sandblasting engine

We did it once..... on a non mopar smallblock motor and it looked great.
The best advice I can give is, to use some lacquer or enamel cleaner (some guy's like to use brake cleaner) on any surface that you are going to seal up using tape. Duct tape is the best to use, get a good grade of tape, as they make different grade's of it. The most important area of couse.... is the intake manifold carb flange and exhaust port's. When we taped our carb flange off, I run the first layer of tape one direction, then a second layer the opposite direction. then cut off all overhanging tape with a razor blade. Take your time, then it will come out good.
