You will have to change your heads, unless you are already running vortec heads or plan to swap. The vortec style stealth ram is put under the weiand name. It's an easy install, about 3-4 hours. Save your money and get a fuel rail kit with a non-adjustable regulator, then pick up a Kirban (spelling?) regulator because the one that comes with it sucks.

itsMikey

fer sure..thanks guys

so vortec heads are a must?

Tony89GTA

Nope they do make one for the standard sbc head. Also you would have to mod your hood to make it fit and even then it's really close.

stealthroc89

No for the Weiand brand, but the Holley brand SR will work with your heads. They have the Weiand listed as a substitute for the 87-95 heads, retarded. http://www.summitracing.com/parts/HLY-7540, this is what your looking for.

NY3RDGEN

Yes it will work.
Search Holley Stealth Ram.

itsMikey

Did you read the link I posted above on WHAT IS NEEDED for HSR install?????

You already have a computer/wiring / TB / injectors /etc

You only need the intake and fuel rails.

but dont i need the vortec heads for just base and plenum?

Orr89RocZ

iTrader: (20)

There is a stealth ram base and plenum kit for less than 400 bucks that will fit your L98 heads. Then need fuel rail kit for 200 more. Fuel lines to connect to hardlines custom made for 120 bucks or less in parts. That's it really.

Search for My holley stealth ram swap. I had a detailed swap thread with results on stock L98. Basically with exhaust headers 2800 stall and sticky tires I went 13.63 at 97 on stock TPI. Intake swap to hsr with drag wheels for less weight it went 13.2s at 101 in similar air. 1.6 rockers and pulleys with better air conditions I went 12.95 at 103.8

itsMikey

sick..always loved ur builds..gona find it now

stealthroc89

I didn't notice the link I posted shows summits out of stock right now lol. Thats the right part number though. By the time your ready to do it they should have more in.

itsMikey

yeah i was like..uhhh...lol

stealthroc89

Look in the classifieds here and see what you can get. Might get a good deal on a complete swap. ezip has one up for sale, you don't need all of the parts he's selling, so see what he will take for the HSR, Kirban and Fuel Lines. $400 would be a fair price, but as always start low!

Hey ItsMikey! Remember you can't pass smog with the Stealth Ram in California.

itsMikey

fer sure...ill check it out

itsMikey

totallyconfused -_-
yes or no...
do i need vortec heads for this setup?
http://www.summitracing.com/parts/WND-7540/

the link posted above to Summit says that the HSR IS this and that it just got renamed...

Tony89GTA

iTrader: (7)

Yes looks like they had a name change the link above would be the one for the standard sbc head. Part number Weiand 7542 would be for the vortec version.

itsMikey

so this is definitely what i want right? with the fuel rails as well...

VincentZ28

iTrader: (2)

Try this one...................... http://www.summitracing.com/parts/HLY-7540/
The Weiand is for the Vortec heads. You can find Weiand products on the Holley web site. They must be part of the same company or they have merge together.

stealthroc89

Holley owns Weiand, they put the vortec under that name to avoid confusion

Orr89RocZ

iTrader: (20)

yep thats what you want, for regular heads

Tony89GTA

iTrader: (7)

Vincent on that page it shows the part # been renamed now to WND-7540

stealthroc89

That would explain why they list the Weiand as a substitute. Just make sure its for standard port heads

itsMikey

thats what im saying, the HSR isnt the HSR anymore...its the WSR -_- lol so i want the WND-7540 that i posted above? cuz theres another one that seems to be for the vortec setup

Orr89RocZ

iTrader: (20)

vortec stuff is FAR different than your factory L98 heads. You dont have vortec heads so you dont need anything vortec. If you want the stealth ram for your heads or any other aftermarket head thats NOT a vortec then go with the part number above... 7540

Head spinning on this one!

itsMikey

^^^ me too -_-
lol..7540 is what i want tho
thanks guys

stealthroc89

WND-7540 for 55-86 heads, WND-7542 for Vortec Heads and I don't see a number for 87-95 heads, but the WND-7540 fits 87-95 aluminum heads (info from Holleys site). Is there a difference between 87-95 iron and aluminum heads that I'm not aware of? I contacted holley to see why they changed the brand, I know they filed for Chapter 11 protection 1 year ago, but who knows. Too bad they didn't design an egr in it with the name change, that would be sweet! They're also $15 more than when I bought mine.

itsMikey

i dont think there was a difference. i could be wrong tho...guess we'll see

anesthes

iTrader: (12)

87-95 aluminum heads have a different angle than iron heads. Remember when the Fbody, trucks, etc switched to the straight center bolts on the heads in 87 or so? Well the aluminum (corvette) stayed on the older pattern. New GM aluminum heads (ZZ4, etc) all use the older pattern as well.

-- Joe

Orr89RocZ

iTrader: (20)

Stealth ram should be drilled to accept both bolt angles. Heads 4 center bolts are either 90 deg or 72 deg angle. An oval bolt hole on the HSR will fit either one. Mine came with a oval hole to fit either one.

anesthes

iTrader: (12)

My Holley intakes came slotted/oval as well.

itsMikey

so it shouldent be a problem for me right?

Orr89RocZ

iTrader: (20)

Thats correct

itsMikey

thank

camaropower88

If I'm already EFI do I need to get the fuel rail with this manifold?

Orr89RocZ

iTrader: (20)

Need HSR rails for HSR intake. TPI ones wont work. Its possible that the edelbrock victor rails can fit too but you'd be fabbing a slightly different regulator package with that and have to make your own crossovers.
