i have found almost every way to squeeze as much power out of my 351w with bolt ons, but i was wondering what kind of gains a throttle body spacer would get me, any gains or loses?

From what I've read...they aren't worth the coin or time.

Not worth the price at all.. I put flowmaster exaust, K&N kit and MSD coil and then the spacer. I noticed the bigest difference with the K&N. The spacer is crap. I only keep it on because I am too lazy to remove it and sell it to the next sucker on Ebay

Haha.... think about what a throttle body spacer is... and what it could possibly do, other then beat you for 120 bucks.

throttle body spacers are junk as well are intake spacers.. the only ones ive seen that help hp wise are for racing hvh( high velocity heads) super sucker i believe is called for carbed motors.. if ur lookin for more power look on ebay for a 408 rotating assembly..

(off-topic)
id like to find a newer supercharged lightening thats been totalled so i could try and swap that into the 87 bronco.. that would be really sweet

make a throttle body spacer yourself for free, go buy one from VIP or something, take down the dimensions and make it out of alluminum, then return the one you bought... the hardest part should be the 2 helix's to spin the air... besides that its straight forward

Better yet, give me half your money now, I'll take you out back and kick you in the nuts, and we"ll just call it a day!

There's your best bet.

Still wouldn't do anything useful. :thumbup

A throttle body spacer is absolutly useless.

If you mean a phenolic spacer then I disagree.
Phenolic spacers lengthen the runner wich increases velocity wich increases torque. They can also help reduce upper intake temps (especialy with no EGR)
Hp gains are unimportant.
