vortec VS fuely heads

[SS10]

Wich would you go with the new vortecs or the old camelhump heads I am running stock 1.94x1.5 76cc heads right now with a solid roller cam and roller rockers.

[my454s10]

it really depends ....the vortes heads will only take a cam with .450 lift unless you have them machined however they done make a lot of power and at the same time they a limited by there own design meaning that they do not respond to porting ...the vortec heads will make 400 horse or so in the orginal form which is pretty darn good..but with a hard hitting soild cam and fully ported camp hump head with 2.02 and 1.6 valves the possablies are more ...as for the money than the vortes are only 400.00 a set and are worth every penny of it ...if your motor is going to make more power than 400 horse power than the older camp hump heads are better...thats my 3 cents worth http://www.s10v8.com/images/smilies/icon_biggrin.gif

Yup. Exactly what he said.

Also the Vortec heads change the compression ratio considerably they have like 58cc chambers.

Just remember the Vortec heads require a Vortec intake manifold. The only ones I have seen are from GM or Edelbrock and they are not cheap as compared to regular SBC heads.

My 83 has Vortec heads because when building I wanted a certain build and my machine shop told me to run the Vortec because of 64 cc chambers which gave me the pant leg snap out the tail pipes.

I am running a Edelbrock RPM performer not for the Vortecs they just drilled and tapped for my center head.

The shop tailered the motor to the rest of my drive line and at only 375 hp its a blast, and best of all the block is set up to great to add any better head and cam at a later date but first I will work on getting the tires leave a little less of their mark on the road.

i did a motor with the vortec heads and i just cut the two center holes on the reagular intake to where it would fit the heads...it\'s a lot cheaper and it worked great

[s10dragtruck]

look at the flow number its proof vortec are best bang for buck and look at the power if ported

Why not just go with a set of AFR\'s or World Products heads. Then you can talk about bang for your buck.

[Knanthrup]

Vortec heads are only $400? Is this just from your local dealership?

[lil_yellow_truck]

in all the years that I have been building if you find \'67 fuelies then they have a 2.02 1.94 valves thoes heads are the best ones i have used, but they only come one the 350hp 327

So you\'re trying to tell us that technology hasn\'t improved in 30+ years? New heads flow better and have much more efficient combustion chambers than the old ones whether they are aftermarket or the Vortecs.

[lil_yellow_truck]

no i have not used any aftermarket or vortec heads so the fulie heads are the best ons i have used

Scoggin Dicky sells upgraded vortex heads that will handle a 550 lift cam and also sell these heads as a package with edelbrock intake for $900. www.Sdpc2000.com

[s10dragtruck]

vortecs are on ebay all the time for $300-$400 but they dont usualy have the rockers but who cares why would you want those crapy stamped 1.5 ratio rockers get roller 1.6 and new .600 lift springs that fit without mods for $20-$40. Port the heads get a 235 dur cam @.05 and rpm intake and your in the upper 400 hp range on a 350.



lightweight look at the flow specs for the vortecs and your heads (last on the chevy sb) the difference is 2 hp and i bet youd make the same power with either head and still have an extra cash to pay for the gas for a while. yea you do have more room for porting but stock the vortecs are better bang for buck

[EZrollin]

I don\'t know why anyone would want to use old \"fuelie\" heads,not maked for unleaded fuel,probably need rebuilding. The money spend on them would be betterspent on Vortecs or aftermarket heads. JMO

[rudedogg]

thats what i am talkin about,the vortec heads flow 170 cfm out of the box,they out flow the gm bowtie heads stock for stock.cant go wrong with them..i would hate to think modern day technology would not be a benifit,after all look how far we have come. http://www.s10v8.com/images/smilies/icon_biggrin.gif use what you want,build it your way and enjoy your creation.

[mommasboy]

I will still disagree about the stock vortecs over Worlds or AFR\'s. Either of these heads will grow with just about any motor you wanna build in the future. Oh and if you could show me the flow numbers that show the vortecs flowing as good as the 200cc Worlds(especially with 2.055/1.65 valves that are swirl polished and under cut)

[rudedogg]

i didnt say that they would out flow the world products head.i was talking about out flowing the other factory heads,true if you buy the other heads you have room for race-porting and other detailed work but with people being on a budget the vortecs are not a bad investment after all if hes goin to use the fueli heads he will have used dart,afr,tfs,canfield money.......btw where can you get a set of darts new for 450.00???? i sure could use an extra pair!!!!!!! http://www.s10v8.com/images/smilies/icon_biggrin.gif

[my454s10]

ok.men....its like this in the world of racing ...you dam sure get what you pay for spend 400.00on heads or 1000.00on heads i\'ll bet that the 1000.00 heads will flow better ...period..if you want to make 400-500 horse and just have to have the vortec than go for it than spend some more money and put the bottle on it to make up for the power../im telling you look at the trucks on here and at the tack and see how many are using the old fulei heads or the vortec...old or not a good set of 461 heads are hard to beat.....also look at the old vettes and camros ..like the 350 horse 327 and specila orders 375 horse327...they use old fuelie heads...and they have an carb on them with no fuel injection...some vettes had mechanical fuel injection... http://www.s10v8.com/images/smilies/icon_biggrin.gif http://www.s10v8.com/images/smilies/icon_razz.gif
