I am looking to buy a set of pistons for about $400 they will be sbc on racing fuel with vortec heads. Any suggestions for certain brands.

the wiseco pro trus are nice and they run about 398 on ebay for flat tops.
i just got a set of mahle flat tops and they are VERY nice for the extra 58$ over the price of a pro tru.
both pistons come with rings so you'll save money thath way too.

We rebuilt engine with mahle pistons and rings after 10 to 12 races we still have lots of blowby from breathers like the rings never seated properly has any body else had this problem? We have not sent it back for refresh yet. The engine builder says he will use different rings this time. This is a 408 on alky.

i get them on ebay from midwest motorsports.

tim,
the metric ring pac that mahle has is sensitive to proper honing to seat the rings.
the block needs to be honed with a torque plate (with studs if you are running them)and to the proper finish. i think 400 if i remember right.

speed pro hyperutectics are for budget or starter motors
the Pro-tru flat tops are a great piston, helped build many motors with them in them. We also built a lot of them with speed pros which are a good piston for the price, but don't expect them to hold past 7500
