I love that intake port. really outstanding.
The intake valve, about what size were you able to get it at from 49mm? And were the seats changed or just cut as wide as possible to fit the altered 49mm intake valve?
Will you be using a V94 or equivalent space cam in the MFI pump?
That port size will actually be streetable with something like a DC60 cam, so don't think you can't street this rig one day. The only motor of this type of build I've driven before (which actually inspired me to build one myself) had 41mm intake ports with about a DC60 equivalent cam and was quite tame, but it revved to kingdom come
I'm guessing you're shooting for around 300bhp+ at the crank, and from what I'm seeing that looks entirely possible. Great build. I'm actually doing an identical build but am not as far along as you are!
