Will these heads be a good bolt on to mach my lt1 cammed LO3?
I read they have heat crossover does that mean they are stock EGR compatible?

billybird

im buying those heads for my 89 formy tpi car with comp cams 262 and slp runners should give me alota power..im sure they will work good on a lo3

thomas1976

You know if heat crossower is for the egr or are you going to run without? I couldent find the cca 262 cam you mention whats the part#.

thomas1976

Can any one give me some imput?

And how much would these heads need to be milled for best performance up to 5000rpm?

http://WWW.trickflow.com/partdetail....6&autoview=sku

Or would I have similar results with ported 187?

PatrickL

For that price you could get some GM fastburns.

Chevy High Performance Magazine put a set of the Trick Flows on their 305 HO '83 camaro about a year ago but I can't remeber the results.

BTW, I'm hoping to have my LT1 cam and World Products S/R Torquer 305's on by the middle of next week. I want to find a dyno nearby so I can have some real data.

thomas1976

I need a head were I can reuse the 3704 (if not it becomes just another expensive pece of junk) bolt egr and stock accessoris with excellent performance.
I was locking at these heads because the combustion chamber ressembles the vortech's, at least from a inexpert observer point.

Rock n roll. I cant wait till you dino yours that will give some good imput. Hope you get at least 260rwhp. Did you gasket mach the exhaust?

PatrickL

I understand about the 3704.

I found the magazine article (Chevy High Performance June 2007 beginning page 36) - and they used the Trick flow heads. The heads, cam (.469I/.484E with 1.6 rockers), and edelbrock TES added 53 horsepower and 45 lb-ft of torque at the rear wheels. The car was a carbureted 305HO.

thomas1976

Here is some information I received from trick-flow.

1.-You would not have to mill the head. Our head is
going to raise your compression a little bit anyway. What
compression are you trying to achieve? Is this a stock short
block with a cam or did you change the pistons?

The heads do have an EGR port.

They are a replacement style head the only thing you will need to
do is measure for the pushrod length.

I do recommend part number TFS-31400513 Rockers.

2.-With our head you would actually be gaining compression and
making more power.-

Hey Thomas,

I gotta tell you that the dealings that I had with Trickflow suxed. AND so did the quality of the parts....

AND you asked me about shipping on the posi's..

When I went to the post office they looked at me like Al-Qaeda.......must have been the beard and the 9mm.....lol.

Anywho shipping to Switzerland seems like nothing but BS. Heck at work they wanted over $250 for shipping .......so that's killed.

As far as the heads if I was in your shoes I'd spend the money elsewhere........

thomas1976

So I should stay away from trick-flow heads?

Were else would you spend the $?

DM91RS

I would first get the rear gearing better. It will make a good difference.

Then what do you want to do with the car? Daily driver or track days car or drag car or road course racer?

How do you normally drive the car?

thomas1976

Id just like to get some decent power below 5000rpm.

I know gears will make a nice difference.

DM91RS

Now that I have gone to the link.......$1210 for heads? Ouch......


305 heads that is........

thomas1976

If I buy new vortech's, GMPP manifold, plumbing for the EGR and ad shipping there will not be much difference.

What do you think of the TFS-30310006 's combustion chamber?
Also what Trick-flow parts did u buy that were poor quality?

DM91RS

Once upon a time TF used K-motion springs. I have had those break on more than one occasion. The TF's might be better now....I don't know. Just going from past experience. It's your cash and they might be great. Alum heads are great if you can afford them.

Good luck.........DM

The thing with most aftermarket heads I have seen, is all with teh components (with the exception of pro-toplines, then they have all sorts of issues). Thomas, I really like the GMPP Fastburns, they have proven to be really good performers.

I think I would also go with a little more cam than the LT1 cam, if you are spending for heads like these. A little more cam will go a long ways when you have heads that really flow well at the higher lifts and have the larger runners.

Ohh and Thomas, I have a friend who works at fedex, so we can ship stuff at at 90% off. .

thomas1976

Are you sayin the aftermarket components are not anough reliable?

What part# are the GMPP fasburns you like? The one I found have bigger intake valves, no EGR and 58cc.

For the LT1cam I tought of using 1.6 rockers some day.


And Dewey im still loocking for a good deal on bumber and intake

Dewey316

THe part number is.

12464298

Do you need EGR? That really limits the options. Or do you just need the apperance of EGR.

And for the bumper and stuff, no worries, If you happen to spot one in a junk yard, or used for a good deal, just let me know. I am in no hurry, this is how my car is sitting right now

http://cascadecrew.org/John/turboswap/install3.jpg

(I am putting in a 10v turbo now, it had a N/A 20v motor. But I have the turbo manifold, and 20v head still, so if I get ahold of some S2 or RS2 intake parts, I can go that route at some point in the future)

thomas1976

That are the ones I saw, but arent the valves to big for a 305 low rpm engine?

You are right about EGR, S/R's or trickflow's.

You are going to have a fast car wen you'r done with that old audi. I hope my ta will be respectable too wenn Im done with it.

Hey Dewey, for a second there when I saw that link I thought you were doing a turbo swap on your Camaro haha. Anything new going on the Camaro?

Dewey316

Nothing new motorwise right now, putting new brakes on soon, hopefully a 9" this fall, then I need save up for a T56. After those things are done, then the next project will start. Gotta get it ready for 500-600 HP.

