Are you going to get the FWD LIM/UIM?
There'* lots of question marks to figure out. Yes, If I did this I would use the FWD manifolds and TB. There'* nothing to gain by using the RWD manifold and it introduces too many problems. FWD manifolds are easy to come by (local price is $60 with injectors, rail, TB, etc)

This is sortta the backup plan should the LN3 die a quick death with a M62 tacked on top. That project is really gaining steam as more of the "must do" checklist is completed. Only thing left is trying out the double-row balancer, getting a chip burned, locating a few hoses for the power steering, and doing the actual swap. Wife is being pretty cool about this as the assemblies are being staged in the living room. The entire manifold/blower/TB/air cleaner assembly is sitting on the fireplace (at least it is clean )

Course, if the LN3 doesn't puke it'* guts out the bottom end, then the whole topic becomes a moot point (at which point I'd say "Anybody wanna buy an L36?"

Do you know how different these are?? The runner lengths, shape, and plenum volume are all different. I have a hard time just throwing all that aside and saying theres nothing to look into or possibly be gained one way or the other.

Well, I don't see anything different in the power output of the FWD vs RWD L36. Both rated at 200 to 205hp @5200 rpm. So, I stand by my statement that there'* nothing to be gained by trying to work with the RWD manifold in a FWD application when there'* an equivelant FWD manifold already available.

If you want to play with it, it'* yours for the cost of shipping.

Just a follow up on this topic. The L36 is still sitting on the engine stand. Insides of the motor look pretty good. Tomorrow I'm picking up the FWD bits from a yard in St. Augustine to reassemble the motor as an FWD L36 (entire induction, exhaust system, front cover, and accessory brackets.)

Another fun little project for the labor day weekend...though it'* #5 on the project list...so it may have to wait a little longer (not really a big priority as it'* just going to get wrapped up in plastic and tucked into the back corner of the garage for a rainy day.)

Cost. Motor is a backup should I grenade the LN3 with a blower. If all goes well, I'll never have to install it and will sell it off later. At this point it'* a $300 insurance policy.
