cam swap, longtubes, porting....

[kingc]

I will be having the heads ported (stg 3), a cam swap, new springs, valve job, and longtubes. after reading my sig is there anything that you would suggest I do also power/motor? Does Mac make a prochamber to work with bbk or kookes longtubes?

Thanks. I gotta break the 300 mark with this. btw I would rather stay NA.

prochamber will mount to BBK's not sure about the kooks... plan on turning 6200-6500 if you get some big cams like the xe270ah... but i would go with a set of vt stageII cams since your getting ported heads... those mods along with normal bolt ons should net just over 300whp.

what's the highest N/A power anybody's had so far? and do you have to worry about snapping rods if the cams let you rev to high?

I have been told that the max for the 4.6 is abt 400 hp before the bottom end
Should be replaced

you sure? i remember hearing it had to be modified for the prochamber to bolt up to the bbk's

I hope your going with at least a stage 2 cam for your ported heads. They were well worth it. Don't know about your exhaust question. sorry. I have Mac header with prochamber and they work well with the occasional tightening.