500-600 HP is good, will TBI be attaining that level?

Dewey316

DM,

That is not a mess, that is a FUNCTIONING garage. , that was also at my old place. The new garage is slightly more organized.

http://cascadecrew.org/John/lights3.jpg

BronYrAur,

I want to use TBI, I am still desciding. It may be dual TBI's with EBL, it may be a 4bbl TBI, or I may go with single-plane port injection. I'll descide when I get there. I have a lot to do, I have the block and crank, I need to build the bottom end, and get machine work done, and also heads. That is a ways off, still probably a couple of years, consider the other stuff I need to do to get the car ready.

Nothin like a little zakk wylde to get you in the mood to paint haha. I just threw in a new O2 sensor, that's about the extent of my "project" this summer, very involved.

Dewey, TBI would be awesome to pull off on a motor like that, but I don't think I could choose it over something like single plane MPFI, I've always wanted to set up one of those.

DM91RS

My friend paint is very subjective.....haha.....

Summer project my butt, You lazy college types just wanna drink and get laid.........LMAO

All I can say is enjoy it while you can......

BronYrAur

iTrader: (1)

haha dam straight

Dewey316

BronYrAur,

Yeah single plane MPFI is the bee's knee's. Going with ported fastburns, and the ramjet intake isn't out of the question either. A lot of choices are going to come down to cost, and what heads I descide to use also.

and enjoy those crazy college days. . Another peice of advice. Don't get married. Then you can also enjoy the rest of your 20's. haha.

And DM. Love the Zakk Wylde, I was a fan of his when he was with Ozzy, and still am a fan now that he is doing the BLS stuff too. Good music to paint by.

DM91RS

John,

Zack has some good songs and as you know by watching the video he doesn't cut the posers any slack........ LOL

DM

PS...just to keep the tech in this thread I've also been moving heads around the shop....

Sorry thomas1976 I hope there is something in this thread to help you get your heads selected.....

BronYrAur

iTrader: (1)

John, I like how those Fastburns look too, a friend of mine is swapping some on right now, makes me want more power. At least you're avoiding the urge for more power before you build the strong base, T56 and rearend. I've been enjoying these college years for half a decade now haha.

DM, I love how he just threw in a "limp bizkit sucks" out of nowhere in that song ha.

-Jim

DM91RS

Half a decade.....you sux......lol......I'm just jealous.

Yep Zack kinda wears his heart on his sleeve with that song......

Dewey316

Yup, I have enough power to have fun right now, and with the eaton, TA Girdle, and richmond gears, and a WC-T5, it hasn't broken in all these years. But, the next project involves a 327, solid roller cam, and 2 eaton M90's that I have sitting in my garage. I'm planning to rev the bad boy up to about 8k, so it should be a fun little motor, but I want everything in place, so I can enjoy and use the power, without worrying about breaking it.

A decade in college eh, haha, I am on the 16 year plan (at least). I have like 12 credits, and am 27 years old, do that math on that.

DM91RS

Let's see....now carry the 4, add the 8, divide 6, multi. x 3.14....uhhh...

Oh he11..just call me a dumba$$, now how long you been in school?

Dewey316

Lol, well I graduated 9 years ago, and have take a total of 3 classes in 9 years.

DM91RS

*****..........

DM91RS

Ok.....back to the tech.....

Thomas....you decided on any heads yet?

AND you will have to forgive me but did you state that you did or did not need EGR?

I also ASSume that it should work with your performer intake.

thomas1976

No havent decided yet.

Yes I need EGR and they should work with the 3704, thats why Trick Flows are interesting.

I use the car for summer road trips and as dailly driver, excep by snow and ugly weather. Therefore reliability comes in first place.

Im still courious about PatrickL's results with S/R and lt1 cam.

DM91RS

You might be interested in Axoid's post's starting with this one......


https://www.thirdgen.org/forums/tbi/...html?highlight

PatrickL

Thanks DM91RS! I knew that somewhere in the archives someone would have dyno'd that combo. I'm hoping for 250-260hp at he flywheel and that coincides with about 212 at the rear wheels assuming 20% loss.

I have edelbrock TES, no cat, American Thunder cat-back and roller rockers, and 3.73 rear with the T5. - I'm aiming for 14's in the 1/4.

I farmed out my head swap and probably shouldn't have. Maybe next week I'll get it back and start the tuning process.

Dewey316

With a descent set of heads, and a cam, you should blow that number out of the water. I got just over that 212 HP number to the wheels, on the stock swirl ports, with an untouched TBI unit, just intake/cam and tuned it.

--John

DM91RS

I also thought that you had higher numbers with the ported stock heads that you had.......416's IIRC

thomas1976

You have any idea what numbers Axoid endet up with the S/R's.

I could only see it resonable to swap heads for at least 250rwhp.

DM91RS

I searched a little bit earlier let me see if I can find it

DM91RS

I can only find this

No hp number that I can find. IMHO....I would not buy those heads for the price. You can do as well with ported stock heads. If I had it to do over especially with gas prices I would stick with the heads you have add the LT1 cam, better springs, rears gears and tune the poot out of it.

AND to top that off do a search and read up on Beast5spdGTA's very good documented post's with the stock heads and cam and John Deweys very good documented post's on the same set up and then John's info on ported TPI stock heads and a cam swap.

If I had this info years earlier I would have gone a different route.....IE: simpler to tune and better on gas and the cash.......
