I have a 63mm TB on my 350ci,but have not done before /after.
I will just give/add some thought.

If you port/increase air volume by 10-15% on stock plenum,IH's or even heads i would think you wanna do same with TB.
It doesn't hurt and could be worth power.

Also for the price consider it one of the cheaper mods.

$300 for 3-5hp i'll take $900 worth of HP please

Thanks Pete. Who the heck is gonna argue with the times you have on your 350? At least I know the said builders are straight up guys and not trying to just get $ or it would have been encouraged and not discouraged. I was kind of given the impression that I would be wasting my $, but as you stated it surely could not hurt. I can see it as a waste of money if someone has stock porting on plenum, IHs and heads.

Not anymore. I did have idle problems with it though. Marc H looked it over twice after the intial 63mm'ing. The last time he seemed pretty confident it would fix it, as he'd mentioned he'd learned some things. And he was right. It actually seals quite well, to where it has IAC counts in the 20's even after it is warmed up. I've thought about adjusting the idle screw to bring the counts down, except I hate to mess with things that are working.
