So far I have a 528 stroker kit (440 source), using the girdle kit as well, pnp'd/milled 906 heads, around 588 lift on cam, going to be spraying nitrous too apprx 200 shot. Just a fun daily driver with some strip power, lol. I would like to know if I could still get away with mechanical fuel pump or need to go electric?

Thanks for he help.
