I just wanted to know if anyone has had similar results as myself with this product. I installed the stub stack on my Edelbrock 600CFM carb and actually slowed my car from a 13.2 to 13.9's. I even jetted up a little to compensate but there was no improvement. I run an extreme airflow top with a 5" K&N element so air cleaner restriciton is not an issue. I just had high hopes for this product and was really let down.

I put one of these on my edelbrock 750 and has similar relults, although I did not track my car during the test I could definately tell it was a whole lot slower. On top of that my buddy had the exact same carb on top of his 350 and it had identical relults. Now I have a Demon on there so I care no longer.

Calvin, it's been a long time! How's NC? How's the ZZ4. Tell me about your heads, I am thinking of porting mine.

NC's pretty good, I sold my ZZ4 heads and bolted some AFR195's on. It got me some 12.20's right at 117mph, but I just bolted on a demon 2 weeks ago and some cold air induction. I dying for an 11.99, with it getting cold around here I might just get there. Anything new with you?

------------------

Nothing really super new. I am probably going to move to Georgia. I would like to know more about your AFR heads. Did it kill your torque? How much differently does the engine react? Do you think those heads would be a good choice on my AUTO Camaro? How much did you get for your heads? Is porting ZZ4 heads and intake worth the 600 buck Scoogin Dickey wants? I would really appreciate your input, you are obviously hard core! I am dying to get to the 12's on a regular basis!!!

The AFR's didn't kill torque at all the only mod on the heads is that I had them milled to 54cc's to put the comp. around 10.5:1. I was a little disappointed at first with the results I only picked up a little better than 1 mph at the track but then I decided to put richer metering rods in the carb and I got about 2.5 mph more and then I was pleased. I think I got about $650 for the heads. I think the afrs would be fine for an auto. When I got my motor from Sallee they charged me $400 for the ported heads so check them out too. Are you running F/I if so what type? oh yeah you can also change that 3:73 in my sig to 4:10's as I put in a 12 bolt in march. How do u chang your sig by the way?

Sallee will not port my heads, I called. I have the Standard Abrasives porting kit and had the intention of porting my own heads. I am just sooooo worried about screwing up a 1000 set of aluminum heads. My intake set-up is an Edelbrock 600cfm carb, LOVE IT. I know where more power in my combo is, my exhaust. I just hate the exhaust restriction in these cars. Even with my TES I know 10-15HP is choked out by the single 3" y-pipe. I even run a 3" dump but it still is not enough. I wish I had your dual 3" pipes. Do you have any pics of your car I would love to see them. Gotta Go, Thanks!

Yep still here, been a little preoccupied lately, refinancing house and about 10 other things. I'll email you a pic. Yeah I think I could squeeze alittle more outta my exhaust also with the addition of some 1.75in. longtubes, but I love my new dynomax mufflers, they are alot quieter than the flowmasters. I went back to the track and got a 7.80 in the eigth and 12.10's inthe 1/4 but ended up toasting the clutch, damn I want some 11's.

------------------
89Camaro,ZZ4,ported heads,LT4 HOT CAM,Victor Jr,T56 6speed,3:73's

 

Calvin, to change your sig just go to the top of this posting, look under "post new topic" and click on "profile".

Are you running shortie headers with dual 3" pipes? INTERESTING! Long tubes are in order. If your clutch just gave out then a centerforce should easily get you into 11's. I have decided to go with an Edelbrock RPM air gap intake and have my ZZ4 heads ported. Sallee says this should be worth 420HP! If that does not get me 12's then screw it, my exhaust is just too restrictive. Still debating going to larger valves.

I move to Georgia on Tuesday. I would like to get a Southeast gathering set up so thirdgenners could kick it and bullsh!t about mods. Maybe meet in SC somewhere. I hope your new home works out. Good Luck.

 

So are you porting your heads or having them done? If your having them done, whose doin it? I think the perf. rpm is an excellent choice particularly to build up some low end torque as automatics are bound to a little lower rpm's for a tad longer. I would reconsider on that carb though with all that power I would think that a 750 would be in order. Not that I'm really pushing it here but if you wanted to stay with edelbrock I have the one off of my motor for sale if you didnt want to buy a new one, I also have the tuning kit for it. No biggie just let me know.

