i have advertised dyno graphs for the edelbrock 347 (using the rpm xtreme heads) and the t&l 347 (using dart pro 1 heads). its not gospel, nor is it my engine, but its an indication. by plotting it into excel with the trans ratios and shift points, its clear that the darts give up more hp/tq from the 1-2 shift than the edelbrocks. if i could get a dyno graph for something close to what i have, i'd like to plug that in and see what it looks like. Nitrous SSC, do you have a dyno graph for yours n/a? what intake and cam are you running?
also, TS 95Cobra, i do have the torque monster headers (large collector version) and the 4r70w trans (i think thats what you menat by r4700w). its got a 45% drop in ratio from 1-2. that is a killer in a heavy truck with lots of wind drag. i am thinking about shifting 1-2 at 6500. im losing power going past 6k, but gaining power on the upshift. if not, i need an engine that makes peak tq at about 3800, cuz shifting 1-2 @6k drops me to 3250.
the engine has an aftermarket intake on it already with a larger tb and lmaf. i talked to art carr last night about the torque convertor. they said any stall is going to suck for heavy towing, but any power cam is going to suck without a stall. arrrgg!
