Good to see you got it sorted. Were you still using the 1 3/4 dyno headers.

OK shimmed the lifters solid, put the HS rockers on. Valve train issues are gone!!!!! Made 751HP at 6900 and 602LBFT at 5400. Everything is happy and this thing is going in the car. I was really hoping to make closer to 800HP but I think to get another 50HP is going to take getting a little crazy with things. I am not willing to spend anymore on this deal. Hopefully I can get the car together by the end of the season and make some hits to backup these numbers. Well, I guessed 740hp....But I had seen a very similar build. Congrats...

Took the car out for the maiden voyage Saturday. Air was terrible 90 degree heat high humidity and for some reason I never checked my throttle operation before going to the track and it was not opening all the way, I have to get that figured out I am losing about a 1/4 of travel. The car still went a best of 10.07 @ 134. Not bad for an all steel including the scoop 65 Coronet. I think the ET and MPH backup the horsepower numbers and it still has more in it. The scales were not open so I couldn't weigh it but I am saying it probably weighs 36-3650 with me in it. Congrats on the 10.0 , sounds like high 9's next outing.

420 cubes and they are Harland Sharp rockers. The Harland Sharp rockers are fine you just have to shim the lifters solid. The way the Gen 3 Hemi oils the lifter these rockers will not work with a Hyd lifter. Any issues with the Harland rockers ?
