I like most of the suggestions here. As far as gears and a traction lok, it may be just as cost efficient to try and get a 8.8 out of a junkyard, many pick-ups, SUVs, or street tuned mustangs will already have different gears, and certain ones may even have 31 spline axels (much stronger than you'll need). One thing to remember is to build your car to handle the power first. Wheels, tires, brakes most importantly, and suspension, as mentioned before. Since you plan on staying NA, depending on your bedget, Super Six Motorsports offers port/polished heads, intakes, cam options, 4.2 and 4.3 stroker kits, flywheels, etc. I believe it's 1700 for a fully forged 4.3 kit w/ your choice of compression and 1400 for stage 3 ported heads and intake with a cam. Probably more extreme than you plan to go, but they claim 90 HP on the stage 3 "power pak". Check out some of the gear threads for a link to a gear calcualtor. It'll let you know how fast your car can go in whichever gear at whatever RPM with the gear ratio and tire size of your choice (how I found out my car with a viper-spec T56, 5.13 gears and 315/30R18 drag radials would still go over 200 miles per hour in sixth at the 7,000 RPM fuel shutoff
