I hate to burst your bubble, but you'll never be the baddest guy on the street without spending a fortune to get there. For instance, when I was working at Firebird as a tech inspector, we had a fellow who would show up every Friday night with a turbocharged Supra. He drove it in off the street, changed to slicks and laid down mid 7 second runs at 180 mph in the quarter mile. It would cost you $50,000 to $75,000 to beat him with a pickup truck.

Now, you could have a lot of fun building out the rear of your truck with a 4-link rear suspension and a 9" differential, (about $5,000), while spending $12,000 to $15,000 for an 800 hp motor and fully built auto and converter. So, lots of fun for $20K, but no cigar.
