stock maf on 402?
Response of the engine is a wake up call..
I have HP tuners but I'm over in JAX n my tuner kit n O2 WB are up in KC ...
After Labor Day my TA n kit will be here, at least I hope ....
BTW, My 402 popped 482 rwhp with a 85mm maf n a fast 90/90 n 317 reworked heads 231/237 cam 115LSA. After the SD, it woke up !! Never had it back on the dyno .
