No Limit or PorterBuilt or What?

[slowcpe]

NoLimit and Porterbuilt's coil over kits will be roughly the equilvlent to a 6/4 drop, not necessarily ground-hugging. Both would be great kits to give you much improved handling and ride. Ridetech's coil over kit may be a little less invasive and offer similar results.

400hp to the wheels will be a decent task to achieve through a 4l60/4l80e trans. Easier to accomplish through the 60e but may be at its limits. To help compare the modern transmissions think of the 4l60 as a th350 and a 4l80 as a th400 but with an extra gear. The 6Ls are 6-speeds.

My current planned combo is a an lq4 (lower compression 6.0) w/243 heads (same head as factory but smaller combustion chamber to bring compression up), decent size cam, bigger injectors, necessary odds n ends, and a t56. That should get me over 400hp to the wheels. If I run my 4l80e instead, I'll probably looking at 360-380 and a 3400-3600 stall.

Any more power and I'm looking at a lot more money or going turbo.
