Quickest ever with my Valiant

Oh yeah. Really ate number 3 piston. Melted aluminum in the cylinder, combustion chamber, and exhaust port. Also warped the valve.
Put together another 170 block I had in the pile. Standard bore, new stock cast pistons, moly rings. Pulled a crank, from another engine, that was .010 and.010, in good condition. Installed a used Racer Brown SS-14 cam (268 dur, .466 lift). Can't use too big a cam (no valve reliefs, 170 is zero deck motor, but this one is .040).
Had another head in my stash that has 39 cc chambers, but stock valves, that just needed washing. Will install the head, today. I will still have to check the nitrous system, to see what went wrong. Hope to remove the old engine, and get the new one in, by the weekend.
This motor will not be as fast, but at least I'll be able to race.
