Re: 250 build

As far as carb choice goes, i can recommend an Edelbrock 500cfm or 600cfm. The 500cfm AFB has worked great for me, more compact than a Holley which was useful in my engine bay and is easy to tune once you understand the operation. I reckon 500cfm would be a good choice for your build, however if you...

What octane fuel are you planning on running? Your dynamic compression will be fairly high with the 264/110 cam and 10.5:1 static compression, 8.6:1 - 8.8:1 depending on cam timing. The 274/110 cam will drop it slightly to 8.3:1 - 8.5:1
