".....when people see that i blew their 454 out of the water with a 305....."

"....... Just build a good, stout short block......"

Tech hit it right on the head. Not trying to burst your bubble but now's time for a reality check. How deep are your pockets? Depending on your boost levels your looking at things like: steel crank, the good rods you mentioned, line boring, 4 bolt main caps, premium forged blower pistons (for a less than popular motor), final honing with a deck plate, O Ringing the block, HD oiling system, premium rod bolts/main studs, and a bunch of other little items I'm overlooking, and thats just the bottom end. The alternative is to keep putting engines under the blowers.
