Ok I have searched the web a hundred time and found nothing. I have recently dropped in a LT1 and i redrilled the heads to a regular sbc pattern and now when i go to put my distributor in it lacks about 1/4 to 3/8 of an inch. The reason I didn't buy the GMPP intake is because i plan on going to a victor jr efi later down the road. The way it is looking im going to have to buy the GMPP. Any help is greatly appreciated.
