i got all my stuff from TPIS. i got the big mouth intake, large tube runners and 58mm t.b. after i got them i opened them up alot more ( read as ported them more ) . love them to death. if i had to do it again i would get TPIS and not the edelbrock or who ever the other company is that makes tpi intakes.

everyone (except above) seems to love the SLP siamese runners and for the cost they are great. For the price it seems everyone loves to port thier own upper, get some SLP runners and a edelbrock lower.
But if they are still around or you can find some the setup from Arizona Speed and Marine (ASM) used to be the only game in town. Thier runners were HUGE and thier lower was huge and was similar to the TPIS bigmouth and Accel TPI lower.

If you like the TPIS Large tube runners its alittle cheaper to goto Arizona speep and Marine and get theres. They are the exact same runners as the TPIS ones, TPIS gets theres from AS&M then sells them afters a mark up.

As far as the base. TPIS has there base made by edelbrock. ITs the same base as the edelbrock high-flo. TPIS just changed the name and port matches it.

Personally.. i'd say the Accel/lingenfelter large tube Iron cast runners. I have a set, big improvement.

AS&M runners seem to be the best over the whole RPM range, and SLP seems to flow the most, although they sacrifice some low-end.

....I haven't tested them, but there's that graph floatin' around here somewhere...

well, thanx guys. u mind posting some prices and part numbers?? i have a decently built 305, and i want some power from 4000-5500, where the stock stuff lacks.

Could always use a LT1intake (www.lt1intake.com). I know its a very good upgrade. Here are some charts for ya:

pasky, already tried that route. too much for my 305 on ported stock heads. lose a ton of torque, and don't gain enough hp in return. i have mine for sale though..... has everything needed

AS&M SS runners. 1.75" OD. 1.66" ID







I got mine for a steal @ $300. They are brand spankin' new, but no box. Oh well, never was much for packaging anyways. Perfect finish inside and out, no dings/dents. Light as hell too. They dont' weigh anything.

Cost no object, these are the best runners to get that are compatable with the stock design bases.

The best TPI system out there is the First Injection system. www.firstinjections.com. But its not compatable with any other TPI parts. Its all or nothing with that setup.

B4Ctom1

Yeah, I remember that electromotive stuff, now they are selling just the intake without the electromotive system?

FruityOne

I have talked to ken through emails and thats what I've come to understand.

You can get the Upper Plenum, runners, Fuel rails, and base for $900 or something like that. No electronics included. I'm not sure if the stock Fuel injectors will work with the rails or base though.

I don't have the money to get one, otherwise I would for a big inch SBC. But I don't have the money for that either.

So my AS&M setup will do just fine for now.

Personally.. I like my Lingenfelter / Accel TPI runners. There are various threads in the archives with info on the various flow rates etc.

You pay your money and you take your choice!

Personally I'm going to go with TPIS. I recently dealt with them and enjoyed the transaction. Their runners are the same price as AS&M's, and they are not cast, which is a good thing.

blackztpi

honestly, i hate everything about TPIS. they have snobby customer service, and they overprice everything so much. look at the prices on the headers!!!!!!!! like 100 bucks more than anybody else. I'd never buy anything, except for their tpi dress up button kit with throttle body plate lol

FruityOne

AS&M's runners are made of extruded aluminium. Same as the TPIS (exactly the same actually).

Out of the box they are probably the CLEANEST, and best flowing runners you can buy. And the Semi-siamsed runners are incredible.

Here's a high res picture of the runners, I posted the smaller version above in my first post.

I did alot of research on long tube runners about a year ago. I learned that the AS&M(same as the TPIS) flow the best I was going to get them but I got a good deal in a SuperRam on Ebay and didnt go with a long tube runner set up. I have heard alot of people complaining about the SLP runners. Saying that they looked liked they needed more machining and they had fitment issues. The pics of those AS&M runners above look awesome. I'd go with them if I were you

u guys have a website for ASM? what do u think aobut edelbrock's?

Thats not an LTR setup.

He asked for the best TPI runners, and the HSR doens't get included in that list cause its not LTR.

I'm not bashing the HSR, but it really doesn't start to show gains untill 4,600rpm or so, and before that the TPI setup will make more power.

I will go HSR or LT1 eventually, but for now I like the look of my TPI setup, and I love its performance for the street.

