I thought if you ran 440 pistons in a 400 you needed to cut valve notches into the pistons? Seems clearance would get mighty tight with that tall of a piston and no notches...?
Possibly, but lots of guys run the the flattop TRW's in 440's and 383's that are only slightly down in the hole (or zero deck with a light cut) and they seem to run fine?

I always figured the factory didn't put valve reliefs in the 440 6-pack pistons just for fun...?

exactly , a single plane intake is NOT the best intake for LOW END TORQUE ...
this build is all over the place ...
now I'll jump on the band wagon , you have to build a stroker

And what TRW/speedpro piston in a 440 would that be ? The only pistons available are either .020 in the hole , the 6pk piston and it has valve reliefs or the low compression pistons and the closet one to the deck is .100 in the hole ?????
as far as the 383 , the flattop is .015 in the hole , anything else is deeper or have a valve CANYON ...

Yeah that KB 383 piston is pretty much a canyon I thought the 440 piston came closer to the deck than .020.
At deck height spec the F-M 424 440 piston should be roughly .010 in the hole in a 400. I'm wondering could you get away with a flattop 0 deck piston in a 400 without valve reliefs with say a cam of about .500 lift?

I know single planes are not heavy torque makers, but would the engine really know the difference
if I added a 1 inch aluminum 4 hole spacer???
I have to use whats available and what I can get
cheap..

A stock 383 HP intake would probably be better than that Weiand (Team G?) single plane if you're worried about low end tq. Best bet would be a used rpm perf. Even an old torker or tm6 didn't do too bad down low in Hot Rod's b engine intake test.

It's a old school weiand 7511 and it looks similar to an eddy torker.

don't matter , adding a spacer is not going to restore your bottom end .

based on my own use of one on an 383HP in a street car and the Hot Rod test, stay away from the Holley Street Dominator intake for sure if you want low end grunt. Don't know anything about that old Weiand.

dynos don't lie. Don't know about the sb one, but the offy intakes in the b engine test were downright terrible in comparison to the best in class ones.

Those X-cellerator intakes are very poor performers. I have one. Tried it on my 383, and its sat on the bench every since. Any edelbrock will far out perform it.
