Most peeps say however that an additonal 3/8" is needed on top of the flip and use a header collector flange to do it. anyone know the size of those flange's?
with a strut flip, you need something to compensate for the "lip" the stock strut mount has. I've used washers, I think an flange is a better solution (but my stacked washers never let me down either).
As to size? ... I *think* a stock SBC flange is what ya need, but easiest is to pull one of the strut tower strut mounts, go to a NAPA and have them find the one that fits.
I plan to drop into an exaust shop and see if I can figure them out, and maybe still use 2 each strut and some 3/4" spacer pipe welded together to make a 1.5" spacer. If I need to add the 3/8" to the flip I might as well go that last bit and make the spacers!
if ya can fab the spacers yourself, I'd say do it.
I expect that an exhaust shop tho will give ya bunches of blank stares.
Turns out my clutch is also going, damn. Anyone ever used the Rhino Pac clutches? I think unless someone says they are dung thats the way I will go.
I can;t comment on which clutch ya should get ... there are good aftermarket clutches (centerforce and I think petrowerks has a good one too).
But, if you're going to be dropping the tranny ... go ahead and do tcase gears too. It's spendy ($650 from trailtough), but is by far the best $$$ you will spend when you put it into 4lo. (it's an easy install if you're careful).
