I am planning on going with both later on, but I want to know which will help my motor the most. I know the factory intake is very restrictive, and also the heads. Which would make more hp

the stealth ram with stock heads, stock bottom end, and headers.
or factor tpi system with the trick flow heads with headers.

Keep in mind I will be running 3.73's so I need a few more rpm's.

thanks.

 

hmm.. Well i would get the heads first, because you'll pick up a lower ET than if you just switch to stealth ram. AND the heads are more expensive, so after you buy the heads, the intake will seem like pennies!. BUT you would run the risk of Holley raising their prices....

 

I'd just like to throw a vote in against Trick Flow period.


How come you decided on those heads?

 

If this gets into another cylinder head debate, I definetly want to watch! What is the modern consensus of the crowd? AFRS Pro Action???

 

Pro action over AFR just because of price

AFR's are nice, but its only because they are CNC ported.

If they were rough cast they'd be the same thing as say Dart Pro1's

 

You can get cnc ported pro actions as well. The afr's are superior because of port velocity numbers. Still, it aint worth the price IMHO.

 

I was told once that the proactions have a raised runner (longer intake track) and cross-sectionally are compairable to a 200cc intake runner when they're really 220's

I have nothing to back this up though. A machinist told me about it.

If they are infact cross-sectionally the same then there is 0 loss in flow volocity.

 

How much are The AFR 190's ???

 

I could be wrong too, tpi_roc... Just grapevine information here

 

Well, the trick flows are 64 cc with 2.02 and 1.60's. The intake flows 254.3 and the exhaust flows 189..6. These #'s are not cnc or port & polished. They come with 3 spring rates. 1.26 for up to .520 lift, 1.47 for up to .540 lift, and 1.46 duel springs for up to .600 lift.

I am looking at the 1.26. I have priced them for about $875.
Alot cheaper than the AFR's,

I think they should be a good head. I will be going with the stealth ram and later a 383 conversion.

If anyone can tell me another "aluminum" head for a better price that flows better, please let me know.

Im sure the AFR's are great heads, I just cant see giving 1200-1400 bucks for them.

Thanks for any info.

 

Check out the dart PRO1's

They have larger intake runners which theoretically will cost you low end torque. However Im running the same size intake runner and I dont have any complaints in my car

 

What kind of times are you running? What kind of price for the PRO1's.

Will the PRO1's work good with the stealth ram?

 

I dont know my times yet...

Maybe this friday, I've been asked quite a few times when I do get times I'll post a thread about it. The car will be extremely out of tune however because Im waiting on a laptop car adapater (battery went X_x). The car has insane upper rpm pull, but low end leaves a bit to be desired and from the few scans i squeezed out of my laptops last 2 minutes of the batterys life the bottom end loss is due to knock.

You'll have to do some research on current costs but If I remembered they were the same if not cheaper than TF's

thanks. let us know how you do at the track.

Im interested how the 3.73's do with the siamesed runners and intake. Im getting ready to swap from 2.73's to 3.73's. Everyone says they bring you out or your rpm range with a tpi. The siamesing should give it a few more rpms.

 

Yea it would.

But in all truth I'd LOVE to have my 3.42's back.


The 3.73's are fun in town, they suck on the highway (bad) and at the track. Even if you take your car to 5,500 you often pass the traps pegged and waiting for the 1/4 to end.


Especially with an auto and no B4C valve.

 

do you think I will be ok with the 3.73's, I will be running on a 1/8 mile track. With an occasional 1/4 mile run.

 

From experince, I can tell you first hand that the trickflows workmanship is a bit to be deisred! I had tehm on my vett and they performed great, however, after 7K miles the guies were shot! And they Were the G2 heads that supposed to have had the valve guide problem fixed! Not happy with their workmanship at all! But for the price, they are a great performing head! I recently pruchased a set of AFR 190's and they far out perform the tws heads and I can get them for 1300. Let me know if you are interesed and i'll send you my contact. And i understand the cost issue! The $900 price tag on the tws heads is very attractive! My experience is you get what you pay for.

C

 

Yeah, for the 1300 I could have the stealth ram and the heads.

I could have the valve guides redone later, or maybe before I installed them.

What do you think about the dart pro1's tpi-roc is talking about?
I can get them for 825.

 

Pro 1's might even have a cnc version if I remember....

 

well i gots to put my two cents in here.... if the trick flows are so terrible then why do 9 out of 10 rustangs have them or canfeild heads on em? to me, for the price... i'd get em if i was on a tight budget.... actually, if they flow over 250 cfm i might get them instead of my afr's.... the thing you must look at is two things... 1: port to flow carheicteristics... a head that flows say 200cfm with a 220cc intake port is worse than a head that flows the same with a 180cc intake port.. because the 220cc head will give up tourqe because of lower velocity.. or "suction" at low rpm's 2: flow @lift numbers... a head that flows say 250cfm at .400 lift is far superior to a head that flows the same at .700in lift..

this is why afr's stand out.. they flow much better at mid lift, than others at max lift... this is why heads are a serious consideration, that requires a well thought out plan on what the vehicle will be used for... theres no reason i would buy a set of pro action heads that flow 280cfm at .700 lift.... when i can get afr's that flow the same at .510 lift... to me i'd get the tricks, have em ported, get the stealth ram, and have fun knowing i've just added some real hp!!!!

hey wayne... ever try canfeilds? :rockon: www.canfieldheads.com

 

I think you need to realize the availiabilty of heads for SBC vs SBF, 9 out of 10 mustangs HAVE to run trick flows.

