[QUOTE="westgl, post: 97439, member: 2025"] The tubing i bought today is 1-5/8" OD x 1-3/8" ID, ID is actually 1.380ID so .005 over 1-3/8"id, big deal, that difference wont be felt. I have some clamps from Napa that fit the OEM manifolds, I think they clamp better, than stock. I looked at the rubber on the OEM manifold after they were clamped, I noticed that the oem clamps for the oem manifolds do Not clamp in a circle and distort while clamping. I think i will get a better seal if i use a better clamp. When clamped the rubber on the manifold has a almond shape, instead of round. The clamps i have are narrow like the oem clamps, but are SS, and have more adjustment, to close further, so they should provide a decent seal. Tomorrow, with any luck, the fun begins. I will start cutting material to size. Then start marking, and measuring, for holes I have some high temp solder 1100 degrees melting point, more than what I need, will not melt, even if hot coolant was heating the plenum floor, & 20,000 psi tensile strength, so it should hold up well. I have asked my self, should I seal the two Plenum halves together with the solder. How many tries, will i need, till i get it right? Would i need to disassemble it? a torch could get it apart, the solder would be just a seal. The Ultra Black should provide all the seal i need. I have used Ultra black many times, I have headers on my 67 chevy Truck, No header gasket, header manufacturer says use Ultra Black Silly, for seal. [/QUOTE]
