Has anyone ever seen a E6SE-DD lower intake?? ive seen a million E6SE-DA lowers but I need to find a lower with the ending letters of DD if it exists? this would be on a 5.0. thanks
Why do you need it? What's the difference?
H.o. and s.o. lowers are identical.
If you're looking at part number they rarely match the engineering number actually on the part... Just another of Ford's WTF...
Is this for some porting project/needed for a racing class? If not and you're looking for a power upgrade from an intake swap just get the intake from a 96-97 Explorer (GT40) and use that. You'll be time/money/power ahead of a ported stock intake.
its for an NHRA stock eliminator car. actually need an upper that has the RF-E6SE-9425-D?D or RF-E6SE-9425-C4C. wanting to put an 86 mustang together and these are the numbers that I have to run. I don't even believe these cam on the Mustang I think they we on a cougar or tbird or crown vic. but its what ford turned into NHRA so its what I have to run. I also need a 58mm throttle body off one of these cars as well
I was mistaken that this was a lower intake part number not an upper cause they don't specify the 9425 part of the number
Any 86 gt (one year only) 86-88 tbird/cougar or 86-91 crownvic should have the same intake. Crownvic upper is reversed and uses a different throttle body and fuel rail.
I can almost guarantee someone here has one laying around. I just sped 3 three months ago. I will be swapping my stock upper which should be what you need in the next month or two if you'll still be looking then.
So you need '86 HO parts, may want to check the LSC Lincolns of '86 & early '87 as they used the same 200Hp 5.0 as '86 Mustang... None of the Fox chassis T-Bird/Coug were HO...
Really? I thought the 86 h.o. still used the e6 heads and smaller egr and throttle body.
The '86 HO does use E6SE heads, a 58MM TB & EGR spacer(SO are only 50mm, later HO 60mm)... The upper intake throttle body opening may be slightly larger than a SO, but smaller than later HO... I know it's at least size of 58 mm TB... Also had 19Lb inj and a slightly more aggressive cam than later HO(the 90s engines)
The one I had in a '86 GT with 5-speed & 2.73 rear would run 14.50 all day long and no doubt 14.20s with good traction(I had street tires, had to walk it out of the hole)... It did have under drives, 1.7 RRs, and a 2.5" cat back system... Those gave it approx .15 sec & 1 mph improvement in ET...
It'd slaughter new(then) '96 4.6 Stangs, sold it in early '96...
If you pull it off and it has either the C4C or the D?D last 3 i'd be very interested in getting it from you.
