    i will joe. i called shore motor sports, and he told me to start with a 70, then go to a 72. does that make sense? he also said that i should get the primiary going first.

    id like your opinion though

    thanks

    Well lets put it this way, on that camaro i was telling you about, it would only ping under heavy load( foot to the floor from a dead stop and when it got in to third gear it would start ). On that vehical i upped the primary jets 5 Drill sizes and the secondary jets 10 drill sizes to cure the problem. SO the way you explained it to me ,your getting it to ping just by power braking it. That is a much leaner condition. I would start with the 72s in the primary and do the 92s i the secondairys at the same time . Then retime it and see what you got .you may even need more than that. If you do the 70s 1st you will just have to take it apart again to do the 72s /forums/images/graemlins/doah.gif.Now the jet sizes i am giving you are based on the 68 primary and 89 secondary sizes you gave me. when you take it apart check the #s and make sure that they are what the book says so that we dont over jet it.

    Later, Joe
