    Default BBC swap with SBC??

    just want to know what all is involved in swapping a BBC out and dropping a SBC in? can the rail kit be reused? drive line? is there a big difference in the physical size of the blocks?
    the reason for this post is that i am toying with the idea of maybe building a mild small block to drop in for playing around every weekend (pump gas) then for certain events or big lake outtings/gatherings, drop the big motor back in it. would it be more in my favor to do this or just build a mild big block so i know everything will switch right over without making drastic changes. thanks for any input.

    You would have to get a front motor plate for a small block and it would move back a couple of inches. The rear motor plate should be the same.

    if thats what you really want to do then go to the junkyard and find an old BBC out of a truck or van or whatever. going to small block is gonna require headers, motor plate etc... if you stay with a big block it should all fit

    Yea i think that would be the best thing to do, that way its just a matter of switching mota's. thanks, just wasnt sure how drastic it would be to go to a small block. well the hunt begins now for a BBC

    hahaahaha just a little.....I am just starting to chringe at me going out every single weekend and burning that 110 is going to burn the chit out of my pocket. id rather have a simple big block pump gas to go putt around the river with, then slap that power plant in there for the more serious weekend trips

    i just got a fresh 406 yesterday for a back-up for my bbc, if the bbc has any issues, i'll put it on the stand for the season , run the 406 i've got a c-cut dominator i can run with it, won't be wicked quik, but i'd bet it'd stay with 80% of the jets around here.
