This may have been covered here previously but in your opinion who puts out the best small block Edelbrock heads, either CNC or custom ported? I have talked to Hughes, Indy, and a couple local head experts with mostly similar pricing and theories on performance.

This is for a race only stroker.

I'll get the ball rolling. How big will the engine be?

How much does the car weigh and what is your goal for it?

The specs are below....although my question is really about who is the best supplier.

416" 340 +30
4" Steel crank, H-beam
Dynoed at 575hp@6500, 550lbs torque @4700
Ported J Heads flowing approximately 270 @.600"
Gary Stinnet HP950 on Super Victor
Cam: 627"/637" 276/281 @.050"
3300lb A-Body
Low gear 904
5.13 Dana
4-link
16 x 33 GYs
Stock front suspension
10.40 @125.00
1.37 60'

The car works well the way it is currently setup. However, I am looking to push it over 600hp to gain mph when running Super Street and a couple tenths padding on a 10.60 index.

given your location, I'd talk to board member OU812, Brian at IMM.

other good small block porters: Jeff at Modern Cyl, and Ryan J at Shady Dell Speed Shop

If you MUST buy Edelbrocks get the IndyBrocks. I have tried both and I dont care what the flowbenches say.....the IndyBrocks were faster on the SAME engine...

Lighten the car. There's no way that duster should weight 3300# unless your 400#.

Brian at IMM is an absolute genius when it comes to small blocks. I have talked to Indy about the IndyBrocks but at close to $4grand I don't see the value.

I don't need to go the full blown Indy route because I don't need to pickup 100hp....perhaps just half of that. However, although the Eddies will give me less HP gain they are certainly not HALF the cost of the Indy kit. And as far as Shady Dell is concerned...I just can't get him on the phone in spite of numerous tries.

My complete IndyBrock kit was $2200 with rockers pushrods and gaskets....

Mark..

the Indybrocks are an edelbrock head that has the intake pushrod offsetted aka TA/W2 head. He is not talking about the Indy 360-1 heads, just an indy modified eddy head.

100% here.

I have been using Vic(S/ST3040)with great results.I bet by his questions he was wondering if an Edelbrock head would be able to support what you were intending to use it for.
Edelbrock heads can only move X amount of air,no matter who does the port work.The Indybrocks with their relocated push rod locations probably help since most porters crowd the push rod pinch anyway.

Using the trusty Moroso Power/Speed calculator, I have his 416 @ 495 HP and your 421 @ 520 HP.

I think the INDY version of the RPM is worth some power, espesially on
a 4"+ stroker. Keith's are as big as I could get with tubed pushrods and
I think it would be faster if I could have opened them up another .100".

I'd also consider a different cam on the 416.

based on your current performance,( heads you have already) i would expect a set of well done eddie heads to be 2.5- to 3 tenths better than what you have currently. Not to mention a pretty decent weight savings, that you can factor in as well.
knowing what i know now, and people i have talked to over the past few years, i would recommend the hughes head and the full cnc porting they offer. you are just going to have more uniformity cylinder to cylinder over hand porting, and hughes's cnc program is on the agressive side as well, they produce a nice head, a local friend just ordered a set for his 408 ...i dont see any reason whatsoever you shouldnt pick up at LEAST 40 horsepower over what you currently have, if not a little more.

there are other heads that obviously will offer a bigger gain( indy/w5, etc) but if your goals are as you stated above, the cnc eddie heads from Hughes are, IMO, easily capable of the upgrade in performance to suit your requirements.
they do a lot of work with iron heads as well, give them a call and ask their opinion of a max set of eddies compared to your j heads.

Vic, You port heads also?

Yes but, I try to stick with SB heads as much as I can though.

...and the heart breaker.

all right i have a question . what is the best anyone has ever seen or had a edelbrock run at the track. pump gas or race fuel just tell us what it was so we can compare apples to applesand race weight if you know it.

My Cuda ran 6.70 in the 1/8th on BOX STOCK eddys. 3000lbs 340 non stroked. 1.40 60ft time.

Pretty happy with the Eddies with just a backcut intake, a sharp valvejob and opening up the Pushrod Pinch, of course mines just a little 341 mini stroker so I'm not taxing them all that hard!
