Parke has built one of the nices Manx' you're likely to find. In the pictures below, it has a 2387cc motor with Autocraft heads and 51.5 IDA's. The car features a narrowed beam, raised motor and tranny, pro-street interior with dual Beard seats and Autometer Ultralite gauges, all done by Parke. He has assembled this car from the ground up.
Parke brought the Manx to Big Wig Race Cars for a roll cage, wheelie bars, and overhead switch box. The roll cage was built with TIG welded DOM tubing and was designed to hug the body as close as possible for maximum interior space. The wheelie bars are chromoly.
The finished product is seen below. Sorry, I don't have any "under construction" photos.
