Hey need a set of bad *** heads for my 383 stroker, almost done.

I want to know about the vortecs. who is running vortecs????

I was considering the vortec tpi combo, vortec heads and base.

also what will the compression be with 64 cc combustion chambers and 10cc dish pistons???? I need to know

Anyone who is running vortecs or have run vortec heads before let me know. ARE THEY GOOD !!!

check out wheelermotorsports.com

they have vortec heads, machined for retainers and guide plates and ferrera valves your choice, and upgraded springs to 550 lift for only 599!!! sounds like a dam good deal to me.

WELL ANYONE WITH THE VORTECS PLEASE REPLY IM DESPERATE.
IF YOU HAVE ANY INFO IT WOULD BE GREATLY APRRICEATED.

Ha, wheeler is in my town used to have a whole in the wall then had a big visable building but moved to behind a skating rink. Anyways from what I've seen the Vortecs are a kick *** head. Not only do they flow better but they use the center bolt valve covers, have a raised and machined flat rail where the valve cover meets the head and they also use a trick plastic gasket that has silicone/rubber sealing rings and oh yeah they have a better designed chamber. Don't know it you know it or not but you have to get your own screw in studs and guide plates cause wheeler doesn't supply em with the head. Also don't forget to use a chormemoly/hardened push rod with the guide plates.

Vortec's are really the best bang for the buck heads you can get. They make 420+hp on a mild 350 motor, and that's without port work. They will work well on a 383 and makes gobs of torque. I would check out the SDPC vortec TPI base since you're planning on going that way. It flow a lot more than the stock one, and there's extra material there so you can port it out.

Anyone used the aluminum Vortec heads? I'm gonna be working at a GM dealership and am hoping I can get a good deal on a pair of aluminum vortecs. Anyone?

kfoley

I'm guessing you're talking about the Fastburn's, right? They're good heads, flow more than cast iron vortec's, plus you can run higher compression/more timing, and weight reduction. I've never run them, but I've heard good things.

iroczman380

Hey thanks for the replys

iroczman380

Hey Can anyone give me some info on what this setup might run in a thirdgen. and maybe some horsepower numbers?? I have dyno 2003 but I cant get it to work right.

(Im only 17 to)!!!!!!

Here's what I came up with on Engine Analyzer:

iroczman380

hey thats awsome!! just curious are these numbers

rear wheel or flywheel??

Thanks alot for the helP though!!!

kfoley

Those are flywheel with accessories.

Riley's35089rs+

that is on upgraded vortecs , Right....Stock vortecs suck after 5ooo rpm....they crash........

jpk91rs

the iron vortec heads are awesome. All of the dirt cars in the modified classes run them at the track where we race. I run vortec heads on the '72 Chevy PU in my sig. They pull to 6500+ and never run out of steam. The Fast Burn heads are awesome. I have run them on a barely streetable 408 and they arre awesome. I am going to run them again on my 383 tbi in the 91 rs. In my opinion you cant go wrong with the vortec head or the fast burn.

DUDE your idle HP is almost as high and higher than my peak with my crapy 2.8

GL just trying to get to school lol. Man GOOD LUCK in the rough weather.

iroczman380

hahahah, youll get a fast car some day!!! ill sell you my old 350, it would beat the sh*t out of the 2.8.

Just to let you know i hope that dyno is a bit off, I was expecting more hp then that. the torque is about right though. well see.

Im going for at least 400 horse at the flywheel and
at 400 ft lbs at the rear wheel.

I THINK I CAN I THINK I CAN I CAN!!!

then its time for a 50 shot, to drop it into the 11's (i hope) with a ****load of tuning!!!

Hmm if i can find me a new car, like a 3rd gen firebird with ok body and interier i may just supe that up with a 400sb and then well see who has the fastes 3rd gen at school

GL 5.0's LMAO

iroczman380

Talk talk talk and more talk!!!!

Do it !!!

JK!!!!

The fastest car at school???

More like the fastest car at any school in our area.

Unless theyve got a viper, or souped up vette they dont stand a chance in hell!!!!

The mustangs are about ready to get there sh*t taken to them.

