wuz up gentlemen! i am getting closer to the time to begin my swap so im looking for some parts and blue prints on how to do this, i read the sticky up top already but didnt know if we had some more advice i could get....how long would this swap take? could 3 mechanics do it in a all nighter? how much POWER will i gain from this? is there a certain way i should do it to achieve max power out of it? what list of parts should i start buying first? Thanks

Re: 3.9 TO 4.2

Well for all the stuff you need talk to Tom over at Super Six Motor Sports. he has everything that you will need to do the rolling assembly upgrade. But i definitely don't think this is a plug and play job and can't be done in one night. Best to send the engine out for machinin, honing, etc. i am not sure of the increase in HP but Tom would be able to fill you in on those numbers if you call him. good luck with the upgrade.

3.8L with Forged and Balanced Internals,65mm BBK Throttle Body, JBA Headers, Mild Cam, KN CAI, Port/Polished Heads, T5 with GT Clutch, Steeda Short Throw Shifter, 180rwhp/200rwtq, Foose Df-5 18", 14" Roush Alcon Front Brake Kit
