I need to know which 401 V8 block do I have so that I can order the correct ARP head bolts. They are either 69 and earlier or 70 and later. My has all 1/2" head bolts except for the bolts in the lower corner where the location pins are. These are 7/16" bolts.
I'm also looking at aluminum radiators. I see that I can get a universal crossflow one from Summit that will fit, but I would like to use a downflow style. There are no universal downflow style that I can find, and no one makes a direct fit for a Gremlin. It looks like a unit from a Cuda is about the right size at 26" wide and 22" high. Before a spend $300.00 I was wondering if anyone knows if this will fit. Or has anyone had better luck using a crossflow vs a downflow.
Thanks
