Well, the car runs great, not surprised with the Qjet I custom built. I am running the ported vacuum source for vacuum advance, don't need a ton of timing. The rear air door was really loose for some reason, had to set it twice tighter. Boy does the posi rear work. The $50 Amazon manual trans controller with the Fastgate makes easy driving. I still need to figure out the torque converter lock up. Need to make sure the switch works. No instructions except the pictures on Amazon from that seller. Even without, 2000 rpm at 60 mph is very comfortable cruising. If Edelbrock ever releases the new heads, it will go on my nice 403 block. It looks really nice in the cylinders, had 160 psi compression. The stock crank needs turned, The local machine shop did fine with the crank grind. Hopefully will go.010" on the mains, have them and whatever on the rods, didn't spin but they down to copper. I threw bearings in it, knock went away but oil pressure was still awful. With the .040 Mr Gasket MLS head gaskets, it would be 8.87 to 1. Cometic .027" MLS would give an even 9.1 to 1 but not worth $350 for a pair shipped. The mild 218/218 roller cam would work great with this 403.