 

Hmm, jeezus man haven't you heard of spell check? LOL

I before E except after C, and in words such as neighbors and weigh.. cheers, Bob

 

dude look at the time of that post... i was tired... it was like 2:00am and spell check was the least of my worrys.... anyway, mustangs have just as many head choices as chevy guys!!! the point i was trying to make is why suff a huge lift cam to get the same flow number as on other heads.. thats just silly, and shows how weak the pro's are.... so far people have said go with this one or go with that one, while not even having a good reason why... price? lets just say you get what ya pay for, and to me the trickflows are worth it!! they offer outstanding flow and good pricing and perform at the same lift number as the afr's.... just imagine what a little porting will do on the trickflows!!!

 

I would get the heads first and the intake later. There might be a StealthRam on my motor someday. The problem with the Twisted wedge heads was people installing them and not knowing how to set up the right length pushrod. If you dont the guides will wear out fast.

I have the Trickflow 23* heads on my car, My car made 306 rwhp and 419 rwht with 20*of timing, one blocked cat, stock y-pipe, and small tes headers. I have sence fixed the cat and my detonation problem. Installed a better flowing exhaust with SLP 1 3/4 headers. The car pulls like a freight train now.....I get a big grin when I read posts like these saying not to use these heads.

 

I just finished installing my TrickFlow heads last night. WOW!!!
I siamesed the intake while I had everything apart. Before my car seemed like it was running out of steam by 5200 - 5300 RPM. During the test drive, I hit 6500 with out even realizing it. It pulls so damn hard now at the upper RPMs, I definitely need a rev limiter if I plan on keeping the bottom end around. Sure, there are better heads than the TrickFlows. But not all of us can afford to have the best of everything. If you're on a budget, than the TrickFlows rock.

 

Dude, take a chill pill! TWS heads perform great, however, the workman ship SUCKS! It's well know that you get what you pay for! As far as the flow numbers, I beleive afr's flow a good 20 cfm across the board over the tws heads. Guess it depends upon the rpm range of the cam you are using in reguards of the intake setup? If you are not planning to go much over 5000rpms, a better set of heads will out preform just about any bolt on mod. I put the slp runners on and then ported my intake system by hand and i pull up to 5700 rpm's (with out running my supercharger). I only run up to 5400 wiht my supercharger, don't want to over rev it! The TWS heads were desighned for the rustangs and work well with their particluar setup, however, with the chevy's they are a bit to be desired! Take it from me! I purchased them, a good friend of mine had them on his vett....SAME STORY! Perform great, workmanship..........spend the extra cash and get the best! And don't feel too bad about the spelling! You are not being graded and my spelling sucks too

 

Just to let you know, the tws heads i had were the Twisted Wedge Heads, not the 23 deg heads. The twisted wedge heads perform better than the 23 deg heads, howver the durability of the 23 deg heads is a huge improvement over the twisted wedge heads. I called tws and spoke to them about the 23deg heads when I was building my new engine. And about the huge price difference, Like i said before, the 23deg tws will run you about 1000 ball park, I can hook you up with AFR's for 1300 shipped to your door!

 

oh well, i guess the afr's win again!! i know i'll be defanatly purchaseing them now... me and bluegrass can get em for 1195 we just have to go and pick em up..... i'd have to say for 800$ and no porting for them to flow over 250cfm is damn good.... i think it has come to a try it for yourself and see kinda thing now... there's so many mixed emotions that it even made me think for a minute... yeah the trick's are a good head, but afr's are the top of the line i guess..... well wayne your in a fix dude.... keep me posted on your decision, i gotsta see which one you'll be getting!!!

 

Well I can get the 23* for 850 bucks. I think I will be satisfied with the trick flows. For 1300, I can get the trickflows and a stealth ram. This should bring the rpms up to what I need.

AFR's are nice, but I dont require the best.

Thanks for the info thought. I really want to know which would give me more hp for the money, a stealth ram, or the trickflows.

I want to add both, but may have to choose only one for now.

 

I run 11s with stock TrickFlow 23 degree heads. Yeah... I'd say they're GOOD ENOUGH!

 

Sounds good to me. I will be going to a 383 later on.

You said the heads are stock, so you did not do any porting or anything to them right.

 

I was looking long and hard at Trickflow heads myself... I have heard they are somewhat unreliable. At the same time they have pretty respectable flow #'s from .200 -> .600. The Pro1's are strictly race/drag heads and they're not really even that good for those applications... Their streetability and low end torque leaves a lot to be desired. I know I don't want to have to run a cam with at least .600 lift to put down some decent power... AFR makes the best heads you can buy period. Not all of their heads are CNC'd either.. Even when they're just a casting they are extremely high flowing. There really aren't any other heads that compare aside from the Victor Jr's which still don't really match up and cost about as much.

 

I just bought a set of trickflows 23* with upgraded springs for $910 shipped. From these guys http://www.jdsperformance.com/index....=229&fcmd=item the cheapest place I could find.I looked in to AFR heads but after you get the 68cc or 74cc chambers milled down to something more usefull your up to around $1500. It wasnt worth $600 more to me at this time.
