Offy SB intake…. Any good??

i love how these always devolve into esoteric debates about fluid dynamics, the arguments of cross sectional area and taper of runners and modifications of the center divider in order to gain that one-tenth of a second and half a mile an hour in a race.

the dude wants something fun to go out and do burnouts in and maybe take the track.

this will easily accomplish that.

it may not have good street manners, it may not have great racing numbers, it might not even be the best fit for what camshaft he has. but it's going on top of a 340 with a 4spd and 3.90's so who cares about good manners and numbers at the strip-- snap a double pumper on there, side step the clutch and listen to the roar of the motor while you annihilate a set of rear meats and grin from ear to ear.
Very easily and totally unmodified. I'd not even modify the divider. In any way shape form or fashion. Unless you have a flow bench in your pocket, you don't know what you've done has helped, or destroyed a perfectly good intake manifold. I would clean that thing up, do any necessary repairs like bolt holes and run the snot out of it.
