Been away from TGO for a while. I thought I'd post these and say hi to you guys. Although I waited a while for the product, I have to say, the product is excellent:



I look forward to parking the IROC soon and pulling my current polished TPI and putting it in my '54, and adding the 58mm TB, new runners, and port matched plenum to the IROC. When my '54 is done, my lovely wife green lighted my IROC project.(see my vB garage) At that time I'll add a better intake with many more alum parts. But for now, I'm happy to have a Harley to ride to work this summer. The 54 should be done before it gets to cold to ride.

 

How long did you wait and what did you pay Daniel?

I didn't see your name in the big group purchase for them that has been going on since last fall.

I've been waiting for my set since January I think, should get them within a month or so.

Better pics for those who haven't seen:

They definitely are MUCH bigger, MUCH lighter and the welds are beautiful.
I can't wait till my set comes in.

 

reminds me of my prominator group buy took a year but all worth the wait

 

I wasn't in the GP. I paid $451.04. I ordered them back in March. I hope this doesnt make anyone angry. Sorry my pics aren't that good.

 

Did you order them straight from AZS&M?

Considering I only paid $350 in the GP, I don't mind that I've had to wait so long.

 

How many more ponies are those good for? At $450+ or $350 and a long wait they'd better be sweet.

They sure look more "tubular"...

As much as I like factory TPI and have ran with it / broke it / fixed it, I liked it even more when it was gone.

 

I'll never know how many they will give me by themselves. I won't see any change in hp with the factory intake. When the '54 is complete, I'll start on the IROC. (Motor/man.trans./carbon fiber shaft/tubular front/all alum parts.)

 

i <3 tpi

these runners just glorify it even more, haha.

the edelbrocks i have now just don't retain that lovely long tube design.

 

Time was more important to me as it was holding me up with my '54. I called Ben @ AZ. S&M and ordered them directly from him/them.

 

Very nice Daniel. Can't wait to see some kind of finished TPI engine!

 

I'll post the '54's finished motor/enginebay pic here as it will be 3rd gen related. When I start the IROC, I'll start a new thread for it as well.

 

I had a set of the AS&M SS runners on my 89 GTA. VERY lightweight runners, and very easy to dent too. They look sweet in person, and the performance is very nice too.

Thanks to RUQWIK and Camaero, I was able to get the IROC back on the road. Those of you still waiting on the AZ. S&M runners make sure you remember that the flange is different than the factory runners have and you'll need to get the correct size torx bolts for them. I forgot the lower ones and had air leaks. RUQWIK came over and brought it to my attention. Thanks guys for the moral support. I'll get some pics up tommoro.

 

What's this about different torx sizes? Bastards should have included a full bolt set with the runners....

 

Simple solution, go to the hardware store and pickup steel spacers, or shorter lower torx bolts. The spacers were easier for. I don't remember the exact size I needed, but I know I found them on www.mcmastercarr.com

*edit: which apparently doesn't work.

click the washers link under the Fasteners heading and choose female unthreaded.

 

I'm the last on the list to receive mine, but I'm not in any hurry.

Thanks for the tips!

 

My set was worth 4 HP and 10 TQ at peak at the rear wheels, on my old engine combo (L98 heads, ZZ4 cam). I was still using them when I posted the power numbers, and went the ET in my sig (L98 heads, LT4 HOT cam).

If you have the time and the ability, grind away on the divider between the runners and make them semi-siamesed for more power.

 

So now for the important question, did you feel a big difference Daniel?

 

Good to know Kevin, thanks for that.

Since I have alum heads & the ZZ4, not to mention a blower, I'd hope to see some gain over my Edelbrock runner set.

 

Are they any better than a fully ported Edelbrock combo? I always wondered what power would be attainable with a Edelbrock runner and base combo that was extrude honed?

 

Edelbrock runners and base that have been extrude honed are comparable to AS&M runners. A car in SoCal with that exact same combo dynoed around 270 RWHP thru an automatic, L98 heads, and ZZ9 camshaft.

