    OK I have a new frame I was gonna build up excally the way I want it and stick my body on it (but keep the 350 and 700R4 untill I have enough $$$ to build a BBC and 4L80E) the frame had a 4.3 in it origionally but I though they were the same excact frames and motor mounts am I wrong? the only reason Im ask now is someone cut part of the engine crossmember with a torch like they were trying to clearance it (they guy I bough it from was going to put a SBC in it too). BTW this is a K10 LWB

    good question im not sure but i know of a 4.3
    86 or so full size truck i can look at if needed,
    i bet at least the block mounted brackets differ from v8 ones

    probably

    but enigne mounts i dunno, call local parts store and compare them

    should be identical, although you may have to move them forward or back.

    should be identical or pretty close to it... If that frame is anything like the one on my bros jimm its gonna be a tight fight... doable but a PITA if it has a s-10 body. the firewall is your biggest problem with that combo.

    like beater k20 said you'll probably have to move the motor mounts around to get it to fit right.

    i don't think you have to change a thing to drop a SBC, should fall right in to stock frame mounts.....
    P.S. where in Fl. you at man, i live in Ocklawaha just east of Ocala.
    I drive a 18 wheeler OTR and get home every 2 weeks, maybe we can hhok up and do some wheelin...check out the website for pics of my radical 4x4

    here's an idea... measure from the rear most motor mount hole to the belhousing flange. post up the measurement, and someone here can measure a smallblock.
