Well as most of you know I recently purchased a 1985 Chevy C10 about 2 weeks ago or so. It has a 305 with about 135,000 miles on it. The guy right before me drove it ALL the time and drove it hard with a huge tool box in the bed loaded with tools and a big trailor he hauled around on jobs. Well it's in really great shape but on start up it blows out smoke and now starting to blow smoke when you drive it. It's running really rich and then also not just rich it has a weird burning smell to it as well and it is VERY strong. Stand behing the truck for not even a minute and your clothes smell. My father thinks the rings are going on it. So here is what me and him would like to do. Instead of wasting the time and money on getting a new Edelbrock or Holley carb and manifold, headers, rebuilding it, etc we thought we might as well put a nice crate 350 with all that on it already. It has a 305 in it now with a newly build 350 tranny with a shift kit and that is all. This is the everyday driver so I mean I don't need a Edelbrock crate with 450 HP or nothing but about 300-350 HP would be nice my father said.
Any suggestions on places you guys have used and gotten good service and a good 350 4 bolt main crate motor?
Thanks a lot for any help, suggestions, comments, info and whatever else!