Even your car could prolly beat a new gt!!!

If that engine is going to make that much torque you are going to have serious problems hooking up your tires. You are going to have to do a lot of suspension work.

He is planing on doing full sub chassy braces and major suspention mods soon to make the car even take off, let alone not to break the car in half.

i've got a set of vortecs on my 350
they've got bowl work and valve job... and were decked a smidge. still the stock vavles... 1.94/1.5's

I couldn't tellya what the exact hp it's putting out, but it's propelled my Z28 to 12.0 @ 112.5 passes many times

i belive they will fit the bill for you

I've got vortec heads that have been treated to a stage III port/polish package and they are badass! The fastest car I've raced and beat so far was a red light race against an '02 Z06. I put 3 - 4 cars on him when I shut it down about ~120.

My heads have been milled to 62cc, intake and exhaust throat work, stainless valves 1.94/1.56 manley (bigger exhaust valves than stock) with 5 angle radius cut valve job, massive bowl job, full polish, spring pockets enlarged for comp cam dual springs (upto .600 lift), there's more but I cant remember.

With forged flatops with 4 valve reliefs, my motor is between 10.3 - 10.5:1 compression.

The best part about them is they look stock! Vortecs heads are an excellent street head.

Mutiny32

Got ya beat for faster car at any school in the KC area. I've got ford buddies that are pushing 500HP.

vortec flow numbers
intake valve...1.940 in............28.0 inH2O
lift: in flow: cfm
0.100 70.0
0.200 139.0
0.300 190.0
0.400 227.0
0.500 239.0
0.600 229.0

exhaust valve....1.500 in .........28.0 inH20
lift: in flow: cfm
0.100 49.0
0.200 105.0
0.300 137.0
0.400 151.0
0.500 160.0
0.600 162.0

these are straight out of the box no port work....match your cam accordingly to the flow versus lift number's no need for a cam that lifts .600 when the heads only flow good to .500 lift....gasket make intake and do a bowel job and good 3/a vavle should be even better (MORE POWER WITH 2.02.........1.6) with a powermax f-278-2 crane cam in 383 with 10.8 compressiom with dualplane man. and 750cfm carb i got 404hp at 5000rpm and 453 torque at 4000 rpm

iroczman380

Well thats all nice that there pushing 500 horse, but what are there times????

i hope to be in the low 12 second bracket. i wont stop f**king with my car until iam hitting 12.1's and 12.2's. then ill put a 50 shot on and drop into the 11's.

so i think ill be around 500 horse with nitrous as well, so what are you trying to say.... ...

My car is a blue iroc and you can see it in the link above. im up at kcir, once in a while, and im sure once in a while will change to often once the 383 is in and healthy.

just for the record isnt this a thirdgen site???? shouldnt we be rooting for the irocs!!!! LOL

Riley's35089rs+

You have to "work the vortecs to get the higher RPM's..in the stock form..they are tough, But in my experience...Riding with 2 friends...bolted on to 350's carbed...they float ...

Pony Killer

Using the stock springs in vortec heads is not a good idea..

they are junk. If your running a flat tappet hydraulic cam and keeping the lift under .500.. there are several options of springs, that are inexpensive and any work to the heads is minimal to get them in there.


I'm running a "z28" spring.. and haven't had a float problem yet.. it's been close to 7000rpm a few times.

Riley's35089rs+

thank you Poney Killer..thats what I ve been trying to say all along......people are so stuck on vortecs...but you have to put a little $$ into them to reap the rewards of there potential..!!

BILLY SMITH

all you got to do to them dude is machine cut down the valve guide boss so the retainer doesn't hit the top of the seals if you use a bigger cam .500 or more lift and open the spring pockets for dual springd or single 1.450 springs .......when you do a cam change you normally set up the heads for the new cam that's spring height and pressure.......but over all it's not that expensive if you do it yourself comp cams sells the arbor's and tools you need to do this for about a hundred bucks

r90camarors

I went with pro topline vortecs for my 383. I believe they are capable of a .550" lift stock. Very happy with them so far. Can't wait until I get that little 2bbl tbi off of there to see what she is really capable of
