Tyler sold them both around Christmass. In my opinion a 3.3 is pretty light for a 598ci motor. 4 or 5l would be better. You would have to turn it up pretty good to get 950hp. And want the intercooler for sure. I think Hot to Go racing also might have a 3.3 used not sure if he sold it. And if you do think about Procharger a M4-M5 nothing smaller.

Try Tylor Crocket
 

Tylor Crocket just had one for sale on here,I had bouht the other one from him a couple of months ago.It came complete with fuel system and all for a 525 efi,it is going on a 500 efi and the only thing I had to buy so far is a thermostat housing that is different.The kit is in great shape.It was on here a few days ago.

How much would a used kit cost w coolers? for a 598 block?

I have a buddy that is selling 2 sets of 2.3 efi quad rotors w moac coolers. They have 5hrs on them.

If your interested, let me know. I'll get more info.
