Default Difference in rotated 30r sizes (both .60 comp/ .82 hotside)

just wondering what differences these 2 sized 30r's would make

old perrin kit came with 2.5" hotside (only necks down to this for 3/4"-1") and there is a t4 style flange on the up-pipe

all newer kits look like they came w/ 3" hotside and t3 style up-piped flange

wondering cuz with the first combo of parts I still put out rediculously good power, so it must have been a good combo with the huge up-pipe let out

just for info, the pump map is our 91 octane out here in CA on 23psi (pretty much never used this map)
race was on c-16/ 27psi (used this only a few times)

99% of the time it was on 19-21psi/340-365whp on pump and the few times I used race gas it was on 24psi/425whp half those times
