ditto.....

 

Kind of apples and oranges. AFR makes heads, AI and LE port them.Until AI and LE make their own castings......

AFR makes great heads for racing applications.But for street use, I'd send the stockers to AI.

 

I have a brand new set of Competition Ported AFR 1039s being installed on my car now.

 

oh boy...

 

Nothing against LE & AI but there is a whole world of very talented head porters out there.

 

Stop spreading that nonsense. LT1 heads are special that require someone to port hundreds of them to understand how to do it right.

 

Either can do well, pick your pony and ride it.

You want to go fast: do it.

 

OOOOPPS My bad.

 

what's impressive about an 11.9 at 120

 

I don't remember the last time I saw a full weight street car with a stock shortblock break 120mph. I also don't think 430rwhp with a stock intake manifold and waterpump is bad either.

 

What an under performing car... I mean most H/C/I 383's only manage to trap 120's Wasn't that run done with minimal suspension mods also? Damn, your car sucks...

 

nittos + setup to turn = 1.93 60' Still managed to mess up the 10 bolt with that awesome 60' too.

 

I've got a bud who runs all the best off the shelf stuff, AFR heads, Edlebrock intake, custom built headers and exhaust, Comp 292 camshaft, etc. I run whatever I can catch a deal on. I'll report back and let you know who runs faster.

LE and AI are both great porting companies, Me and my friends have used one or the other or both and have been satisfied with the results everytime. Both great companies.

I love how AFRs are a "gamble" when they have been proven time and time again on some crazy fast LTX *and* SBC cars.

The world is a bigger place then LS1Tech.com, some people need to get out more.

LE makes an awesome head for a DD on a budget, AI make a great package for a "hot" street/strip vehicle...but for all out performance I would put AFRs againts not only anyones ported stockers, but any 23* head period.

 

It is worth mentioning that you guys are comparing three different levels of product. AFR has a great product, obviously, and if it fits your application & you feel it is a value for the output, then it is worth consideration. They offer good machine work, and are so abundant as to essentially set the bar for the average good quality aftermarket head. Our niche, and what makes our product tend to outperform the mass produced heads is the level of our machine work. Manufacturing is always a compromise, and there are endless options for work from entry level to average/good. When we decided to move forward w/ dealing with the public, our primary focus was to set ourselves apart. That is precisely what we've done by being one of the only sources in the country where the average guy can buy a true professional racing level of machine work and attention to detail. It doesn't hurt that we can also bring our head and valve train experience from racing to bear on our programs for the public. Furthermore, being able to provide an entire system to meet specific goals, longevity requirements, output, etc. makes it much easier for the average guy to get where he wants to be, and increases the probability that his project will come together easily and reliably.

We haven't built any 383's lately that are currently being tested. Either way, comparing two different engines from different builders makes it tough to draw any sort of fruitful comparison.

There is no, and never has been a "battle." From the quality of work, to the dyno or stop watch, our products have never been comparable. That is certainly not to say that everyone wants or needs what we offer, however. Everyone's application, budget, goals, etc. vary, and fortunately there's someone to fill just about any demand from the market.

I thought he was referring to NA performance. Anyone can go fast if they force it in or bomb the heck out of the engine. What'd it take you, 6mos & maybe 20 passes to work your way into the 8's?

Stop, in today's "everyone is a beautiful and unique snowflake who deserves a trophy" world it isn't polite to rely on timers and other quantitative means of examination. Everyone's a winner as long as you had a good time.

Absolutely true! However, practically applied, they will still have a difficult time competing with the value and output from a specialist. Obviously that is due to the nuances of the LT setup, and scale of operation/focus. Tons of good options out there if guys are willing to invest the time in finding them & giving them a try.

Nuances, unique traits, etc. absolutely, but I must admit we're still working on the magic end. At this point I'm fairly certain our chicken bones & goat's blood are mismatched for our flow #'s.


Buy what you like, and if you care to try and improve your setup, we can always help do that. As long as we all have a good time.

Not anyone can do it. You know that. You can't just bolt on the parts and run the number. It takes time to work a combo out. It took me a while.

If my goal was n/a, my setup would put down much more power than my current nitrous engine that puts down right at 540rwhp 500rwtq n/a. It would involve AFR heads, lightweight rotating assy, some crazy valvetrain parts, different custom cam, special machining, polishing, oil control....etc. Not to mention the converter, gear ratio's, and suspension.

I would love to see you guys take a 14:1 396 LT1, do your magic on a set of AFR 227's or 235's, custom solid roller cam, Super Vic intake........etc. Spin it to 8k. Would be insane #'s . 600+rwhp n/a ?

 

do i fall into that fastest na lt1's list??? if so look what i got for heads and cam ......

 

i got one of them ^ lol

 

I see your track #'s but what is the hp and tq?

 

Oh yeah, it surely does once you get into significant power adder apps. Hope it was obvious I was just messing with you. There's an immense difference from the guy who runs a couple hundred horse worth of n2o or a 9lb blower kit vs. the real deal setups like you & the guys you're referring to. Much less the years of refinement and thousands of passes to make the car actually work.

If the little 215cc head we produce based on the 23deg TFS casting will make up to ~550-570rwhp NA on pump fuel, I am quite certain some of our racier 23deg heads would do it on an average short block. Especially if fuel type is open.
