Drop a 35mm gauge ball straight thru the port they call this 36mm dropping a 36mm gauge ball straight thru they call this 37mm.
I also have a 36.5mm gauge ball.

Your question about the power level.
You can't get the intake big enough for it to hurt driveability of course alot is also in the tuning.
My lil 350 intake was more or less what they would call 38mm no divider in the plenum with no secondaries made 330 rwtq @ 3k rpm 410 peak car would run 11.0's @128-129 mph ran 154mph 1/2 mile.
Car drove like a stocker would drive it to BG,car shows etc,
My ports are 38mm+- but went into oil same port on 1 on each IH i do not reccommend this for the faint lol

Like i mention its also in the tune.
Hope this helps you with your venture.

There are a few 350 ZR-1's running around with ported top ends to 37mm some with stock cams some with performance cams
That make good HP/TQ #'s they might come on here and reply on the driveabilty.

I have done hours and hours and lots of $$$$ research on cams on the LT5.
If going with performance cams gotta pick the right set of cams price is irrelevent in this case you get what you pay for.
