this is a 355 with a gm hot cam kit, vortec heads w 1.6 crane gold rollers, rpm air gap with 13/4 spacer. 4.86 gears, 31.10.50 w m/t. all this has got me down to 1.58-1.60 60ft and 11.74 1/4 mile and 115 mph. the timing at the time of these runs was 38 at 3600. have put a recurve kit in the dist and am going to mess with it at the track this weekend to see what will work best. am bringing up the rpm's to 2800 and leaving from there. any lower than 2500 and the hesitation comes in. it's a small one but enough to loose on the 60 ft time. the launch is hard enough to spin the rim 1/4 inc each time i leave. hope thats enough as i have to go back to work now
thanks, charlie
