    Critical upgrades for 4l60e

    What upgrades should be considered necessary when rebuilding a 4l60e for 430rwhp na.
    I lost $1300 in an ebay deal from leveltentrans who I beleive is connected to coastal-transmission currently selling on ebay. Stay away from them.

    Sadly now demodded :(

    Sun shell. Stock is aluminum. You'll need "The Beast". It's made out of Stainless Steel.

    You'll probably want to delete Torque Management for the PCM and utilize a shift kit.

    You'll definitely want a good tranny cooler, especially if you're running a high stall torque converter.

    There are other internal mods that need to be done also...
    67 Camaro: K-K + 797-z (look it up), 454/Th400/4.10 12-bolt = 6mpg, PS/PDB/PW tilt, tach, gauges...

    2005 Corvette LS2/M6 Magnetic Red Metallic (What else would it be?) w/ Cashmere interior

    2002 Z28: NBM/Tan, MTI smooth lid, smooth bellows, !AIR, !cats, 1-3/4" QTP SS LT's, 2-1/2" TD's with X-pipe, MagnaFlows dumped at axle, custom welded SFC's, MidWest Chassis body mount adjustable T/A, 3400 stall, 3.23 gears (was 2.73). Tuned: 343rwhp/357rwt (before TD's). Best: 12.559 @ 108+, 1.73 60' @ 3500' DA w/MT ET Street DR's.

    Carbon footprint? CLOWN SHOE!

    as the old man said ^ a beast sun shell is a must. Also a corvette style input shaft would be wise. of course clutches are suggested also.

    clutches

    For a street strip car what clutches are best? Alto hyper pack, Z pac, Or blue plate special. I have a 3500 stall and run drag radials. I have a complete bmr rear suspension.
