In my opinion it is going to be tough, a 2 speed stadium truck with a 2.5R VS a big bulky MT with a motor that is about equal in power....not going to happen, especially if you are just racing up and down the street it is not ever going to beat it....not saying the JATO is the bomb but its got probably half the weight and the same power and its a 2WD 2 speed against a 4wd 2 speed so the 2WD is going to get up to speed a lot faster. You want to beat him get a vehicle that has got a better weight to power ratio. I don't even think a big block would help but it might, those JATO's are pretty insane fast.
OR option two--find the oldest nitro fuel you can--leave it in the sun for two weeks uncovered and offer to fuel his truck for him with your special go fast fuel...lol
if you can't beat'em--cheat'em lol
