well, order arrived from Summit today, my Motorvation TB intake spacer, not sure if it will make any difference, but worth a try, they claim more effieciency and a tad more power, as they all do

and my EFI rocker covers, to go with the cobra intake, just hope my roller rockers will fit under them

I'd love to know how the spacer performs between dyno runs.

only dyno I get near is the stretch of road between home and work

I think you'll find your oil filler in these Mustang covers won't clear your intake, even with a spacer. Normally an EFI truck intake is required with the filler on the front passenger side cover.

it clear sas in it won't hit, but will be a challenge getting oil into it, I'd already thought of that, and if it all goes pear shaped I'll just put it on the passenger side with the filler at the rear, and if that fails, I'll sell them, no biggy.

spacer is in, doing a drive test tommorrow, although it will be false as I busted a silicon joiner on my steel intake so had to put the stock turd back on.

I'm a bit concerned about the I.D, putting the vernier across the I.D I get 59mm, I have a 65mm AU TB fitted and the manifold was honed to 70mm by the previous owner, when I measure the I.D between the spirals I get 68mm give or take, was hard to measure, have I introduced a restricition after my TB or will the fact the spiral start points line up with the I.D of the TB actually help, and will I introduce turbulance again with the step to teh manifold, my fluid dynamics a waaay rusty.

don't think I'll notice much, but I'm after economy with the bonus H.P
