Even with the differences it is well worth using the Magnum head for your performance or race small-block build. These heads are readily available and offer the best power potential of any factory-produced head. Intake manifolds and performance rockers are available from several aftermarket companies and really wake these cylinder heads up. Magnum heads also respond well to port and bowl work, making these heads an excellent choice for your next small-block build.

i have a free edelbrock performer it says 318/360 on the top. Is that a good intake? its for my 340 the price is right but I wont use it if its a POS

Back to the original Question:
The Performer is a great intake,on a 318.
For your 340 the Edelbrock RPM or Air-Gap will be hard to beat.
I give the LD 340 a close 3rd.
Cool ?
 
As someone, I believe Wild, mentioned, the performer works well IF you do some work at the openings.

One member has a port matched performer 318/360 on a 360 with rhs heads and IIRC a xe275hl cam and it made 425hp at 5700rpms and 424ft lbs torque at 4200 rpms. Same engine build with an Air Gap, made 427 at 5600 and 442 at 4600. The intake works fine as long as the port opening is expanded a bit.
 
I was skeptical until I saw the results.

Free + maybe 100 in port matching.

Sell free intake and find a good used one, you are about the same.

Buying a new AG cost more plus the potential that it needs to be milled to fit, which seems pretty common lately. Might have to mill a used one too...

I have been out of the loop for a while and just getting back into it again. Is it a factory flaw that requires these to be milled?
For the money these cost I would hope the tolerances would be accurate. :banghead:

I picked up an Air Gap as well as the non air gap version. I have three small blocks I am trying to get on the road next year.

I have used the first Performer and thought it kind of fell off as far as power goes right around where they said it should, I have also used the LD4B and the LD340 and I really liked the LD340 but that was a dozen years ago.

The performer has its place on a less than 300hp engine but needs to be gasket as great as the air gap is it does give up some bottom end under 2500 and on a car like my 5th ave that's were it spends 90% of the time.
 
crap i just thought of something, i can not use a dual spring on my stock heads can i ? i want a cam and spring combo kit
 
LD340...so good that if you have one, going to an RPM Air Gap isn't worth the extra money. Another good intake is the Performer RPM.

The '71 and '72 340 stock intakes are actually pretty good. Don't overlook carb spacers either!
 
But single springs can't handle the rpm as well, if duals are recommend with the cam I would use them, no big deal in modifying the head...you be giving up rpm and power..so why use that cam in the first place if your not going to use the right springs ?
 
ok, well this brings me back to one of my other questions LOL!! sorry guys, i have a set of fresh magnum heads with new i believe dual springs and hughes 1.6 rockers. should i just bolt them on?
 
wow you would think you guys have edelbrock stock... lol

Heck you would have been better off buying the old Edel intakes, the D66's, the LD340's then any automotive stock, ha ha

Those went up in price while the auto parts markers all went bankrupt, lol

I ran that intake after I had an old holley street dominator single plane on it. Here is my take, yes lower rpm did have more power and it did idle better but after 5,500 - 6,000 power nose dived compare to the old holley intake. I could take off faster from a dead stop with the RPM but I missed the wot scream the holley had....that was the last intake I used up to the D66 and then my 318 spun a rod bearing and I got a 340 short block to replace it..had 360 MP heads already on the 318...I never ran any other intakes on the 340 block

I had no room to try any spacers on the RPM intake
