Hey All,
I've discovered that I "over-built" my 5.0 for my needs. Here was the originally executed plan:
>Brand new from Ford 99ish Explorer long block
>GT-40"P" heads
>Hypereutectic pistons
>B303 roller cam
>1.7 to 1 ratio roller rocker arms
>Performer RPM intake
>Autolite 4100-1.12" venturi
>Mallory magnetic breakerless distributor
>Tri-Y headers
>T5 transmission
Well, heres the story, the engine is a ball when my foot is in it all the time but that was NOT my intention for the car. It doesn't even start to wake up until 1500-1600 RPM (intake) and then REALLY comes alive at 3000 (cam/rocker combo) and above and is a true screamer. Part of my problem is that this car is intended to be my daily driver/cross country highway cruiser but still have enough poop to be fun. The way it is simply encourages me to drive WAY more aggressively than is prudent and is not practical. Not to mention fuel mileage (especially with my foot in it) is horrible. Best, gentle driving 11mpg in town and 15mpg highway, foot in it, welll.... WORSE! I want to give the car a little bit more low end/rpm grunt (more fun for my application) and don't mind sacrificing a bit in the higher RPMs. In other words, drop my power RPM range a bit. I have already swapped out the 1.7 rockers for some 1.6 to 1 rollers and that certainly took some balls out of the cam and made it a bit more docile, but still the intake kinda limits things a bit. I guess the main purpose of this post is to get some opinions on what intake to swap to, given all of the other details. I don't really want to start from scratch with a new cam, etc. I'm even thinking that an intake that actually has the coolant crossover at the rear might be a good thing, as I plan to spend some serious highway time including air conditioning and likely pulling a fairly light back half of a Mustang trailer. Maybe Edelbrock Performer 302 (3721) or something similar. All thoughts, comments, opinions and suggestions are appreciated.
Thanx,
Gene
