1970 Swinger 340 resto
Not much to update but some slow progress. Got the valve job with a 70 degree throat cut and one head blended into the bowl. Gasket matched with radius of the pushrod pinch to the straight port wall. Still more work to do around the guide bosses and clean up the chambers a bit more. Guide cutter and seals to be delivered tomorrow to make room for the lift of my cam with 1.6 ratio. Of .506. Chamber finishing may get me to about 62cc and 10.25CR. Then I can finally put it all together.
