Breathing new life into the 318 in the Scamp!
I remember everyone from over there, including you. 360 advocates are like minded! haha...
Yeah, they come in a 725 as well, with all the same options (plated aluminum, hand polished aluminum and plastic.)
These are 625CFM wet. I don't know if they are comparable to a ThermoQuad in the same regards, because I don't know what the TQ was rated at, being a real-to-life-application, true air + fuel CFM test or just air, which rates at 8% higher. The secondary looks larger in a TQ, comparitively, but it's hard to know without actually testing them both with fuel, side by side, but this is plenty for what I'm doing. I think the bigger model would do nicely on a 360.
I checked the valves on the other heads and they are 1.60, so I think I'm going to get the heads tanked, get the seats cut and set the valves with three angles. The guides and stems look fine. I found a race shop that did some work for a friend who wants to charge me $225 for a 3 angle cut and seats cut, after tanking them, so I may take him up on it if I can't get some new 1.50 valves for cheap. We'll see what happens.
It looked like it hadn't seen the light of day in decades, when I got it. -
After I took everything off of it, I cleaned the port surfaces up for gasket install and masked them off, then I media blasted the manifold, inside and out, over the lettering and everything, then I followed up with a mini DA sander over the lettering with 320 paper, then 500 paper, then I hand sanded it with 800 and again with 1500 wet, then I took rouge to a flannel cloth on it to polish the lettering.
After that, I painted it, then after I let the paint tac dry for about an hour, I used paper towel with a very small amount of solivent on the corner, along with a q tip with the same and cleaned the lettering, then I waited until it was completely dry and did it again with a dry paper towel to remove the hazyness from the polished surface. I think I'm going to go over it with a little more polish on a nice microfiber towel to darken it up a little more.
