I must say, this is an awesome site. any little piece of information i have been looking for is here. I am in the process of building a 78 c-10 p/u swb. I have aquired a 5.3 engine (no idea what year or mileage). The engine now sports an edelbrock intake, a blow thru 600 holley, and as soon as i get the cheese saved up, a garrett gt35r turbo. I am now working on polishing the heads, intake, valve covers, and timing cover. (i also do polishing on the side if anyone is interested pm me). i look forward to taking in all of theknowledge that surrounds this site.
