morning Brokengate

the Mummert intake does not have this problem. i've tried to post a pic but i have a problem between the puter and the mobile/camera.

one little problem i had was i used an ARP s/s 12pt bolt kit from AlloyBoltz and the bolt heads are a little tall and the front one in the valley cover ( Mummerts ) just lifts the intake manifold. i replaced the 12pts with the hex heads supplied by John and all was fine.

Paul.  I’d say the ‘last production’ which should be the same as the current lot or batch of intakes.  The earlier production intakes have adequate clearance in this area.  Just seems that each batch of BT intake manifolds gets a little bit closer to the MSD distributors to the point that they are now contacting each other.  I’ve tried emailing Blue Thunder in regards to this but no response to the email.  In looking at the various BT intakes I have here, the newer they are, the more the aluminum excess there is in that particular area.  All other areas appear to be unaffected.  Easy enough to fix but it can be bothersome and time consuming if the intake is already bolted down before realizing there is a distributor clearance problem.

Ted: you refer to newer Blue Thunder (BT) intakes. Is that the last production or is there current production?

I use a Petronix also but I have used points in the past.

Do you trigger the MSD with points or ?? I use a Pertronix to trigger the MSD 6A in my Ranchwagon.

Mr. Ted Eaton, I took the pictures to a local machine shop and am having milling work done today.  They were invaluable in explaining what needed to be done, not sure how well that would have gone without them. Thank you Sir.

Great tech there Ted!  As for me I've had very good luck with modified stock dizzys.  I haven't seen the need for a MSD distributor, althought I do trigger an MSD box with the stock one.

The newer the Blue Thunder intake, the more the problem with the distributor clearance and especially with the MSD #8383 billet distributor.  With the newer batches of BT intakes, I’ve been simply milling the back of the intake in the milling machine.  There’s just an excess of material on the intake for some reason but easily trimmed off.  Here are some pictures showing both the before and after clearances and also with the intake clamped up in the milling machine.  A grinder can also do the same ‘removal’ operation.
