I have tried to tune one Holley 750 DP that acted like what you are describing. This one had good drivability, made great torque but had nothing up top. Changed several things and nothing really made a difference. Swapped on a Quick Fuel 950 and it picked up around 0.25 in the 1/8th and acted like a different engine all together. Lost a little bottom end but it like to turn some rpm's now. I chocked it up to the metering blocks like you. Glad you made some progress. I've had pretty good luck running an out of the box Holley but I'm only about 100' at the most above sea level. One track we used to run at was 19' above. 5800' I imagine has to require some changes - that's up there. I think Warren Johnson said that the air is so thin up there that birds prefer to walk. Clay
