I am new to big blocks and for now I am looking for things I can replace just to restore any lost power or to increase fuel economy. The engine was rebuilt about 60k miles ago, but it looks like the whole vehicle may have been a little neglected. So far I have replaced the air filter, changed the oil and filter, run fuel injector cleaner through the gas tank, and finally changed the fuel filter. Any other suggestions? Thanks in advance!
