I can get my hands on a 3 inch exhaust with 1 3/4 long tube headers. Do you think this is too much on a stock engine and will it effect anything?

Is this a stock diesel ?

No way, if your all or mostly stock you probably wont have enough back pressure. And it will for sure kill your torque.
Might see if ya can just get the headers though.

[trueblue01]

Not gonna help your cause if that is "cause I wanna go faster"!! Sorry, yeah, it is over kill, spend the money else where.

I can get it cheap. I just wanan know if its gunna have a negative effect for now. I will be building a 331 stroker but not yet

[ThreeHonks302]

its not really gonna hurt/damage anything but you will definately lose torque

[cybertech]

Would there be a great deal of torque loss

[93mustank]

Just say no...........

[ThreeHonks302]

prbly quite a bit. I was running long tube headers with an open off road h pipe. This was on a stock engine and once I put mufflers on it I could tell a huge performance increase. It just had no backpressure on a stock engine. If you're really serious about the stroker and gonna do it soon I would pick up the exhaust and just save it until you do the stroker (especially since you're gonna get it for cheap)

i wonder if it would be too big for the 331?

honestly depends on your set up and how its all built. You doing a stroker? and why not just go 347? more HP.

[cybertech]

the engine geometry of a 347 is poor and wears fast as well as the position of the wrist pin and the oil consumption. A 347 is more to get the max hp for the drag strip not for a street car to last. I will be shooting for about 450hp at the crank out of the build

dude your crazy..
if you show me a 347 is burninng or leaking oil.
ill show you a shitty engine builder..
347 ftw!

[cybertech]

You can't change the wrist pin from intersecting the oil ring. Which almost makes it weaker.

[cybertech]

and the engine geometry of the 331 is better and closer to the 302

I love it here

my brother had 2.5" pipes on his 2001 v6 and he lost torque. You will lose it with 3" pipes

[Chris951]

I knew a guy with an 03 gt that put a 3 inch exhaust on. He dyno'd the car before and after he put it on. He lost a little torque and gained some horsepower from it

now what about me? sorry for stealing the thread but i have heads intake, cam, and a few other bolt ons... would 3" be overkill for me?
