Looks nice.

I have a similar SB EFI TR setup I'm also wrapping up. Two questions, it looks like your fuel enters in the rear on one rail and returns on the other? I set-up mine to enter on rear, and returns on front, on opposite corner, just seemed best for fuel temp and any pressure drop, that also means I connect both rails together, front and rear.

Second, I also have a upward curved crossover in front, I wanted to trap a pressurized air pocket to dampen any injector fuel pulsing. Not sure it indeed will trap an air pocket. Was this also your intention?

Were did you located your air temp sensor?

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
