I have a '90 sbc 350 that I need to mount a pre '86 intake.
I understand the two center bolts went from 90 to 72 degrees around '86 and up.
Someone said I can drill or enlongate the two holes to change the bolt angle. Is this possible?

Its going into an old '66 2 ton flatbed I just use around the ranch. The bolt angle is holding me up on this project.
Anyone here know? I found nothing on the web.
