1Badx - This might be a more appropriate forum to get the facts sorted out on using cast pistons with FI.

Can you detail your exoeriences with the factory slugs - espevially the 6,1 - and superchargers....including any thoughts you may have on using a blow thru system?

I have no personnal experience - but was pretty much put off the idea when I posted on the LX forums by people saying they wouldnt last - that the top ring land would fail..

I would only be considering around 7psi at max.....so interested to hear your opinion?
