Wheeling and Dealing it cost me $1900 to build a stock bottomed 302 Cleveland with all the good bits up top and $200 for a conversion kit that i heavily modified. That included extractors, exhaust, electronic ignition, transmission and blah blah blah. Think i've done around 450 hrs work on the car and would've cost heaps more if i had someone do it. As everyone says you can save heaps of bucksdoing it yourself. Having drifted to the dark side with the "heavy" V8 conversion i am still a big fan of my L28 triple carbed 260Z 2 Seater, i just love the sound of it revving.
