Thanks for the advice!
Well, my driving habits are around town @ 30mph, then highway usually 65-70mph, occasionally 80, 85. I might then pass someone at 80mph in 3rd gear, and that would be the highest the engine would ever rev.
Correct me if I'm wrong, but looking at the calculators for the AOD transmission with 3.55 gears and 225/75/15 tires, and it's showing life mostly lived @2000rpm, and passing someone at 75mph in 3rd gear, my most extreme driving style, is still only 3200 rpm?
I'm wondering now who pulls 5000rpm and when :-) I guess racing is another world, and you don't risk a cop's wrath at only 70mph.
I'm looking to wake this car up a little, so the engine doesn't lug in overdrive going up gentle slopes on the beltway, and so it doesn't feel so very sluggish when I put 600lbs in the trunk. Adjusting the tv cable should help with that... and the dual exhaust with shorties (instead of stock grand marquis headers) should do a lot.
Anyway, sounds like I'll be just happy with the HO intake for a while, that what very minor gains from the gt40 at lower rpms can wait a few months. This whole engine rebuild + exhaust is costing $1000 as it is. I already have the HO intake, it wasn't a choice of $140 on HO OR gt40, in that case there'd be no contest, it's $0 or $140 gt40 :-)
On the explorer cam... I'm interested. Anyone have one to give me?
However, as it is I'm planning to swap to the lincoln mark vii speed density computer, will plug right into my grand marquis harness and the lincoln had the HO engine, and thus of course HO timing; so it would be an easy transition, and I have two very clean HO camshafts on my workbench already... if I get the explorer cam, would i need an explorer computer and maf?
