    SBC in 1st gen?

    I got a '65 recently that has an old I6 engine but no xmsn. thinking of going with a SBC 350 and 700r4. will it fit? I've been told the 1st gen doghouse is too small.

    Oh yes...

    With the correct fabrication there are vans with blown big block rats in them.

    The problem is cross members and the fact the 1st gen doghouse only fits the narrow inline 4 or 6 cylinder.
    You can make your own or use one parted from a 2nd gen.
    That is wider to accommodate the V8 option for those years.

    As a personal choice, I would make it removable for easier periodic maintenance.
    Once you see how tight a V8 is when stuffed in there....

    Anyone have crossmember/trans support info?

      I put a 350 in my 66. The only thing I had to do is I put 2ng gen doghouse sides on it. The cross member and motor mounts are from the 6 cyl.

                I have a 350 in my 65 and my 66...it has more than enough engine and I went the 200r4 trans. 2nd gen dog house for sure and drop the crossmember 2" with a spacer to help with cooling and driveshaft angles. My choice would have been a 327 if I could find one......but like the newer 6 cylinder options...why do what everybody else is doing???.... mine may be converted to electric at some point.... who noes....think outside the mainstream choice and fo something that wows everyone!

                  SBC and BBC will bolt right onto the stock rubber mounts and you will have to fab a trans crossmember.....Sides of the box and corresponding floor will have to be cut away and "side bubbles" made.....Try to fab something that can be removed for changing spark plugs....It's popular to swap a 67-70 box in and that also affords the benefit of the wider and lower cross-flow radiator, but you still end up constrained by limited access through the narrow lid opening....
                  For throttle, a 33c marine cable is ideal because it can be pushed......Bolt the gates together on your stock 3spd shifter and set up a 43c marine cable to shift the automatic.....
