And, with some minor improvements since discovered, maybe 440 RWHP may be in store for this stock bottom, stock cammed, stock TB motor.

Just sayin....

BINGO!!!!

Stock Nikasil is better.

Today 368 is worthless

Still waiting to hear the oil issue with closed deck,any documentation on this.

When comparing cost of a complete overhaul, with new OEM pistons, liners and rings, going the 368 route with good quality aftermarket piston/rings, rods and ductal iron liners is not significanty more expensive and has its advantages. Besides a little more displacement you can up the compression ratio to 12:1 for more power & torque and hone the liners installed the block using a modern deck plate honing methods for better piston and ring fit which helps with oil control. Aftermarket pistons also allow you to go with longer rods with the advantages a higher rod length ratio brings.

Phil,i understand the pros & cons but as we all know stock short blocks could run to 200k miles

Question still remains is the stock motor blown/broke?
If not,it's a waste to spend money for a 368, not worth the dollar to HP
Do a good top end,raise compression use Jerry's head gaskets a whole lot cheaper then doing a complete 368.
I don't think $12k-$15k is worth the extra 20hp
Basicly the pros & cons of spending this kind of money for an extra 20hp.
