Thanks all for the help. I am running a 140 with electronic ignition, 260 cam... Typical 140... Runs good. I do drive 30 miles round trip five days a week freeway, but the issue is getting up to speed. Up to 40mph fine then the p/w shifts and nothing till 50 or 60 mph. I sourced a 64 with 389 gears, might try it out.
