this would be for a basically stock 350 Blazer that won't turn over 5K RPM
got the money?
best headers on the market. You would just have to see them is person to appreciate the craftmanship.
those look just like my thorley tri-y's. which i love by the way.
just out of curiosity, do you thornleys have ball flanges or the standard tree bolt with gasket setup?
are those the stainless?
they look ceramic chromed or jet hotted or whatever to me.
Those are sweet headers, but I don't really want to put more then $200 into headers. I want the most torque for my buck.
I have a pair of Flow Master 40 series collecting dust in my shop. 2.5 inchers... thinking about throwing those on for good measure!
oh yea, I'm dumping the cats too. I live in Oregon.... No emissions, yet.
don't know about torksteps but afterburners are good cheap headers. the coating comes off real easy but they make good power. Combonation between a big tube header and a tri-y. Sounds good. I have a pair on my 355.
I'm running Hedman Elites on mine, about $250 last I checked Summit or Jegs, 69890 Hedman number IIRC.
Pretty pleased with them, only problems are #5 plug access (don't use a socket!!) and some shackle bolt interference, but from the problems most people have with header fitment, I think these are pretty tolerable (and easy to fix or work around) problems.
Coating seems pretty durable, and I definitely like the ball/socket design for the exhaust pipe end, which is pretty expensive to buy seperately. I'm not sure that there is a better all-around header (if your criteria are like mine) out there at that price.
Just depends on how much you want to spend. a pair of afterburners in jegs are 130+ or - 10 bucks..... the y pipe for 89.00.
not sure but i think flowtech makes a system for the headers if you want to put one on later.
I'm going to go full 2.5 inch dual exhaust on it.
Think I'll go flow techs, just repaint them.
I would imagine headers make a big difference on these old chevy V8s, just like they do on the chryslers, No?
yeah u will feel the difference right away. youll hear it too even with the stock system. More response and about 15-20 more hp, it will pull harder and be snappier but if you put headers and dual exhaust on, you ought to think about something to let her inhale better. YOu will see another 20 hp with a manifold and another 20 with a chip or with a holley tbi. Also could put a high pressure pump in. I have all this and alot more on my 355 and the thing is a beast.
paintin the afterburners is the best way to go. i plan to do it when i get a gun.
It will eventually get an Eddy intake of some sort and a Comp 4x4 camshaft. Something that will run to about 5300 RPM.
So are Doug Thorleys headers worth more power then the others?
Not really. The one test I've seen (car craft a couple months back, I think it is even on their site) showed that the Thorley's lost power (compared to long tube headers) everywhere except in the midrange, and the overall average I *believe* was DOWN over "standard" headers.
In any case, they didn't live up to their claims IMO.
Of course, like with everything else, there are other variables such as tune and after header pipes, so you always have to think about that stuff.
