What heads did you pick up?

The AFR 227 headed car I am refering too here has nothing to do with AI.

Are you trying to say all the 9 second cars you listed are street cars??? Never been on a trailer??

Far as the accustion of being on anyone's payroll, I assure you I am getting just one W2 this year. Look at the results without your blind dislike of me, A pump gas NA 383 runs faster than a larger engine with a 250 shot you sighted as a good example. You are not being objective.

 

I am being very objective. I said there are many ways to go fast. I said that AFR makes some excellent stuff and so does AI. More to going fast than having the most hp. Stick around a dragstrip long enough and you'll know that. Rick Abares car is set up VERY well. It's much easier to set up an N/A car than one that is getting a 250 hit.

 

Define poor. Every set ive ever flowed did well and made power. They have got prolly one of the best flowing exhaust ports out there for a 23 degree head. And my hats off to them for actually running a 8mm valvestem. Less valve weight is always good for some power upstairs.

 

We flowed 2 sets of 190's. They ranged from 233-240 cfm even though they were advertised at 260+. One set took some significant porting from GTP to get even advertised numbers. The 210+ cc heads are a different story. Every set I've witnessed, including 2 sets of my own, did within about 5 cfm of advertised.

 

Wow that is pretty poor. The last set i flowed were some 195s and they went like 270 at .600 on int and 226 at .600 on exh. The only thing i noticed is they backed up on me when i went to .700. But it was a streetcar, so the cam wasnt much over .550 lift. They flowed pretty good in the lowlifts, and had a killer exh port. Were you flowing them with a radius on the int entry?

 

Yep. FYI They were all flowed at Thunder.

Guess you are referring to me? Not noted is that run was with a busted tranny with no 2nd gear and no trans-brake. Handicapped it still ran mid 9's. Try another example Duane.

 

[QUOTE=Tony Shepherd;10924795]He's too busy sucking off AI guys, or browsing the Taxi/Caprice boards right now to look for a different example.

I'll say it again for the AI guys that work there. I will NEVER buy your stuff simply because that 96capricefggt promotes you guys so much and bashes everything else. You guys need better spokespeople. You should tell him thanks but no thanks.

 

This is the problem with the Internet....

You guys are discussing cylinder heads we haven't made in close to three years now. Whether there were reasons at the time they were a little soft then isnt even worth getting into.

As most of you know we have completely redesigned our SBC program naming the new 23' product our Eliminator program. It was a complete clean sheet of paper redesign including all new aerospace quality castings, all new extremely efficient port and combustion chamber designs, lighter weight 8mm beadlock valves and premium small diamter lightweight springs....I can go on and on with other small details. The new Eliminators have ZERO in common with what it seems most of the negative commentary in this thread is hanging their hat on. They represent the most efficient 23' port designs in any of their respective class with our smaller street heads outflowing some of our competitors race heads and our race heads in a league of their own when considering affordable out of the box 23' heads (not one off extremely cost prohibitive custom heads that you can spend thousands additional and possibly still not match what we have achieved after investing more hours than I care to remember).

Our new Eliminator "street" version 195 at less than $1500 out the door smokes our former ($2000+) Comp 195 and does it admirably....how about 280+ CFM at, or earlier than .550 lift. The new Eliminator 195 Comp package (at a legit 196 cc pour volume) is arguably the most efficient street head on the planet (bolt-on 23' head) nailing 300 CFM's by .600 lift or slightly sooner. I challenge any of you questioning the ability of our product to find something comparable at that finished port volume. Our new 227 is knocking down over 320 CFM by .650 lift (the new Elim's flow big air and do it at lift points most enthusiast can actually use which adds even more to their effectiveness). We are about to launch our new 235 cc 23' Eliminator head and I will put this head up against anything in a non raised runner 23' bolt on piece. It has a 1206 entrance just like our 227 and has all the same valve and stud locations. The new 235 will flow in the mid 330's at .700 lift (310 as early as .500!!) and flow over 340 CFM if you have enough valvetrain to vault the valve over .800. With some of the real aggressive cams out there and the higher rocker ratio shaft systems, that type of lift is within reach if your building a take no prisoners race car and need to stay in a 23' head configuration.

I encourage all of you to spend more time researching the new Eliminators and the results of the customers that have been using them....you will be hardpressed to find ANY negative comments from those actually running them.

Here is an independent test that was done awhile back when we first launched the product. We weren't involved at all.....just privied to the dyno results. It shows how effective our new Eliminator 195's are versus our former product which was usually at the top of the heap in many independent back to back comparisons (of us versus our competitors). It shows just how much the new Eliminators have raised the bar....

Here is what David Vizard had to say about our new 195 street head....this guy is an expert in the field and has been writing books and building engines longer than some of you reading this have been alive...

http://www.gofastnews.com/board/tech...er-masses.html

I could add more but this is certainly some of the larger points I needed to get off my chest and present to you guys.

DO the research guys....unfortunately the Internet is filled with alot of questionable information.....some of which has hidden agenda's as well.....thats just the nature of the beast.

Also, feel free to contact me directly if I can be of some assistance regarding any of our product.

PS....Some of you are "cough cough" discussing older AFR 185 SBC heads....a product that to my knowledge we never even made (only 180, 190, 195, etc.). The only 185 product is a Ford offering AFR launched in the late 90's and has also recently revamped as well.

 

^^Take that 96capricemgr, lol!

 

i may buy a set of afr heads in the future,but im still trying to figure out why lt1 heads are 500 bucks more than the sbc head

 

Does all this eliminator redesigns apply to the lt1 heads? On your site it says eliminator series heads under sbc heads but in the lt1 section it does not mention eliminator once.

 

Here is a link to look at, http://www.airflowresearch.com/195sbc_lt4.php , read the top of the description for the cylinder head selected. (AFR 195cc SBC LT4 Eliminator Street Cylinder Head)

 

But not the 210's or 227's?

 

They just haven't updated their web site or it could have been an oversite when they updated the flow numbers. The flow numbers are for the newer Eliminator series. Also remember that you will lose a little bit of flow when you put these on a 4.0xx" bore vs. the 4.125" as tested. I would PM Tony and see if he has this data available for you.

 

Thank you for clearing that up for me.

 

Guys,

Every SBC head we currently produce is technically part of the new completely redesigned program.

Essentially, if your buying new AFR SBC heads now (or in the last 18 months), you are getting (or have) our new Eliminator product....its that simple.

If you bought our product a couple of years ago (or even second hand recently) and you aren't sure, just see if the casting has an "A" on the exhaust side face of the casting or an "AFR".....the newer Eliminator heads have the latter (the AFR logo). Also, another quick tell is to measure the valve stems.....if its approximately 5/16 diameter (8 mm) its the new heads.....an 11/32 stem (.341 or so) would mean you have our previous generation.

Hope this helps....

-Tony

 

Tony do you have any flow figure's for your 210 & 227 LT1/LT4 cylinder heads on say a 4.060" bore?
