next dilemma... stock 350 (crate motor). warranty almost expired now, so I'm interested in improving performance some. I tow a fairly heavy boat on occasion, so I'm looking for more low to mid-range power. I have a performer intake, and dual dynomax exh system w/ crossover. what lo $$ upgrades to my motor will make the most difference? I'm thinking about a hi-perf ignition system and a cam to start with. Any of you guys tell me which are the best value while offering the biggest improvement in performance? (improved mileage wouldn't hurt either!) Thanks for the input... GUZZLES GAS BUT IT'S FREE AND CLEAR!!!
