Mahle Pistons
 

Are Mahle powerpak pistons any good? this is the part number being considered -SBC250030F05-, or am i better off with a set of forged KB pistons, this is for an NA motor nothing to crazy, this is im getting a really good deal on the Mahles if i buy them.

The mahle powerpacks are very nice. They come with a nice (metric) ring set too. Very nice fit and finish, very consistent sizes and weights.
In my opinion, they are one of the best pistons out there for the money.

X2 we have used some in our circle track engines we have built and they are a very very nice piston to run.

Nothing wrong with the Mahle. I'm running them in mine.

I agree, they're a fine example of "you get what you pay for". Very good quality. :drool:

Excellent stuff.. Mahle is the manufacturer if "Clevite 77" bearings also..

I first became familiar with mahle on big german diesels I work on,very,very reliable and tolerances very close from piston to piston.
I started using them in my hotrod motors and have exellent luck with them,you can also call mahle and talk to a tech that is extremely knowlegable on this piston,avdvise on ring gap etc,I just wish they had double truac pin retainers from the factory,I like to use truac double ,flat to flat and that I know of thats not offered any more,just takes less time and in my opinion is a better way,but they are exellent pistons to say the least!!!!

I had bookmarked the Truarc site from a previous thread on lifter clip replacement, good of a time as any to post it:

Best pistons on the market.
There are some other good ones, JE etc. but mahles are an awesome piston have forged ones in my 406.
Most nascar engines are all stuffed with them.
