Exhaust ?

[714x4lover]

I NEED TO KNOW WHAT SIZE EXHAUST PIPE TO USE WITH A 383 STROKER MOTOR? WOULD 2 1/4" BE ENOUGH? ALSO DOES ANYONE KNOW WHAT BLOCK HUGGER HEADERS ARE, AND IF THERE'S A SET OUT THERE FOR SALE. DO THESE HEADERS HAVE A TENDENCY TO BREAK LIKE THE RAMHORNS? AND HOW MANY MORE HORSES WOULD THIS TYPE OF HEADER GIVE COMPARED TO RAMHORNS? ANY HELP ON THESE ?S WOULD BE APPRECIATED.

Personally, depends on how much you really want to spend on a set of headers.. I am running headers on my truck but the problem that I see is, if I don't keep on top of checking the bolts, I end up having to replace Gaskets.. Also Headers do not give you a boost in HP in Low Range but in the Higher Range the do. Trust me any header will out flow a Ram Horn.

Now if you want to spend around $ 320 + for a set of headers, I am going to buy a set of these after I do a couple of upgrades to my engine, a Set of Sanderson qp1000 Headers!!

Sanderson QP1000

I know a couple of people that ran these and they recommend them because they are as reliable as a Stock Exhaust Manifold but will flow just as well, if not better, then a standard tubular header, give you more hp and torque throughout the whole poweband and all you need to do is use a bead of Black RTV around the flange and bolt them up!! No more Gaskets at all!!

if im not mistaken, all headers give more horsepower.. but then again they get much hotter and spark plugs are harder to get to also. block huggers are just that, the header stays close to the block. heres a picture of the motor in my 71 k20, i beleive the headers may be for a chevelle but i dont know for sure

Actually, years ago, hot rod proved that some of the cheap headers are actually out flowed by manifolds. I about crapped myself.
Seems blackjack was the main offender.

Hooker says 2 1/4 flow just about right for a small block. You get torque and hp down low where you need it. When you go to large pipes like 3 inch there is little to no back pressure left in the system. Remember yo have a small block even though it's a 383 and you have smaller valve and smaller exhast ports than you would find on a big block. The 3's might sound good but your performace suffers. Shortys are made to fit most any application becuse the don't have to bend around frames and steering linkage. They flow a little better than most manifolds Get good ones made of thick gauge metal.

Hi dmnall. How do the QP1000 fit in the trucks? I noticed the they go straight down. Is there any problems with A arms running exhaust pipes to the header? Also are they cast headers?
Thanks
