CASTING NUMBERS: Don't mix casting numbers up with part numbers. They aren't the same. The numbers in Performance American Style etc are part numbers, you won't find them on the intake.

1) On Dave Crook's 70 390 4v (not a machine) intake: 319 5532

2) Blaine R. Hertzog in 1999 noted that the original 4bbl manifold that came on his '71 SC/360 Hornet has a number of 319 5532 C. He adds that it seemed there was nothing special about this manifold; and he was sure it is the original as he was the original owner of the car.

More to be added shortly.

*** Pierre Bochamp / AM Racing Enterprises ***
**********************************************

New Single Carburator Intake Torker Killer: It's the best and most flexible Manifold in racing today, and very impressive. This Single Plane has an altered short radius runner to give the Air/Fuel a straight shot at the intake valves. NASCAR Style. (This is straight from his catalog, I haven't seen this intake)

Pierre also offers custom made sheet aluminum intakes. These are 2x4 Prostock units built to your specs...

AMC 290-401 V8

PERFORMER AMC (IDLE-5500 RPM) ******************************************

Designed for 1970 and later street 290-304-343-360-390-401 c.i.d. V8 engines. Available with or without EGR. Will not accept stock Motorcraft spread-bore carburetor. #2131 is a stock replacement/street legal part on 360-401 V8s with OEMcarb; 1970-72; except stock equipped EGR. See Power Package Graph.

Performer AMC (non-EGR) #2131
Performer AMC (EGR) #3731*

Product Review, by Ron Waters : The Performer is a significate improvement over stock cast iron AMC manifolds above 3000 RPM. Both stock and Performer perform about the same to 3000 where peak torque for both is reached, the Performer peaks about 20 ft lbs more at 3000.. above 3000 torque falls for both but at 5000 the Performer has about 60 ft lbs more than the stock manifold. Keep in mind these figures will vary a little depending on engine cid. The Performer works well on say a 343 or 360 to 5800 or say but a 401 could use bigger runners at 5500. Sometimes a spacer will help a little one 401 at higher rpm. We run a performer on the 401 9.5 to 1 Spirit with 750 holley double pumper ..Granted both have been slightly modified and work great to about 6000. Also the intakes performance will be highly affected by carb, cam, valves, intake and exhaust runners, combustion chambers (which are shrouded on big valve AMC heads), and exhaust system. Everthing must be matched for the best results.

I have heard people on this list say a 600 cfm was all a 390 needed.. I ran two 660 cfm double pumpers on a 302 cid engine and it was awsome.. thats 1320 CFM!!!!

It is my opinion that the Performer is an excellent manifold especially with a few minor mods. for the use it was intended: 0 to 5500 RPM's.

TORKER AMC (3500-7500 RPM) ******************************************

Designed for street and race 343-360-390-401 c.i.d. V8 engines. Manifold not equipped with EGR. Manifold will not accept stock Motorcraft spread-bore carburetor. Not recommended for 290 or 304 V8's.

Torker AMC 1967-69 (non-EGR) #2935*
Torker AMC 1970 and later (non-EGR) #2930*

Product Review by Ron Waters : The Torker IS still called the Torker and is far superior to the stock, Performer, or R4B above 3500 RPM's and will also pull another 1000-1500 RPM's than the others... Being a single plane manifold it does not have as good driveability or torque at normal speeds (below 3000)..

OBSOLETE BY THIS MANUFACTURER:

SP2-P ******************************************

Description:

R4-B ******************************************

Description: This designation stood for Rambler 4 barrel. It was supposedly patterned after the Machine 4 barrel intake. Versions were made for both the gen II (66-69) and gen III (70-87) V-8's. Both versions were also available from AMC with an AMC part number stamped on them (66-69 448-5731; 70 & up 448-4410) -- making a total of four versions of this manifold.

NOTE: Bob Kowalski says he has a different AMC part number number for the Edelbrock R4B: 448-5729. He does not know if this is correct; and will check. "Blaine R. Hertzog" in 1999 said he had installed on his Hornet SC/360 an Edelbrock R4b with a part # AM 448-5729 which matches Kowalski'. Hertzog also says there is also a "71" stamped in the manifold forward of the carb mounting pad; although he speculates this may have been done by someone other than the manufacturer.

According to Dave Crooks / : R-4B is NOT patterned after the Machine Intake, although a lot of people seem to think it was. Performance American Style helps to confirm this, stating that the R-4B has better power above the rpm range of the Machine intake. I've talked to several people with both, and they confirm the R-4B is roughly an inch taller than the Machine intake. Although I haven't confirmed it, I strongly believe that the Performer is closer to the Machine intake, and the R-4B is one step above both closer to a Performer RPM.

Product Review from Ron Waters : The R4B in my opinion is the best of the 3 producing more torque and hp than the others, especially at higher RPM's.

CROSS RAM: STR-11 ******************************************

Description: available through the Group 19 system from dealers, and direct from Edelbrock. To my knowledge it was offered for BOTH Gen II & Gen III engines. AMC part number is 448-6228 for 66-9; and 448-8411 for 70 & up. Made with flanges for two holley carbs.

The Edlebrock cross ram intake model designation is STR-11 It was available through Edlebrock as the STR-11 (67-69) or STR-11-70 (70 and up). STR stands for Street Tunnel Ram

DUAL QUAD ******************************************

Description: Dual 4-barrel.

TUNNEL RAM: UR-18 ******************************************

UR-18 Tunnel Ram. The UR in UR18 Stands for Ultra-Ram. Anyone have AMC.Edelbrock part numbers?

Single 4 barrel intake. Don't know anything about it other that it was cast of magnesium and was used by the PENSKE Trans-Am Javelin team.

Dual In-Line. Questions for this one -- part numbers, availability, AMC versions, etc???

Bob Kowalski aka "The BlackWidow" has made a dual-quad tunnel ram for AMC's from scratch, from aluminum plate and tube.

Didn't Fred Brewer or the fellow in WV have a sheetmetal manifold for AMC's? If you know anything that is or was available in the manifold department, PLEASE send it in to me!

AND NOW FOR A MANIFOLD INSTALLATION TIP From Phil Campbell :

Thought I would pass this along to anyone who is interested. When installing the intake manifold on your AMC V8's, I use the full valley
gasket, the metal kind that runs from one head to the other. If any of you have used these in the past, you know they can be a pain to get in the right spot, then when you drop the manifold on, you find it has shifted and the holes no longer line up. Heres what I do...

1) cut about a 2"x2" notch at the front of the gasket (facing towards the timing case). This clears the metal casting where those allen bolts are and makes flexing the gasket much easier.

2) I apply the gasket sealer, RTV around the water ports, and the black sticky stuff around the intake ports, on the head side only. Then I take the intake manifold bolts and put a nut on each of them and thred them up part way. Put the gasket in, line up the end holes, and put a manifold bolt in each corner. Don't torque them down but thread it solid. Then take the nuts you put on and losen them until they are holding the gasket firmly. Use the rest of the manifold bolts the same way, thread them and then loosen the nut until it is holding the gasket firmly against the head. I will usually leave it sit this way for either a few hours or overnight. Then, when you pull the manifold bolts, the gasket stays right where you put it. Put the sealer(s) on the intake side of the gasket, plop your manifold on, and voila, every hole lines up...you can even thread these babys by finger most of the time. Having done this no less than 4 times this month, I think I finally figured it out.

Hope this helps...someone....somewhere....

Phil (I have way too much free time on my hands) Campbell
