Building a street strip 81 z28 with th400, line lock, 392 stroker has 408hp at 5300 with 490 torque at 3600. Going with caltracs set up including shocks and a mono or split leaf. Still has 10 bolt posi.... full interior car. Thinking either drag radials in order to drive on street or maybe slicks and just throw on my current 26.6" street tires when cruising. Looking at 3.90 gears with this size tire...not sure I can go bigger with this little hp and wheel well size in order to go to 4.10 gears.... thoughts on wheel size, offset, and tire size. Thx.
