So I'm going to overhaul my 225 slant six I wanted to know all the performance parts I can put inside the motor while its apart . I want it for a racing and would love some ideas on new performance parts inside the engine I should put in it please help me out gyes tnks:)

Welcome aboard! Before we can answer your question, you should give more specifics.

What is your budget for the engine (and related drivetrain) build? Is this a drag only car? Street/strip car? Road racer or autoX car? What perf numbers are you after and what is your car platform? How heavy is the car? Preferred transmission type, and converter stall if you will use an auto?

If you can give us more info based on these questions, that would help a lot towards giving you sensible recommendations.

Best wishes and Slant on!

Lou
