o yea duh lol i justt seen 300 cfm and was like wow

 

I assume you're talking about the ones in the middle? They have a small channel machined on each side cuz when you put the gasket on there for mockup the plug cuts off half of the hole for coolant to pass thru. So my very perfectionist engine builder being teh observant chap that he is machines each side of the deck plug so the coolant flow won't be cut in half thru that plug...... it would be easier to describe once the gasket was on there in a picture...

 

Just a little heads up for ya, on racingjunk or ebay there are Alot of ALL-pro's floating around very reasonable.

I just picked up a set of All-pro 227's cnc'd to 255 that are rumored to flow 350+. I will know what they flow in a couple weeks. I got them with a set of Jesel J2k's for $2500 and the heads are fresh and the Jesels have 6 races on them. All new Del-west valves and Isky springs, Ti retainers ect. They are spread port exhast as well, 60/40 .085 dowel shift. They are going to AI fo a touch up and conversion and then getting bolted on

There was a big sprint car assioation that switched ther Spec heads from the ALL-pro's to a brodix. All the guys I talked to said the All-pro was a better head but the assioation was trying to slow things down a bit.

The guys I bought mine from were making 780 on alcohol with a very restrictive Kinsler injection set-up. They said with a carb type setup another 40-50hp would be very easy.

I too was looking at the RR215's from AFR and almost got them, but the wait was rediculous and I thought about getting them and having them ported by someone but everyone I talked to was leary of doing it due to casting problems they had seen with AFR in the past. The new eliminators are really what I wanted but I didn't want to wait 5 years to get them

Just an option if used parts happen to be in your radar scope. I have 2 kids so I have to budget my go fast

 

yeah another vote for racingjunk dot com... that place is the ****.....

i'm happy with what my 227's flowed and they'll be more than enuff to hopefully run 9's NA and 8's on the bottle....

330 cfm on the intake at .700 i'll take anyday...

 

Not trying to knock the AFR stuff at all, if you get the set from them. If you guy an as cast set and are trying to get them from as cast to ported I would stay clear though.

 

I got my set from them with the competition CNC port and the upgraded springs, retainers, etc.... basically the best setup you can get from them directly.... They probably would flow in the 310-315 range at .650.... However my guy building my motor wanted to spend more money going back thru them by hand as there is about 10 cfm in the heads from where the CNC grinder meets from the top and bottom and leaves a ridge in the intake port. Plus the CNC machine leaves a tooling on the port taht can be polished away with a good hand porter.....

my ports now look absolutely beautiful and they are in the 330 range...

 

Out of the Box AFR's for t3h win!

Tony.

 

enough nitrous will fix anything

 

WERD....... 1000 dollars more in head work or $2.55 for bigger jets...... hmmmmmmmm.....

 

Now You guys would NEVER accuse Me of that

Then again I am still using stock modified castings

I am back to the waiting stage. Going to add a second stage and the car is stripped waiting to go in for the new CM 10 point and NHRA cert

 

I hit the nitrous on the dyno on this engine for the 1st time yesterday! Look out guys! It loves the spray!

back on topic:

anyone gonna try the new AFR eliminator heads? I think I might.

 

There is a local guy putting some eliminator heads on his 383. It'll be a turd

Tony.

 

Does he have them in hand yet??

Not the LT1 eliminators I take it?

 

this thread should a sticky, there is alot of information, keep talking guys.

 

+1 on the sticky..... i'm down....

Yeah I thought eliminators were still months out....

Tony I am working a deal with an individual at AFR on doing a comparo on before and after dyno #'s and track times with no other changes other than swapping from old school 227's to the eliminators.....

That's if my pig ever stops punishing these jackstands...

 

That would be baller!


From what I understand the 180cc/195cc/210cc eliminator heads are in production, the 227s are still being R&D.

Tony.

 

I hear AFRs are hype Nah, I want to see what these new AFRs and the new Trickflows do, be cool to see, maybe make it even easier to break the 500rwhp barrier with a street hyd roller cam and LT1 intake.

 

there's a couple of links on corvetteforum.com about the new eleminator heads. One of the guys on there got a set of the comp ported 195's (I believe they are sbc) but none the less look pretty nasty. Here's the link...

dude that setup looks awesome

 

thanks man.... it's farther along now. actually days from completion.... gonna be an animal that's fo sure..... I gotta do something to take it to those Texas Boys!!!!1

It looks more like this now, only the heads are actually on there with studs.... all that's left is the intake/throttle body and putting the crank trigger and distributor on there and phasing all the ignition stuff..... i should be up and running soon.
