no. Push rods operate in compression, and therefor are very strong. use some good quality chromoly units.. and no worries

*edit*

DOH! I know what I meant

 

so how come arao heads arent as bolt-on as they say they are? what exactly is the problem with them?

 

Thanks Jordon!

And Nitromethane this is a difrent thread that answers your question-

If the pushrods are opening 2 valves they definitely need to be stronger. 3/8 with .080 wall should be at least 50% stiffer/stronger than 5/16 with .065 wall.


oops! You meant "compression" right? Otherwise we'd be calling them pullrods.

Well ive always wanted to try to "Split" and thread (an option for us mods) and never had an operotunity to do so. So i think ill use it on this thread and split out the sb2.2 stuff into a new thread...

of i go Weeeeeeee

 

Often thought you might have a split personality...

Good idea.

 

straight off their site. you can use any intake you want. and hooker makes the 7 bolt flange for the headers. granted yes having 2" primaries would be nice. no special pistons needed up to 10.5:1. if i haver $6000 to buy them i would. but hey i'm broke just like the rest of you guys.

Use standard intake manifolds, cams, pistons to 10.5:1, and Hooker or Stahl 7 bolt pattern exhaust (Chevy) or Motor ‘n’ Sports (Ford) header flanges. Accessory holes in ends of heads.
Kits include Pr. of valve covers, Pr. of heads completely assembled, Pr. of head gaskets, notched for pushrod clearance (Chevy only), Set of 16 pushrods (Ford and Chevy), Set of head bolts (Chevy only).

 

What they fail to highlight on their website from the text you quoted is that since the heads come in different sizes, one intake isn't necessarily going to work for all three series of heads. I've got the BIII series and although he says a 1209 gasket will work along with the corresponding intake, it would be a major restriction; and the gasket still needs to be opened up as well. When you get a chance, take some measuring equipment of your choice and measure the ports on an LT1/4 manifold.... Now stretch out your measurement to measure 2.5" tall x 1.5" wide. Thats the size of my ports.....

 

that's pretty big, my T1 heads are like 2.19 or 2.2X i think by 1.5

 

I think i'm in love-

Don't worry Ken, they aren't real! LOL. Seriously, Bobby, do you REALLY have a set of those heads? I wonder if Russ Arao really even made a single set sometimes. I've seen the pics of UnstableBob, and I think its all a photochop! My friend and I have tried to get a set of the B3s for a SBF for 2 and a half years! Everytime we call, the reply is, "We aren't taking orders right now, as we are ramping up some new machinery, and it will be about 6 months." LOL 6 months, every time we call. I think BIG Show and UB are the only 2 people that have a set of them at ALL. Bobby, didn't yours run, or aren't they running right now on a carbed app? If so, did they include the spark plug wires? If not, what kind of wire did you use, as they are deep in the valve cover, right? I've talked to ONE person that had a set of them for a SBF and he sold them after waiting a year and half for Russ to get him the wires, which he never did. Oh well, I can dream. One day, I'll win the lottery and MAKE Russ make me a set!

 

100% unaltered photos, except for cropping and brightness/contrast adjustment.....

Guaranteed!

Have you seen the one of UB his-self holding one of the valve covers......

 

I bet its just UB holding an overly large can of starkist, and the cover was shoped in.

 

Hey that's cool, 440 cfm intake, 335 cfm exhaust. Not lacking in flow are they.

I personally would save myself alot of headache and do a sb2.2, pro action 12 or 14* conversion. At least there are cast intakes for those heads and they can flow well over 420 cfm with 300+ cc ports.
I don't doubt that some racer has put an Arao engine together.... I'll be damned if I've heard of one winning all the gold though. Who knows.

-Mindgame

 

I have a picture of one of my heads on the opening page of my site. I took the heads to Greg Goode and watched him flow them myself on his correctly calibrated flowbench. I also proceeded to watch his jaw hit the floor which I have never seen happen

I haven't had a chance to run the heads. I was building a race only application and as usual decided to change my mind and go a different direction. I mean, what fun is it to have something that you can only enjoy a quarter mile at a time? In the process I also jumped into a major purchase that kinda put all things on the backburner so thats been the major hold up.

To date we have all the pieces including the offset lifters for the longblock. ZTurbo is taking care of the intake side of things and we're hoping to have things together for the Thunder Southern Shootout, although I may not bring the car cause the only class it looks like I can run is pro outlaw which would be a complete waste of time and cash. So I'll probably just go to watch. Depending on where the car is at, the lil' parts getter (my S10) may get the nod for the trip to Louisana.

Russ Arao has been a complete waste of time to work with or even depend on. He has been promising me an intake now for over a year and you see I've given up on him. He won't answer the phone and won't return messages. Rest asure this motor will make some serious waves and I can guarantee you now I will make sure he doesn't get too many accolades because of the lack of customer service he has provided. As we all know, customer service is everthing in this buisness.

I know everyone is patiently waiting to see if the hype is worth it and hopefully soon we will see. I'm just as anxious as everyone but I'm also a budget racer for life so things have to happen in time.
