Early 273s and aftermarket intakes

[Tony Brummett <brummett@xxxxxxxxx>]

My brother is rebuilding a 1964 273 and wants to put a more recent
aluminum 4bbl intake on it.  I know the head-intake bolt angle for '64
and '65 is different than '66 and up LA engines, and I've heard that
you can drill out the holes in the intake to make up for it, but I
can't find any real info about it.  Does anyone know more?

Is this something you can do without a drill press?  Do you have to
make the angle more vertical or shallower?  You should use larger
washers on the bolts, right?

Thanks,
