I really didn't know where else to post this. I'm having problems with installation of this LT1 intake from John Millican. The bolt holes on the four corners are drilled incorrectly? or maybe I'm missing something.

This shot shows the dilemma best:

These are ARP standard SBC stainless intake bolts and they are not torqued down to spec in these pics. They are on there pretty snug but as you can see on the 4 corners the bolts appear to have a 1/4" gap on the outer edge which I don't see closing when you torque it down. I'm worried that if we say f*ck it and torque 'em down we'll get a leak.

Do these look like incorrectly/misaligned bolt holes?

i couldn't get the link to work, could you attach the pic directly to your post (if it's not too big)? I had some bolt hole problems also, but i got them figured out.

If you can't see the pic, go here: http://groups.msn.com/BrianPspage/
and under pictures link go to the 89 IROC-Z and you'll see multiple pics.

I just want to add that it is like that on all 4 corners and all bolts are started well (they're snug) but not torqued down to spec.


Thanks,

Did you run a thread chaser or a tap in the bolt holes to remove any debris, rust or silicone that might be in the holes. Either way I would clean up the threads before I tried to torque it down.

Just a thought.

Did you contact John M. I'm sure he will be able to answer the question. When I did my conversion what ever questions I had he answered them.
