why would you go and spend $400 for a Scoggin dickey tpi intake and $450 for a pair of vortec heads only to have them dropped off to have screw in studs put in and better valve springs when you can just take the $900, plus $200 more and get a pair of complete aluminum edelbrock heads that are much better then the vortecs. i have a LT4 HOT cam and was thinking of buying the vortec heads but after thinking about it and looking at my other options i think its better to save for edelbrock or other heads and keep my stock highly ported intake and not have to drill a hole on my slp headers for a heat crossover. what do you guys think. is it really worth it.

tpi intake 400.00
vortec heads 450.00
screw in studs 30.00
machine heads 100.00
valvespringsLT4 35.00

grand total $1,015

all prices are estimites


edelbrock aluminum heads $1,100

 

might wana call orkin for the estimites

 

orkin??

 

The vortecs and edelbrocks flow pretty close to each other.But its not just the flow.The vortec's chambers are a MUCH better design than the edelbrocks. And the high swirl of the vortecs will most likely make more power.

 

so how muh more hp can you gain from a hot cam and vortecs on a SD tpi 350 lik emine. check below for mods. i just want to spend my money wisely and be happy with what i buy.

 

What kind of crack are YOU smoking ? LOL I wanna some of that!

Edelbrock RPM heads make 420 HP on a carbed 350 with their cam. It will take your Camaro in the mid to high 12 second area. Show me vortec cars that make anything close to 400 HP and I'll buy you a beer.

 

I think the vortecs with the better intake will outflow the edelbrocks with the restrictive stocker. As for head vs. head I am not sure.
Good heads & Good intake = $1000
Great heads & $hit intake = $1100

Your choice... just my $0.02

 

i totally agree about the price of the vortec's although i'd rather use tfs heads for the price.

 

Well, Chevy High Performance built a 350 with Vortecs making 422 hp last year. Hot Rod made 460 hp with them on a 383 in the March issue. Everyone now thinks they can hit 500 hp with the right combo of parts.

Where shall we drink that beer?

 

Make fun of the vortecs all u want but i am running a lt4hotcam equipped vortec headed tpi motor in my 91 formula :-) i will tell u one thing it sure as hell is one rocking combo... kinda wierd since i still have my stock converter (2500 coming soon) it wont blow the tires away from the line anymore but from 20 to about 50 it will boil them at will :-) it is quite an amusing package :-) u have traction the 20-80mph isnt even funny for having a long tube runner setup :-)

U punch it to pass people around 30-40 range and u have to hold on so u dont lite them up and spin the car out
the vortec do make power and u can get heads setup from wheeler for 550 lift and 1.60 exhaust valves for 515 a set from PACE (whom i did my gp on for the vortec tpi conversion) add 30$ish for studs and your good to go

I did port my own heads, nothign too serious but did clean up the shortside radius on the intake and exhuast and did some lite porting /cleanup on the intake

going easy on her for now until i get my extreme richness problem cleared up and my 2500 stall in so i can do my transgo shift kit 500 boos valve and vette servo al it once so my tranny lasts behind the might

and ps i have about 1500 total in my engine itself including the 1.6 rr :-)

I'm kinda wondering if you're the one smoking the good stuff SEVERAL magazines and many friends of mine have built 400+HP vortec 350 with BASIC CHEAP parts. My Formula had stock unported vortecs, .015 thin head gaskets, Comp 268 extreme cam, stock 40K mile dished pistons (so around 9.2:1) stock valvetrain, RPM intake, 650cfm holley, 1/5/8inch headers and good gears and I squeezed a 12.9@108.5mph out of it. That has GOT to be near 400HP at the crank. This was in a full interior, AC, T top, full weight car. My friend had a similarly setup Nova that weighed nearly identical, but he was running RPM heads and the rpm cam..........I ALWAYS smoked him in races.

I'm currently building a fresh 357 with better pistons, high CR, FULLY ported vortecs with all the goodies (screw in studs, guide plates, ect..) full roller rockers, Super Victor intake, and either a solid roller or a Comp Extreme 284 cam in hopes of going low 12's on the motor, low 11's on a 150 shot. Now that has got to be more than 400hp

 

3.8transam, what pistons are you using and what is your compression ratio. i already have the hot cam and if i can get a pair of the vortecs cheap then maybe i will try this combo. i have a 91z28350tpi. basically like yours. i see vortec heads on ebay going for 300 bucks.

 

You need to buy another TPI intake for whatever set of heads you get if you want to make any kind of decent power, so figure that into the price. The stock intake sucks and will hold you back no matter what you get. Vortecs with the better intake will beat the **** outta Edels with the stocker IMO...

Just about everybody doing a Vortec buildup hits 400ish hp, but not with TPI. I'm waiting for solid numbers with the SD intake and a hotcam...
