Yep. My 74 has 1.25" HD truck rotors that were re-drilled to a car pattern.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Re: Bolt pattern question

I seen some stock car (oval track section) rotors in Summit the other nite that were drilled mainly for 5x5 pattern with studs but had a 5x4 3/4 pattern also drilled if you wanted to usse that pattern....they were cheap also.

Re-drilling bolt patterns on axles,rotors,drums,hubs and more are easy for a machine shop but price will determine if you know someone there or not.

I am planning on running a Dodge Ram pattern of 5x5.5 stock to a 5x5 or 5x4 3/4 soon.I have machine shop friends though.

Re: Bolt pattern question

Any machine shop would be able to do it IF you can get them to do a small job like that. Billet aluminum adapters is another (usually cheaper) alternative. My brother has run 5 on 4-3/4 rims with adapters on his '78 GMC drag truck for about 8 years now with no problems.

Re: Bolt pattern question

I run Street stock race cars and always drilled my own. Take your time to mark out holes on a pattern and drill with a drill press.