Another vote for TPIS/ASM. After comparing ACCEL, Eldebrock, SLP, the TPIS/ASM are superior in fit, finish and flow compared to the cast runners.
As a side note I have made many purchases from TPIS in the past. This was when they where one of the very first offering TPI upgrades. They were courteous and informative. The products, even though they were on the pricey side, were quality items and arrived on time. The only problem I had was with a re-bored throttle body that wore and the throttle blades stuck and caused a high idle. This was when the TB was almost 3 years old and out of warranty. When I mentioned this to them while ordering another item, they told me send it back and they would take care of it. I have to give credit were credit is due.

blackztpi

sounds good, but they are like 475 bucks!!!!!! I'm hearing the edelbrock base is the best? and again, HSR and LT1 covnerted are cool, but i have a 305, and i wouldn't get enough high rpm power with my slightly uprgraded LB9 heads, and I'd lose too much torque in return. on the stock TPI system, It'll make power to about 4750rpm, and shift at around 5200. mototr isn't stock, but i think I'd be fine getting large tube runners and baseplate to help raise that powerband just enough to comfort my hsift point. what do u guys think, about 10-15rwhp gain? GMHTP got 5rwhp from slp runners on stock baseplate with stock cam and heads. i think i can pull 15rwhp with runners/base????

You will be hard pressed to find the edelbrocks. I held out for many months (6 I believe) waiting on summit to get more, and even according to edelbrock, they are on back order.

I went with the accell/lingenfelters. This is how they look in my engine bay.

I'd have to go with the TPIS I have never had a problem dealing with them. They help me get the right cam to go with their complete add on kit for my 400ci 425hp to match the Injection kit and I ended up picking up around 50 more horses and something I don't have to stop at every gas staion. I grant you that they aren't for the guy with a tight budget I'm into mine injection alone around $5000.

I got the TPIS large tube runners and love them and they fit perfect, they are by far the best. They are exstrude honed and not cast like most. I got many things from TPIS had no problems.

I had Accels LT runners and they where bulky and did not seat well on Plenum plus the inlets and outlets where stock size diameter so they need ported especially if you got a high flow base.

mykxt202

TPIS even matched my intake to the high flow heads I'm running all it did was make a template and sent it to them. I checked it when I got it with a copy template I had made and they were right on

Theirs nothing like getting rid of the carb and going with one of these systems. The car is now a 100% better and more reliable on the track. No more screwing with the carb everytime the weather changes and were I live the weather changes every 2-3 hrs

I dont see anything about semi-siamsed runners anywhere on AS&M's site there. They not makin em anymore?

They make them. When you're ready to order, give them a call... $475

FruityOne

Thunder Racing carries them.

Very shortly I might have mine up for sale. I never even got around to putting them on the car. I paid $300, so will want $300 as I'm going to an LT1 style intake.

Just have to get the cash together to buy a LT1 intake and convert it.

Red Devil

AS&M LTR's and Big Mouth base. I'm lazy and I've liked 'em since they each came out.

ThirdGenFire

What about the LPE Base? I hear that it is a very good base. Flows very good.

How do these aftermarket runner hold upto denting as opposed to the stock tin tubes?? I was playing around with my car last weekend and gently tapped the runner a few times and there was a small dent left. I knew they were thin but damn its pathetic.

Id hate to put out all that cash and accidentally dent them, anyone know??

FruityOne

Very thin, my AS&M Runners weigh almost nothing. They weigh less than a 12oz can of pop I think.

BTW, the runners have been promised to a friend as he's going to do some work for me. But I won't be letting them go for another month or two at the least.

All my leads for an LT1 intake fell through. Grrr....

Well if the deal falls through with your friend, Ive got $300 cash with your name on it. rpperformance@comcast.net

FruityOne

Well, just thought I'd update this thread. Give out some info to anyone who runs accross this and emails me.

The runners are no longer for sale. Mainly because instead of an LT1 intake, I found a LT1 short block for FREE!!!!! Thats right, FREE!!! I decided that I would eventuall build a 383 or 396 LT1 stroker for my car and build up a motor over the next few years.\

Now, however I haven't been able to clean up my car yet, but here is a picture of the AS&M SS Runners on a car. NO dyno's or anything like that. Not that they would be valid anyways as NOTHING about the engine is original.
