90% of the engines I modify are Picco .28's I have done a JL .21 for a memebr named Scrogg, he loved it but hasn't been around for quite some time, I'm kind of worried about the guy. Click on my banner if you want to check out some testimonials, one of my Picco .28's won the National Championship for monster truck in Australia. Couple a Picco with one of my hand made pipes and you have a combo that nothing can touch according to my customers.
