So I just bought a new rebuilt 87 5.0 HO roller motor. Complete 3 angle valve job. Crank polished. Clevite 77 rod, main, and cam bearings. Eagle rods with ARP bolts. Clevite performance hypereutectic flat top pistons. Sealed Power Moly rings. ARP main bolts. Renegade Head bolts. Melling oil pump and roller timing chain. Ford Motorsport E303 cam (.498 lift). I've been told the set-up should be good for 300 horse. I also just picked up a set of ceramic coated Sanderson shorty headers for it too. I am trying to decide on an intake manifold. The car will mainly see street duty with a very occasional trip down the 1/4 mile. Any recommendations? For what its worth, the car will be running a C4 ****** and the manifold will be topped by a 600 Holley 4-barrel carb. I've been eyeing up these two manifolds right now, but am certainly open to others: Edelbrock Performer http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_18668_-1 Ford Racing http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_608937_-1
I'd bet that the 'ol **** dyno would not be able to detect any performance difference between those two. In that case, pick either a. the cheaper one, or b. the shinier one, depending on your taste and wallet.
IMO the best intake for any street going 302/5.0 is the Weiand Stealth. Usually cheaper than both the ones you mentioned as well. Stealth is good for idle to 6500 and they aren't kidding. And it's a split plenum. Good for a street engine. My friend had a crate 302, a production spec engine, but with a B303 and he ran a Stealth. It ran 12.99 in a Ranger on 28" tires with 3.55 gears. If you didn't overbore the block the factory pistons were/are forged. I don't think you will get 300 hp out of the stock heads with just a 3 angle, but you will be close. Port the stock heads and you would break through 300 hp I'm positive.
I am running a similiar eng with a performer rpm. If you could find one a edel, F4B would work as well. I use the autolite 1.08 carb 480 cfm, works well.
What stall you running in the C4? If it's a little looser than stock then go with a performer RPM or Weiand stealth is a good choice. Bolt some GT40's or GT40P's on it and a xcelerator or victor Jr intake would make some great top end power (little loss of low end, but if it's alight car it would run!)
My vote is a Air Gap , There is also a toowongfoo copy of the it that works just as well. I have a Ford 5.0 roller motor in a 41 tudor with a 600 holley and it needs more fuel. We put one in My friends 64 fairlane with a b303 cam with a 750 holley and it runs great...
well jus for an insite on things my dad has a 5.0 fuel injected in his 28 tudor with nothin done and it slides around awhole lot but i also have a 302 in my 29 tudor but it wont see the streets till the nats in louisville
TJM73 had it right on the head--best bang for the buck is the Weiand Stealth intake for your 302. But what do I know I only ran a SB Ford powered rail for years.
We do lots of SBF builds of all sizes.... for a typical street motor (like yours) time and time again, the RPM Air-Gap makes the most peak and average power and torque over and above any of the earlier E-brock , Holley or Weiand intakes. If you don't mind the more modern look of the RPM Air-Gap it is the best bet for your street motor. -Bigchief.
The stock heads resemble that of a Mopar. while they are less restrictive they still have alot of restriction mostly on the exhaust side. with a little work you can fix a little bit of the problem. most of it is EGR p***ages that are in the way so you cant take a whole lot out of them. The Stealth is awesome for stock heads and a relatively mild cam you will be satisfied with it i think.
Get the Air-Gap and avoid the Chinese stuff. I like the fact that Edelbrock makes everything right here in the USA and has always done so. F China
Air Gap....its modern...but...its a killer. I ran one on my W motor...don't remember the $$$ difference btwn. all of these, though...the benefits may not offset the cost difference, in this case, though... on a mild motor, with stock heads, though...I would think you probably would not feel much difference with either of these. any of these should work out pretty well.
I agree, you can't beat MADE IN USA. I just mentioned the Toowongfoo copy, in case the $ was was a big issue. I've ran just about every intake made for SBF and the Air Gap is the best for higher hp engines. You are prob right on a stock headed 302 it's a toss up. But the roller engines with roller rockers rev alot better so I like the Air Gap for that application. And it may not be "Traditional" But is a Roller 5.0???? I was told that the FordMotor Sport intake is actually made by Edelbrock????? There is prob someone who knows.....
By looking at pics and specs from the Ford Racing and Edelbrock websites, it looks as if the Ford Racing manifold is the same as the Edelbrock Performer RPM manifold. http://www.edelbrock.com/automotive_new/mc/manifolds/ford_sb_perf-rpm.shtml http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=6361
which is almost identical to the first sbf intake the shelby,cobra,ford, and edel f4b. i have a air gap and like it but it is a t%#d to keep clean in the gap area.
I use to Mud Race in a cl*** that required a "Factory" Intake so a hunted down a 1984 Mustang GT alum intake and it looked a lot like the early elelbrock that said 289. And it run great. The 84 GT intake had the FORD Oval and Skript on the front of it, Looked cool. I'd like to find another one.
With all these recommendations for the Weiand Stealth, I think I'll probably be going that route as the heads will likely never be ported and the motor will probably stay the same. Seems to be the best compromise manifold based on performance and price. Thanks again for the help! Maybe in time the motor will get a small Weiand blower and all this manifold talk will be for not, but until then . . .
