blow proof bellhousings

[MosportGreen66]

Hi Guys,

Lets talk blow proof bellhousings. Are they one size fits all for big block and small block applications? Do I have worry about fitment issues for specific models? Looking into some vintage Ansen units.

Thanks,
Dan

May have to get off-set dowls to get alignment perfect, but pretty much one size fits all.
