click on the link on the right that says "power paks" they added one for our 4.2's!!

I can afford that right now, I am gonna give them a call reeeaaal soon here and find out some details

 

wow.... their stage 4 kit for the 3.8 got over 400 flywheel hp... just think what we could do with the extra 400 cc!

 

I have done some research on thier products, and I will be buying the power pack for the 4.2 in the next two months or so. They are very resonably priced our 4.2's should really wake up under the new heads, intakes, and cam. Good luck on your buying and tell us what happened after the install.

 

When I first emailed them about a 4.2 power pack ( almost a year ago), they said that while they didn't offer one,they would put one together for me.Apparently there is enough demand for 4.2 powerpacks for them to offer them without special ordering it(they have been offering it for the last 2 months or so)....anyway check out their forums while you are there.They are in desperate need of members.
good luck
