Looks like the same dual-plane offy that I have. Other than needing the correct 4bbl carb and plate (looks to have the plate already), any needed vacuum/water jacket connections, and throttle linkage hookups, it bolts right on. I had used the stock throttle cable and made a bracket to hold it in the correct position for the carb. Shouldn't be too difficult after some head scratchin'.

If I remember correctly, they recommend a Holley 390 4bbl with this intake. When I had my offy on, all I had was a down-jetted holley 600. A bit overkill and needed smaller jets than I had. It ran like crap at lower rpms, but wanted to really move out once it had some rpms under it. With the proper carb, I'm sure it would be a fun n/a setup.
