So its that time of year again to start planning my usual winter upgrades, which this year look like theyll be more extensive than usual now that ive sold my house. One of those upgrades may be an 11/12 gt, hence i still have somewhat of a budget, and i still need to rebuild a trans (either the current t5, or the original aod), either a clutch or converter, get some drag radials, and rebuild the trac-lok, along with some other odds and ends.
Anyway, I'm looking into getting my wedge heads fixed up (some of you may remember, my cam bolt backed out a few a years ago and bent every valve, oops), and i figure while im there ill do some other things, which is where i run into questions:
1) I'm looking at maybe swapping out my tfs stage 1 cam to a used (if i can find one) comp xe274, i have the upgraded dual springs in the heads already (bought in 2008, looks like the new upgrade springs are pacs, no idea what the older ones are). will this be enough spring to handle that xe cam up to around 6k or so, or should i spring (hey, look at pun) for the new-style pac springs that look like they keep the same retainers etc, or should i be looking at something else entirely?
2) PTV clearance-i know i'll have to check this to be sure, but what are the actual chances that the xe274 will clear with my stock explorer short-block?
3) My backup plan to finding an xe274 is an xe270, whose advertised duration and lift numbers are much closer to the tfs cam i have now, so would it even be worth looking at swapping to the xe270? Would it even offer a driveability increase over what i have (which i cant get to idle at less than 1000rpm by my not-so-trustworthy stock tach, at least not without stalling when braking for a stoplight/turn)?
4) Car currently has a tfs street intake on it, and i dont know if it would be worth it to swap out to something like an rpm2 or a systemax (used of course, if i can find one). I WILL be swapping my mis-matched 65mm bbk tb and 70mm summit egr spacer for a 70mm accufab setup (maybe a 75mm if i do end up getting an intake that will support it)
