305tbi
Ok i have a 305 tbi L03 in my 89 maro, and I wanted to ask suggestions on mods beyond most of the basics.. heres what i have now
14x3 oe intake, edelbrock headers, flowmaster 3" exhaust, hypertech chip, msd cap, coil, rotor, and super conductors... i have a 9 bolt l/s disc rear.. what would you guys do next, and what kind of quarter miles times would u expect with what i have so far.

Get the torquers, for $720 assembled, they'll support .540 or .560" of lift with the springs, not to mention they're 50 state street legal. The Vortecs require a different bolt-pattern intake, they headers will be raised about .100" due to different exhaust port placement, they do not have the passages for EGR, so you'd have to route the gas from one of the headers like the Vettes do. As far as intakes go, to keep the EGR I'd recommend the Edelbrock TBI one. Sure it doesn't flow as good as the Performer, but it maintains the stock EGR valve. I bought the performer/EGR and noticed the mounting flange for the Performer EGR was different than the one for my stock EGR valve. I still haven't found what kind of EGR valve this manifold was designed for.
All in all, with the S/R Torquers or Vortecs, a decent intake, and a good cam, I'd easily expect to see 80-100 horsepower.
Keep in mind, after adding the heads, cam, and/or intake, you'll need a custom chip to make things work together. Bigger injectors will probably be in order too.
After you've made the power, I'd guess you'll need some LCAs or a better torque arm to help put that to the ground.
As far a 1/4 mile times, I'd say take 1-1.5 second off your best. Just guessing though.
Just some thoughts,
Jason
