I remember racing against a 348 tri power 58 chevy. I had a 58 Chevy with the 270 hp rated dual quad 283 which was quicker than the 280 hp rated 348 because of the higher winding potential of the 283. Pontiac also used the tri power in 58 and for quite a few years but chevy switched to two four barrels. The 427 Vette had tri power in the mid to late 60s.

Hi, I don’t have anything to look up that casting # but I see that the last part of it is L6868. The 1967,68 & 69 Corvette’s had a 427 option called the L68 that was a tri carb. As for the firing order all SB and BB Chevrolet   automotive engines share the same.

I hope that helps,
