Hi, I need to buy racing parts for my 502mpi, does any one recommend me some one that can sell and give me advice ?

racingjunk.com is a good place to start your search then go to the retailers as long as you know what your looking for

What kind of "racing parts" are you looking for

me too!

Eagle or Scat brand steel crank & H beam rods. JE/SRP pistons. Theres no replacement for displacement.

look at new , some of the used stuff is more than new. save money and do your homework. know what you really need and not what sounds good. been there done that, bigger isn't always better

Try Eddie Young at Young Performance. He hooked me up with the right parts for my 525.

Eddie Young and Bob Madera are the best, you will save a ton getting it right the first time.

Not sure eagle or scat is the way I'd go for that. Spend a little more and get a much better product, Callie's, crower etc

What are your goals with the engine? Are you keeping it fuel injected? What horsepower are you looking to get out of it etc.
