I know they all F'n leak......and a jag water pump cost 1200 at auto zone. Thats enough for me to never buy one. I have had 2 318-3 forged 'truck' cranks and I have only owned 2 318's. Just get a 273 crank or even a 318 poly crank, both forged. PAW sold drilled poly cranks as 340 replacement cranks. I bought one for like $249 and ran it. It was even balanced to factory 340 parts.
