Need some suggestions!

I had a '89 Ram 150 2wd with a 360 Throttle body injected. 3.21 gears. Stock manifolds, single exhaust, stock torque converter, ran 15.30's. That's pretty close to a Lil Red Express times. This, of course, would be the roller cam LA 360 with factory 308 heads. All I did was remove the cat/muffler for a better flowing muffler. Still single exhaust Y-pipe though.
