    I know the vortecs are great right outta the box, but Im going with the TBI setup and was wondering since I'd have to by the gold plated intake manifold for this, what are some other heads that are comparable to the vortecs?
    I have read up on the World S/R Torquers and the sportsman II's. They appear to be about the same price as the vortecs along with the special intake. So I mjust weighing my options hear fellas.
    Any info?

    ya know what I debated this exactly issue... when it comes right down to it you can buy the heads and the intake for the same price or cheaper then you could buy any other heads...

    I'd think this would still be the best bang for the buck!

    Thats what Im thinking. But I dont have enough knowledge to really make a sound decision on my own in this particular field.
    Also, Im wondering weather or not I should replace my stock intake manifold anyway, if so I might as well got with the vortec and get the vortec tbi intake and take out 2 birds with one stone.

    I've run both the Vortecs and the S/R Torquers on back to back 350's.... The Vortecs are better!

    you know what after having just having done a major job on my engine the only part that is the same as when I got my k5 is the starter, and the t-case... it ended up costing me a lot more money then I anticipated... (I'm sure there aren't too many cases that are quite like mine).

    I'd recommend 2 things; 1 it is a lot cheaper to go stock... why do you want the extra power (i.e. how is this thing gonna be used, does it really need it). remember the more power you have the more parts you are going to break...

    when I do the engine in Insane Ewok (off-road k5) (which won't be too long from now) I am going to go all stock except for a cam, and possibly an intake.

    if this is gonna be a trail rig rebuild the engine if it needs it, and otherwise leave it along, and put some $$$ into some off-road stuff. just my $0.02...

    yea, but I don't think they have been drilled for TBI intakes...

    Huh? Not drilled for TBI intakes? No offense but, to my knowledge there are 2 different patterns, Vortec (1 bolt each corner, straight up) and pre-Vortec (multiple bolts at an angle). Other than the Odd-ball Vortec TBI intake that has recently become available, all TBI intakes should fit the old pattern.

    Russ,
    The center bolts on the TBI intakes were at different angles than the outer bolts, unlike the pre '86 heads. There are three different intake mounting styles for the small block chevy.

    Cool, learn something new every day. I thought there were only two. So what does that mean for guys doing a TBI swap? I thought a TBI swap was just "bolt on" affair for carb'd engines. I guess it was a good thing I got my TBI 350 complete rather than doing a swap. I would have been in for a nasty surprise. [​IMG]

    You can elongate the center bolt holes on the TBI intake to make it work with the early style head, but it is a pain in the butt.

    Well, I kind of have a different opinion, but I guess that's why you posted. I just put my 383 together last weekend, and after many problems in getting my stock 993 castings worked on (among other problems), I decided to go with the cast iron Sportsman II's. Many things factored into this, including the fact that my buddy ('73 K5) upgraded to Vortec's after pulling some rocker studs on his stock heads. He gave me a good deal on his Performer intake, and Crane roller tip rockers, so, for me, the overall price was better, and the potential for more power was also there. The Vortecs are a great head for torque and mid range power, but from what I hear, they run outta steam on the high end, but that really doesn't matter in our rigs. The Sportmans support up to about 450hp outta the box, and with some porting, can support up to 650hp. They were only 25 bucks more per head than the Torquers (about 800 per pair assembled), and they have bigger valves, and under 3000 rpm's they flow like a 170cc head, but above that, they pick up, and flow the 200cc. All I can say is that if you want to look at my profile for specifics, it seems to be working REALLY well for me, and has some serious pull, just ask '73 K5. In the end I would say that you need to think hard about what you're going to be doing with your rig, and your checkbook will also be a big factor. Good luck,I hope this helps.

    Stupid hurts

    Be carefull looking at adds. The Vortecs are around 400 bucks a <font color=red>PAIR</font color=red> where the others, including world have some tiny little print that says <font color=red>each</font color=red>. With the Vortecs allow another 100 bucks for self guided rockers too. Read the adds very carefully.

    I got the rockers from sdpc2000.com, and it was like $63... including shipping so they aren't quite as bad as $100... I think pace parts has the best price on the vortecs, but I'm not sure what your membership discount is with sdpc is so you might try there for both of them...

    Well after readying the TBI upgrades article in the Petersons last night Im sorta leary about the 383 now. It said that Hot Rod built a 383 with a stock TBI with SPortsman II heads and they said that they couldn't even get it close to running right without a custon chip from Turbocity and even then from the way the writer put it it still had problems. So now I need to find me the Jan. 2000 issue of Hot Rod Magazine to get more details. Does anyone have this article?

    MUDNUTT just built a 350 with Vortec heads. Look at my link in my signature and you can see some of the pics. Anyway he put it in his 79 Blazer and it screams!! (not just because of the gear drive either) I honestly think it will outrun my 383. It will be interesting on the 25th to see what happens because we have the same exact setup (465, 205, 3.73 gears, 33x12.5x15) but mine is in a 72 and his is in a 79.

    Basically I think a lot comes down to what can and can't be done with the chip. I have heard of a couple guys running 383's with TBI and no real hassles. You may want to give BlazinOR a pm and see if you can't get the # for the guy who did his 406 tpi setup.