 

Hard to tell. She runs way lean at low RPM and throws codes. I need to data log it with Camaero soon and burn a new chip. I got the IAC and TPS set thanks to him. At 3500+ she runs good though(air/fuel mix). Keep in mind I still have the stock base intake and a very tired L98 that's completely stock and burns/leaks oil. When I finish my '54 Chevy pick up, I may get to start my project IROC(See vB garage for dreams). The only reason I chose to get the 58mm TB and AZ. S&M runners now is I decided to run the polished intake from my '88 on the '54 and take the cast stock plenum I nabbed from an '87 305 Firebird. I know eventually I will need more air to feed the 383. I also like the stock satin look of the new TB and runners with the '87 plenum. Here's a few shots(be nice, she's filthy):

 

[QUOTE=If you have the time and the ability, grind away on the divider between the runners and make them semi-siamesed for more power.[/QUOTE]
I'd like to see pics if you have any. I did some more on the plenum. When the TB is open there's a straight shot to the plenum. Are you talking about semi-siamesing the runners or the plenum ports on the side. I'd hate to have vacuum leaks. Please post pics if you have any. Thanks, Daniel U BTW, with the stock base being used witht the 58mm TB and new runners, she's lean at lower RPM's. Will this be fixed with a little PROM work? Thanks Kevin, Daniel U

 

Wasn't done when I took that pic, didn't have any properly sized gaskets so I made a paper template and would just grind a little, compare, use a little marker, grind some more. Cleaned it up much more too.

Also ground down the EGR wall at the front of my plenum too.

 

Siamesing the plenum like that doesnt do a thing. I am talking about grinding away the divider between the runners where they bolt to the plenum. Its joined together right there so you can safely remove a bit of material.

 

It does if you already have the AS&M semi-siamesed runners.

http://student.dpg.devry.edu/~d00712...s/DCP_0430.jpg

gives the effect of a larger plenum and shorter runners. Not much but the tests showed a nice gain in the upper end back in the day.

 

Has anyone here on the West coast had there parts extrude honed?
www.gethoned.com
I was thinking about it, but it seems kinda $teep. I'm curious if it will help when I go to the 383? I plan on having it balanced well internally/externally. I also plan on using lightwieght parts. I want it to breath well at higher RPM's. Any input is appreciated.

 

Can't extrude hone these runners. The aluminum is PAPER thin, literally. No way to port the AS&M runners at all, you can port the flanges a bit, but thats it.

 

Yeah, I suppose I should've been more clear on my question. I was more curious in the plenum and base intake. I plan on getting an Edlebrock/TPIS/whatever base, but wanted to get it worked on. I thought if I heard something positive from someone local and maybe some dyno #'s to back it up I may pay the extra dough. I also want my heads done too! This is all stuff way in the future as all my $ is going to my '54. Just doing research for the future.

 

A local person had their Edelbrock intake and runners extrude honed. My ported Edelbrock intake flowed about 250 and theirs flowed about 260. Its worth it if you're going to every last little bit but I think you can get more gains by porting the intake manifold yourself. The pinch area is where the injectors are, and gasket match everything else.

 

Yeah, TPI has a little trouble with HP, so every last bit of porting is worth it if you can swing the time/effort, or cash to have it done.

The AS&M runners are bare none the best factory compatible replacements, nothing comes close in terms of flow. Port the plenum to match the runners, and port the base. The aftermarket bases should have more flow stock, and better potential with porting.

 

Camaero and I did a little data logging the other day on both our IROCs and were able to make some changes in my spark and air fuel mixture and various speeds and RPM's with his new toy from Moates. Although I'm throwing a MAT sensor code when I'm warm at idle, the Vacuum leaks seem to be corrected and the L98 seems to be running close to 128 BLM's at idle/freeway/and in town driving. My throttle cable seems to be sticking a little too. Do they need lube over the years? If so, what type and how would I do it? Thanks, Daniel U

 

The throttle cable is fine. I did lube the interior pedal linkage. I think I need to rewind the spring on my TB. It returns fine when I'm @ WOT, but at cruise, when I let off the gas, it seems to stick open partially.

 

Now that it's dialed in on the ECM, I wouldn't say that I feel a "big" difference, but the fact that I was running leaner then before tells me that despite the fact I'm still running the restrictive stock base intake, I'm still getting more air through the motor with the bigger 58mm TB, AZ. S&M runners and port matched plenum. Not sure how that works exactly, but I like it? I think when the time comes for the 383, I'll get the alum. heads, intake and plenum extrude honed. Thanks Kevin, Daniel U
