Re: Upgrading A 250 L-6
Congrats on your new car. I've had several '60s vintage GM cars with 250s and had a lot of fun with them.
To my knowledge, you can't put a 292 crank in a 250 block. The stroke is just waaaaay too long. The 194-215-230-250 are sister engines, but the 292 is just a cousin. I had a 250 in my 66 C10 with a Holley 390, headers, and a hotter cam. It made good power, especially when the secondaries opened-up. Be prepared to do a lot of carb tuning, because most carbs are not close to dialed in to a straight six when you start out.
