With that many miles on it, it's best to rebuild it before attempting to turbo it. If you don't, you'll end up with a lot of ring blowby and possible rod/main bearing failure.

You should do a full rebuild. You'd better seriously consider modifying the motor so that it'll take the much higher combustion pressures. Things to consider in a rebuild of the motor are lower compression forged pistons, like 8.50:1 CR; magneflux crank/rod assembly; shoot-peen crank/rod assembly; ARP rod bolts; steel or copper alloy head gasket with O-ringing; studs for the head instead of bolts. These suggestions are just starters.

The OEM rods will take 300 HP as long as they are good shape.
