i hate to help a guy using chevy stuff, but... here is a link to a pretty good wiring diagram for a 12v relay...

just remember,

30 = 12 hot from battery (fuse it)
86 = ground
85 = switched 12 v (trigger)
87, 87a = normally open and normally closed cant remember which is which, but this is the one which goes to the relayed device fuel pump, cooling fan ect.

Wire the pump to 87. 87A is open when the relay is triggered on 85.
A friend of mine put a proform on his 302 and it worked really nicely. I did things a little differently with my truck. I used a DuraSpark distributor, a GM HEI 4 pin module and a Ford E Core coil and it works well too. You just have to do a little wiring which is simple.

well i got my motor today. it came out of a '94-'95 mustang so it's already got the dual sump pan. he said it was bored to a 306 and had a forged rotating assembly. i have to get the heads cleaned up and i'm going to try and take the shortblock apart to rehone the cylinders because they have some surface rust from sitting out. it's not a stock cam, but i'm not sure on the specs for it. the funny thing was i ran this mustang in my camaro about a year ago before he pulled the motor. hopefully i'll be picking up a carb manifold and a holley 600 today.

Remember, The HO and the 302(SO) use two different firing orders. If you use that cam and it is an HO cam, you will have to use the HO firing order. I prefer the 351 firing order (HO).
