Is the pto in the tractor still? Depending on what rpms you run, you may possibly be able to dyno it off the direct engine side of the dyno. Just be extremly careful at that rpm if it is over 4000 rpm on the dyno,, As far as an injected fuel,, NOS would be a good solution if it is allowed,, most rules will not allow a pressurized fuel system much past an electric fuel pump. What kind of carb and intake are you running?? Older buick 350's have alot of parts available for build ups,, dual quad intakes for lots of torque, or smaller single plane intakes for high rpm, and lower end torque. Most part of this is that you have to be able to work that engine hard enough to see what the fuel delivery system is doing when it does lug. Also, try to stay away from vacuum secondary carbs on pullers like this, it is only a delay, and sometimes you get into tracks where you may not get the secondary to open correctly,, so a mechanical secondary carb would be a good choice,, it opens when you tell it to, not when the conditions are right, or too late.. A holley is a good carb,, of course, so is a quadrajet carb as well, the old rochester carbs you can find them off of the big block olds, buick 455's, or cadillac 472-500 they are 850cfm right off the engine, some of the best carbs from the factory were on these engines. also, a stall converter if you are running an auto matic tranny with the tractor rear end.. maybe a 3000 stall might help get you off the line better, and the higher rpm off the line,, you can get the rpms up faster on take off. Buick and olds 350s are a good torque engine, especially at lower rpm speeds,, but were a low compression engine as well. even the rocket engines were under compressed for the potential they had,, Just my 2 cents,, ChadS
