A little backround for everyone....

I'm mating a reverse split TR 230/224 cam whose actual cam specs are:

230.8/224.2 .576/.563 110.8

The cam is going to be paired with a set of TEA stage 2 5.3L truck heads with 2.02/1.55 Ferrea Valves, double springs, and titanium retainers.

The heads have the following flow #'s....

Lift Intake Exhaust

.100 72.2 55.0
.200 141.6 105.2
.300 205.6 151.5
.400 254.6 193.4
.500 290.1 231.0
.550 300.4 247.2
.600 306.2 260.4

TEA told me this set of 5.3 Heads has been their best set of heads flow-wise to date. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> They've only been able to get 303 intake flow at .600 and a little under 300 at .550 in the past. <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />

Hopefully this combo will go well.....I know TEA's process focus on mid lift #'s and velocity, not peak flow #'s which made me a bit skeptical.

Opinions on flow #'s guys??? I know every flow bench is different......

Nice numbers <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Sounds like a good combo.

Those exhaust numbers are with a stack though. Subtract 20-40cfm from the exhaust numbers depending on what sort of stack they used.
cheers,
Chris

I know you dynoed w/ stock heads...but I'm curious to see that the SAM heads did for ya!

Actually, I've always had SAM heads. Dynoed 414 rwhp through an A4 locked up. Only been to the track once. Ran 11.70 at 116 mph which was really good for 3 reasons.

1. My race weight was over 3,700 lbs (heavy convertible)
2. The weather was hot and muggy.
3. My 60' time was 1.68 which was only accomplished by going out 1/2 throttle (dang Nittos). Had I run ET Streets, my 60' times would have been closer to 1.55 and the ETs would have been in the 11.50s. I basically have an 11.20 car in cool weather. Take off 500 lbs (to get it closer to the REALLY fast guys) and you can see I have the power potential of 10s N/A.

But for me, I'd just rather keep my convertible very pimp (and heavy) and just spray the hell out of it to get my 10 sec. time slips, haha. <img border="0" alt="[pimp]" title="" src="graemlins/gr_pimp.gif" />

Yeahh. For the convertable guys. I have a 2000 SS convertable. With a 1/2 tank of gas, a full bottle, me and a heavy *** 9" with 35 spline axles and aluminum center section it weighs about 3950. Best e.t. 11.34 @117 mph 1.60 in 60ft.

my tea heads flowed 318 @ .585 lift and 312@.550
the flow numbers are good but not the best they have ever done <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

TEA site on corvette forum.those numbers are from 5.3 heads also.

BTW Not trying to flame I think your combo is gonna run very good.

2.02 /1.57 Ferrea Valves
this was with my 5.3 heads.I now currently am running 5.7 heads.
But someday I want to try a set of 6.0l heads.Like I said in another post to you the 6.0 heads have a killer mid lift compared 5.3 and 5.7 heads. I am sure some of it is due to the larger chamber, but also I think the better short turn on the 6.0l head helps alot.

Your intake numbers are the about the same as my TEA 5.3's but you got me a little on the exhaust. Mine peaked at 249 at .600. They didn't flow that well on my local bench though. But as good or better than any I've seen out there. I haven't installed them yet but I will soon. I'm still waiting on LS1 edit.My cam choice was 230-230, .591 lift on a 112 with +4. Thats pretty close also. Post your #'s when you get it all together! It should be a monster. I bet your around 11.4-1 also. Good luck! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

I can not say enough good things about TEA. Those 5.3L heads are awesome units and those numbers are even better.

Belive me port velocity and mid lift numbers are what makes you win in the real world not huge CFM numbers. I have a very big feeling that in the future people will look more at the velocity and mid lift numbers when they are head shopping.

It's just a hunch.

TEA gave me a price breakdown on the phone for work I wanted done to a set of 5.7 heads.

I havent purchased anything, but the prices I was quoted are great in my opinion... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I can give you some info as to what they quoted me if you send me an e-mail. They broke down the prices individually.

Ron,

I just got off the phone with TEA decided to have them put a better exhaust valve on there, so they are putting a dished exhaust valve on there that will flow about 5-10cfm better across the board on the exhaust side.

The downside is that it drops my compression down to 10.6:1 or so, but they will do some slight milling to get it back up to 10.8:1

I told them I don't want any more than 10.8:1 because of our crappy 91 octane. If we had better gas I'd run 11.5:1 or so.

Their price for a stage 2 heads with double valve springs and titanium retainers ready to bolt on cost as much as most companies' stage I heads w/ no options. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Nice numbers. Get those things on. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I have spoken to Brent at TEA on the phone and their pricing is great. Been waiting for a few people to post results because TEA's 5.3 heads are looking real good. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> Flow numbers for over .600 lift don't mean anything to me because I'm never going to run that big of a cam. TEA's numbers from .400-.600 lift look real good for the money. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

OK, I have a revised flow sheet for the exhaust side of the heads....I found out Ferrea exhaust valves don't flow as well mid-lift compared to another company's valve, so I had them swap the Ferrea Exhaust Valve off, in favor of a dished valve. The negative is that the dish valve dropped my compression a few tenths, and I had them mill the heads to .010 to bring it back up to 10.8:1.
