This is a bad case of thread hopping! I am there with you in putting a blower on - I think a blow through 4500 carb will just be too tall on my B block 499 cause if the size of the 4500 hat (I have a 4500 E85 carb and the hat - huge).
Soooo, I can adapt a 4150. need a throttle body. The 4150 1200HP system looked about right but now you say not enough flow for E85. Isn't the 1200HP system supposed to have 8 injectors? Are they in the carb or do they mount on the intake?
So if that system doesn't cut it, what about using a Holley like this and sizing the injectors to the power/fuel?

That would require adding injector ports to the intake which is how I need to go as my intake is matched to the B1 head ports. In a way I am lucky to have Monte Smith nearby cause he is a big Holley FI tech but he wouldn't do FI on my hotrod unless I let him replace all of the orig wiring - no go.
Another way I have considered is to use a 90* 4500 flange throttle body elbow and a 105MM TB, with the 8 injectors added to my manifold. Then use some EFI system like holley or ?
