thanks sam,mild talks to bob madera alot and when discussing my lifter delema with bob,along with john callies they both said that the street lifters my normal parts guy talked me into buying were not right for the spring pressures and rpm,s my engines have so i decided to bite the bullet and change them to the racing lifters that i was origionally going to use.bob also recomended going with the heavier wall pushrods.at first i could not grasp how a .080 wall pushrod could be bending but when it was explained to me what a spintron was seing i decided to upgrade to the .135 wall pushrods.the atmospheric conditions were a lot better today than they were on my last dyno session but i do feel that the changes i made did help a little in the hp department but the peace of mind having the correct parts is the big reward.i want to thank mild thunder and icdedppl for their help today.dan refered to us as THE 3 AMIGO,S.one thing is forsure ,we do help each other and we all learn from each other.

Nice job guys! That's really cool that you get your whole crew together and go to the dyno. Seems like the blood swet and tears pay off a little more when you have your buddies around and your slapping high 5's. 2 questions. How good were your quick fuels out if the box? And how big a lift cam are you running?

we did do some jet changes but in the end we are jetted almost exactly as they were when i took them out of the box,imo the quickfuel carbs are the way to go.i know it sais crane cam on the dyno sheet but that is not correct,these are custom grinds from comp cams 648 lift 256I 270E at .050hyd roller.in the future i will consult with bob madera for my camshafts unless the build warrants a shelf COOKIE CUTTER cam.
