<p>Jay, thanks a ton -- the manifold arrived today, and once I can dig a tunnel through the snow to the Winne, I will get it running. But I owe you, man. That was fast shipping!</p>

Hehe, had a funny thought Rich, an excellent retort for the old cliche. "Hey woman, you aint the only one who slaves over a hot stove all day!"

<p>Your right David they can be brazed and successfully. when I weld cast I drill a hole on each end of the crack to stop it from spreading some people go a step farther and drill and tap a hole for a set screw on each end. I then grind the crack to make a v shaped groove for the filler rod( a high nickel rod works best ) also known as nirod. I then preheat the piece and weld it by skip or stitch welding, middle, end,other end then start fill in the spaces until the whole crack is filled…</p>

I then preheat the piece and weld it by skip or stitch welding, middle, end,other end then start fill in the spaces until the whole crack is filled keeping the piece hot at all times. the last step is to bank the piece in sand or other material as to let it cool slowly. I've welded manifolds, engine blocks and pulley's this way with good success but have had my share of oh craps as well. It sounds like a big deal but it really isn't that bad. A new one would be the best but in case you can't find one this is the next best thing other other than headers.</p> I made a jig and welded one o…tag:goodoldrvs.ning.com,2015-01-30:2093474:Comment:2452212015-01-30T01:42:26.425Zdavid crafthttps://goodoldrvs.ning.com/profile/davidcraft
I made a jig and welded one one time...your supposed to preheat the cast first? And then weld...its a tricky process. Dont just get the rod and try it. Get a professional. I dont know that brazing might be better. Best would be another manifold. I got one before and the ears were warped a little. I put her in the bench vise and ground her flat before mounting. Got a good seal....good luck

<p>Welding cast is doable and can be reliable if done correctly, If you have a good welder available I would go for it. One thing you will want to check after the welding is done is the make sure the mating surface is still flat heat can warp the manifold and you can crack it when you install it if there's a bow in the flange. good luck with your project. </p>

<p>Not exactly all that cheap, are they? That outfit is mighty proud of it's products!</p>

<p>These are the type I have on my 360, along with a free-flow 3" single exhaust. I had to add a resonator because of the hot-roddy rumble, but it's still a bit on the "look at me" side at idle for my taste.

The prev owner had removed the original twin tailpipe/single exhaust pipe setup and installed a really hokey dual exhaust setup with glasspacks. The tailpipe on the passengers side exited close to the coach door and exhaust fumes and noise were a big problem. There was no equalizer crossover pipe between the right and left banks, and therefore no scavenging effect from the V-8 firing order. Lousy power, poor MPG, fumes and it sounded like there were two 4 cylinder engines. Perfect!</p> Dang Matt, you're the man.

<p>Dang Matt, you're the man. I've narrowed it down to 79036 or <a href="http://www.summitracing.com/parts/hed-79030" target="_blank">79030</a>. I have to do a little more research. I'm hoping it's the cheaper of the two...</p>
