L98 Intake vs LT1
I was wondering if it is possible to swap the L98 intake onto the LT1 or LT4, and what would the pros and cons of doing that be. Looking for low end torque, the L98 intake looks better for that, but is it?

The ports match, the china wall will seal. I believe the water passages may be different.
I assume you are plugging the hole for the standard distributor and keeping the Opti. Your current throttle body should bolt right in. However, I'm not sure about the brackets for the cables and whether they would be at a really odd angle, since the TPI is taller.
I hope you pull this off.

Mini ram. Edelbrock pro-flo xt will work with some mods to tb flange. different torque curve. LT1 doesn't have distributer

Not going to happen, if you want to increase the low end grunt feel, change the rear gearing. It'll rev into the power band quicker and will feel faster off the line. Similarly you can change the TC (if automatic) to a 2400 stall.

I hope the OP goes through with this.

Itll probably be a few years but my plan is to actually use an L98 instead of swapping the intake. I want to put it in an off-road vehicle so it needs the low end torque.

Just to be fair, there was (is) a rare version of the L98's long tube intake that was made for the LT1 engine. (Don't have stats on how many were made. Or, I think, rare FFI long tube intakes. But maybe they never actually made -- tho planned -- the later).