Calvin, I am going to have SDPC port the heads. I just got into Georgia, pretty cool! Atlanta has a crap load of traffic! Did you get the pictures of my 84? Let me know. Oh, BTW a 90% efficient 350 at 6000RPM only needs approximately 560CFM of air. I only wish I was running 90% engine efficiency. It's really more like 80-85% efficiency. No one I know has a good reason for the 750 carbs on a 350 under 6000RPM. I want the smaller primaries for more low end and part throttle grunt especially with an automatic. Gotta go.

Yeah I got your pics, pretty sharp who did the decal, or is it painted? I've read those effeciency and cfm charts too, but I would be willing to bet a fair amount of money that it I put a 560cfm carb on my motor I would slow down considerably in the quarter, to push around 3500 lbs. down the track right at 117mph would be from 450-470hp, which needs more than 560cfm, and I shift just a hair beyond 6. Not only that but when carbs are flow rated it is without taking into account the fuel that is also taking up a considerable amount of sapce in the venturi's so there's not and actual 750 cfm flowing to the motor. Man I was praying that it would not rain today so I could run to the strip for some freezing cold times, but nope it had to drizzle all day. So whats got you in georgia?

------------------

Hey guys:

I've been reading your correspondence, and have to agree with Calvin on the carb sizing. A 600 cfm carb will choke any engines ability to make 450-470 HP. For example, assuming 470 HP, 0.5 brake specific fuel consumption (which is reasonable for an efficient street engine) and 13.0:1 air/fuel ratio, approximately 680 scfm is required to make the 470 HP (assuming I've done my math right). In my opinion, the 750 scfm carburetor would be perfect. I realize this equates to 111 percent volumetric efficiency on a 350 at 6000 rpm. But this is not unheard of with a Victor Junior intake (I've seen 115 percent on the engine dyno). just my $0.02

 

Well then, don't we have a little discussion going on!

The ZZ4 with Hot Cam is rated at 395HP. I run the quarter at 105MPH and for a 3400LB vehicle that is 313HP at the rear wheels according to Corral.net's calculator. Assuming a 20% power train loss that is 391.25HP at the crank! NOT BAD FOR A SINGLE 3" EXHAUST AND 600CFM CARB! I don't really know if my carb is hurting my engine or not but the correct horsepower is there. Not only that but an engine is an air pump and without supercharging or TUNED EQUAL LENGTH LONG TUBE HEADERS it is highly unlikely that our engines are reaching over 90% efficiency. As for the dyno I believe that 115% is possible but only with equipment our engines do not posess.

The emblem on my hood is air brushed on, it's under the clear coat! No stickers for me.

Calvin, I just got an engineering job in Georgia making plastic exterior components for the Big 3. I don't work on cars for a living any more I MAKE them.

Still here, just been tryin to locate myself a clutch and praying that it dosen't rain on sunday (track day). Man, somebody really did a sweet job with that graphic on your hood. So when do you plan on getting your heads ported?

I really appreciate the hood compliment! I really wanted to do something different. Get this, there is 31 COATS of paint on the faded checkerboard area. Just wish I had the money to finish the rest of the car. I REALLY would like to see your car run some weekend. Maybe a long road trip. Let me know what you think.

My god 31 coat I've honestly never heard of such, I guess thats what it takes to get it to look that good. As for the road trip, if your up for it, the more thirdgens at the track the better, as they are way under represented at the track I go to. Thats some very speedy wrench'n to get those heads off. I guess you have a back up vehicle during down time?

Yeah, I have my 91 Firebird God Bless it's 120 mile dying soul. I need to get a free weekend but I think that I would be willing to meet you half way in SC sometime. My Camaro will be down for probably a couple of months with waiting for the heads to be ported, finding time off work, cutting the AIR injetion tubes off my headers, on and on and on. That's what winter is for. If you don't mind me asking, what do you do for a living. Your car projects seem well financed and I would like to know your seceret. I need more car money! Thanks for your responses, it's nice talking with someone who has such a killer Camaro.

Well right now I'm working at a printing and sign buisness, only been full time for a year as I just graduated from UNCW.I have an application pending elseware that I am praying will come back positive. Most of my car projects are done by saving money or credit card (most of it).

You obviously work very hard. Good luck with your job search. Just packed my heads. What a pain in the rear. Even the aluminum heads weigh 40LBS! The darn things are going to cost me 100 dollars in shipping by the time the work is done.
