340 Tune Up
I wish I had started to take pictures sooner of this 340 project that I'm working on.
MoparLvr here on the board has a Really Really nice 69 Swinger that I'm going to tune on throughout the summer.
First step is to port his X heads and intake to see how much I can pick it up perf wise.Along with the porting he has a nice little Holley 750 Ultra carb to top things off.
I've got the heads to what I'd call 85% finished...I'll give them a nice 5 angle valve job and give the valves a back cut.
Then I'll give them a trip to the flow bench to see what we have.After that I'll touch up the port work and make the as pretty as I can "clean up around the guide boss and double check the short sides"
Then we'll put it back together and see how sharp we can get the tune up in it.
I'll also let Bill try a couple of different Ign boxes to see if he can feel the improvement as the tune up progresses with each box.
