build.
