Well, I have had these sitting in my garage for a while, wondering how they might work with my 383 buildup, the answer was not at all, especially when it necks down to 2 1/4 inches or less at the collector, so I was just going to get longtubes.. but looking at the board I figured why not get some Jegs stainless collectors and have my local weld shop weld them on and see how they work.. 70 bucks later, viola! 3inch collectors on the 1 3/4 inch shorty..Thought I would share this, they will go 3inches back to a 4inch mufflex after test fitting and the black jet-hot treatment.

 

whooo ther ebuddy ,383 build up ,WTF you didn't ask for my permission for that ..lol drop me some details ,i think i'm fixing to sell this caprice and either get a monte SS or a third gen ..

 

Yep, big efi supervic LTx project in progress, along with a teardown of the car again.. Selling parts to get other parts etc..

 

nice job. that's the way they should have been built.

 

thx,
Hopefully they don't pinch the horsepower too much now, I don't mind a bit of horsepower/torque lost down low so long as I can keep most of it up top.. we'll see when it all hits the dyno.

 

Do you have anymore pics of this? This exactly what I am planning on doing. I ordered the spohn k member for more clearance.

 

Seeing as this post was revived I will state that is one of the problems with the SLP headers. The collector is too small and the steering clearance is minimal at best. Thats why I went with the custom 1 3/4" header by Dyno Don. Not that the other headers are any better. IMHO the Edelbrock is low on my list.

 

Thats a good point, I know there is problems with the driver side header and the steering shaft, does the shaft rub against a pipe or the collector?
