Ok. I have just been challenged to a "grudge match" race at the local 1/8 mile track and need some advice. this other guy is driving a truck also (in case you didn't know, I am driving a 66 chevy w/ a sbc), but he has a 383 stroker. I already have a 75 shot on the truck but am thinking about switching over to the 125 just for this race. My question is, with the fact of my gas tank being behind the seat, should I use an auxillary fuel system for the nitrous? The motor is still running a mechanical fuel pump, and I have a holley red sitting in the garage. what do you guys think?
