4" Oxy for the street ? Anyone done it ?

Post by Unkl Ian »

I've read lots of speculation,both ways.

Has anyone actually done a 4" bore Oxyboxer for the street ?
Will it live ?


How about 96 or 97mm Type 4 cylinders ?
(yes,nothing lines up):wink:

96 x 82 = 2374
97 x 82 = 2424

It's 2 or 3 threads down from this one.

The case and cylinders are absolutely no issue whatsoever. The problem is the cylinder heads. Aside from the JPM heads, few streetable heads exist that will accept the modifications/stud relocation necessary to run larger than 94mm bores.
