Injector Bosses

[Jim Blackwood]

Kevin, drilling and tapping holes in the runners at enough of an angle to
get anywhere near the valve head can only be done on a milling machine
AFAIK, whereas it is possible to make a jig to just cut the holes for the
weld-in bosses. I'd stay away from the epoxy unless you only care about one
season. If you don't mind spraying the injector shot on the bottom of the
runner the thread in ones should do fine.

Hello,

I was wondering what experiences people have had fitting injector bosses to
4 bbl manifolds.  I see that MSD makes a threaded boss that would seem to be
easier to install than welding/epoxying one in, but would like to know if
anyone has ever tried them before.

Thanks for the time,

Kevin Ragsdale
