70mm TB going to help me?

i am going to go ahead a grab a 70 mm TB this christmas.

my combo now is
thumper e7s
tmoss lower with home portmatched upper.
B-cam advanced 4 degress with 1.7s
UD pullies.
CAI
73mm vortech (C&L) MAF
bbk unequal shorties
H-pipe and dynomax race bullets.

the tb is the only real engine bolt on i have left to do, then all i really have to do is forced induction which i dont currently have the funds for. so i am going to start some suspension work with SFCs and upper/lower control arms for the rear.

but anways, people say bigger TBs dont help at all on stock engines, but my combo isnt exactly stock so i am wondering if i should expect to notice a pick up in power. I was thinking it should go hand in hand with the 73mm MAF i have. i put that on a didnt notice a thing, which seems right bc the engine was still sucking thru the 58mm stock TB. so i am hoping i should noticed a decent gain or at least feel that the engine is breathing better.

what do u think.

thats what i figured, why waste the money on something only 7mm bigger, thats not much. i would rather have the bigger one that i can grow into and not have to trash it.

havent really ran it good.

i took it once with the new engine and it ran the same as b4 (low 14). i never did any tuning, timing and FP was off alot and it ran bad. i got the FP and timing dialed in and its running like a raped ape. i plan to toss a TB on, SFCs, and some rear controls and at least tackle low 13s, maybe high 12s.

just gotta see what happens.
