Need tuning help on 340 (Part II)

the biiger bushing slows the timing curve down are yourunning a msd or mopar hei,petronics sounds like an msd sounds like your good for your trip run fat /rich
when you get home take that big spring back off put in the medium silver spring
the lighter bushing brings it in quicker, the heavy slower crackedback has the perfect bushing for you that the msd package does not include in the spring and correct weight bushing , just went thru all this with my 360 heavy spring heavy weight , I couldn't spin my tires If i was tied to a stump . find that perfect meduim its gr8 for the hyway if you have a low stall mineis a 3200yoursoundlike a stockorjust above like 2400. So rob said get that big spring off put on the medium silver and play the graf will show you the curve = spring and weight torpm pick up
look it up under MSD .the pack is missing 2 in between weights / bushings , wick robhas those 2 bushings /weights , I believe they are 13,14 gram . I put391 gears in so I need to be all in at 3200 to launch ,theni canleave 150 fett ofrubber in the rearview mirror , so for racing a touch to much ans at 25 mph in town I would be under my stall in first gear . with your 2200or2400 stall bam your perfect for all around usage for cruzing and hyway driving , MY dizzy set up put me in 2 catagories big whole shots, frying the tires wildly like I like but no town driving
unless 2nd gear and coast under 3200 rpms or street drag and no hyway because the gears will put meat 4300 rpms at 70 mph , so no 20 mile drives or I will kill it, buzzing the motor and over heating or wear it out fast . well you have to play with it for your perfect driving condition , or get what feels wicked quick but just 2% over and I blew my motor doing 1 more run on the way to have it tuned on the dyno I burned 2 pistons and pulled it and took in to my builder hoping for the best. go search smoking out the left bank by winstoninwisc all my pictures show you what pre detenation will start at , not including engine internals. igot lucky and had a lot of FABO FAMILY HELP in the past few weeks. with trades , sales , and donations because these people care to help you out, and know they get any help or favors back 3 fold , with my hoard now open to any gold or better member , or can prove I or we are the kind of people we want for FAMILY.
