3.3 to 4.0 litre project help

[rag top]

from another thread:

1974 Ford XB Falcon runing a EB 4.0ltr OHC motor without EFI, Weber carby (XF), EA carby manifold with custom adaptor, EFI fuel pump, large extractors, 2.5" system with single Berkley muffler, T5 gearbox, standard XB/XC non-lsd diff, lovells front springs, extra leafs in the rear. Was a pretty simple conversion, although Im having a teething problem with the Weber. It is a bit hard to start sometimes like its flooding or something, also running the EFI pump without any regulator so it might be pumping too much fuel. Runs fine tho, big improvement over the old non-crossflow 250, and still a big improvement over the 250 cross-flow. The engine mounts look pretty standard, not sure, but looks like a straight forward swap.
