new build specs

Found cracks in the saddles around the cam bearings and in the oil galley, and valley area. So, I got another block today.

This is what I am putting together this week.
1972 318 .030 over with KB silvolite pistons
-4 valve reliefs, .068 in the hole
New durabond bearings thru out.
Fel-pro .039 permatorque head gaskets
302 casting heads with 1.88/1.60 valves 62cc chambers
-gasket matched and cleaned up in the bowl
Isky tool room springs
Isky 270 Mega
-221 at .050, 270 adv., .465 lift on a 108 lsa
Speed Pro high rev lifters
Crane ductile iron rockers
Crane powermax timing set +/- 4 degrees roller
Melling HV oil pump
Edelbrock Performer for now,
-may look into a bigger dual plane or small runner single plain like holley street dominator or offy 318 port-o-sonic- small runners!
Edelbrock 600 cfm for now till I can get a double pumper and set it up right
Holley Strip Annihilator ignition with MSD coil

What do you guys think? I'm hoping for 325 real horsepower. In my duster that would be fun to drive around in. I'd love to hear what you all think.
