Seth, I think this is a great way to do EFI. I'm assuming this is for a 200 or 250, but you could make the same case for a 300. I think I'd be inclined to use a 2bbl throttle body with a direct mount on the log. The center carb position is directly above the exhaust heat stove in the intake floor an...

Re: Is there a good forged alternative rod out there for a 2

Take a look at Scat H-Beam Connecting Rods 2-250-6000-2000. They're a bit wide on the big end, but that's a simple job to narrow them. Bush them for .912 pins or open the pistons for .927 Chevy pins.

The added length might make finding a piston to get the right deck height a bit easier.
