V8 ofcours|||Depending on your budget, you can't go wrong with a Gen III engine. You can go anywhere from the 5.7 LS1 to the 7.0 C5R engine. YearOne makes a kit to put this engine in your car! (link below)
There are several advantages to these engines. First, the head design of these engines is superior to Gen 1 and 2 engines, especially for power on a budget. A traditional SBC has 23 degree heads, while a Gen 3 has 15 degree for better airflow. Second, the LS1 (5.7), LS2 (6.0), LS3 (6.2), LS6 (5.7), and LS7 (7.0) are all aluminum engines...and will shave about 150 lbs off the front of your car, assuming you have an iron block/head engine now. That might not seem like a lot, but believe me, you will notice the difference. Third, they are fuel injected and will give great throttle response and fuel mileage. Also, if you could find a wrecked car to get parts from, you could get an ECU, transmission and engine together and make life simple. Just to give you an idea about power and economy, my 99 Formula has an LS1 that delivers 440hp to tires, it has a 4L60E automatic, and 3.23 gears. The car will go 11.6 in the quarter all motor, 10.7 on bottle, and gets 26 mpg on the highway with the cruise set at 70...with the a/c on! The car now has 88,000 miles and has been driving fairly hard since 20,000. It has been well maintained, but not babied...it's still going strong.|||Ls7 :) isn't that in the new z06?
