WOW! 1969 YK block with 4 bolt main, 390 HP from the factory with 16 heads that had the 2.11/1.77 valves......................at least that's what I'd hoped to find.
2 1/2 hour drive. YE block 2 bolt mains and 1969 47 heads, which according to 3 different websites came on a 350 engine rated at 290 HP.
5 friggin hours of driving for that. He wanted 600. The block and heads were clean, not what I was looking for.
