Stockish 340 upgrades, cam needed

Okay, sorry, I meant the .506 I/E 267 Adv. [email protected] on a 108. But the whiplash you mentioned with .550/223 looks pretty good, to. If the heads are 65 cc's the Edelbrock .050 gasket would give 9.8:1 with .035 (right up to the limit) quench/piston to head clearance.
