Bullnose 408 Stroker MPFI intake recommendations
I have a 1985 short-bed single-cab F150 that originally came with a 351W, but had no motor when I bought it. I bought a 351 bare block and had it bored and stroked to 408.
My plan:
AFR Enforcer 185cc heads
Holley Terminator X Max
DBW GM TB
Replacing the entire fuel system to complement the Terminator.
I'm having a hard time figuring out an intake.
At first, I looked at the Holley Hi Ram, but I don't think there's any way that'll fit without adding a hood scoop (which I don't want to do)
Then I was looking at the Edelbrock Super Victor, but comparing it to the Air Gap RPM, it seems the Air Gap would be better for the low end (I'm not racing).
But I'm concerned about hood clearance even with the Air Gap. Would a drop filter be low enough to clear since it would be sitting on a Holley 4150 adapter rather than on top of a carb?
Am I going to have to do a body lift no matter what to make anything I add fit?
The engine is not in the truck, so I can't measure clearance. Should I just wait until I get to that point and measure clearance before I settling on an intake?

I would stick with the dual plane intake for low end grunt. Since you said something about a body lift, I am assuming this is 4x4 and you are going run oversize tires on it. Since you stroked the engine, I would keep the camshaft mild for even more low end power, and watch out for your final gear ratio. If you are going to run large tires, you might want to think about 4.10 gears in it.

main pain point right now is if I have enough clearance for the hood. That’s why the body lift question

These trucks have a lot of room under the hood. I do not see why any of those intakes with the throttle body would not fit.

That high ram/tunnel ram intake looks interesting and it will probably have a longer runner length than the Victor style single plane which will put it more in tune at lower speeds. The dual plane idea is also cool because dual planes can resonate sort of like an intake that has runners that are as long as the length of all the runners on each plane added together.
