    Suggest engine mods for my LS1 project (budget)

    I am putting a LS1 in a 1985 Corvette:

    Specs:

    4L60E trans
    3.07 gears
    313 30 rear tires

    REQUIREMENTS:

    1. Mid to low 12 second 1/4 miles
    2. Smooth idle - (wife will be driving it to work for a while)
    3. A/C functional (no running hot problems).

    I currently have a 1998 LS1 stock with an extra set of 2000 center screw LS1 heads and a complete 5.3 for spare parts. My intake is a non-EGR LS1 intake. I will be running shorty headers, no cats.


    BUDGET IS CRUCIAL - Used parts, ZO6 parts...etc, are all good!

    no2 done right !

    Cheap and proven to go high 10's on a stock engine when done right

    GMHP had an article of a lt1 running low 11's with less then 4k i think

    TSP Rumbler, LT's, TSP Tqr2, PRC 921 Springs, Comp Lifters, Chromoly 7.4" Pushrods, Titanium Retainers/Seats/Seals, ARP head bolts, BMR full Rear suspension

    He just wants to run 12's, N2O is definitely overkill for that. Personally I would never run Nitrous through my motor, just doesn't seem worth it to me, no matter how much faster you can run while spraying.

    Some good mods for the '98 motor you have:

    LS6 Intake Manifold
    Long Tube Headers (Pacesetters are $289, if they will fit your car)
    Stall Converter
    Shift Kit
    Tune
    Throttle body Bypass Mod (Free)

    Those mods should easily put you in the mid-low 12's

    Are the 806 heads the perimeter screw heads from 97-98?

    Lower gear in the rear-end should help and can be done fairly cheap. 3.73 should have you at peak RPM at the line.
