1965 Impala BBC Stocker Update

[Greg Reimer 7376]

I remember reading about the 396 375 horse 4 bolt main block being "dual purpose,"that meant, 396 or 427. It had some massively thick walls, in one case, one was bored out to 4.3150 and used a standard 409 ring. Imagine a 440 inch 396 coming at you! The later block I have was a 70 402. It had 290 small plug heads, the flat intake, and a cast crank.
