Re: horse power

Search the IFS board for all the opinions/info on throttle body spacers. Also search for TBI Upgrades or TBI Performance.

Re: horse power

I put a spacer on my 89 a couple of years back and it seems that it made a little bit more power, especially at low RPM.
Whatever you do, do not buy the Pacesetter Air F/X intake for your truck. It is a POS and you will be sorry you wasted your money. I bought one and ended up ditching it in a month.

Re: horse power

if you intake is set up the way i think it is, it runs from the cleaner to the fender in the order 1. element housing 2. flex tubing 3. air canister 4. fender what i did to my 89 when i had it was replace the canister with a section of 4" pipe (abs or pvc) and a fernco fitting and a couple of hose clamps. This got me from the fender to the element housing in one staright shot. for the filter just get a k&n and be happy [img]/ubbthreads/images/graemlins/smile.gif[/img]

My dad also put a TBS on his 93 and as you said it seems to make a little bit more power. I felt some more low end torque.

Re: horse power

Isnt an 87 the old body style, making it a carbed 350? I may be WAY off on this, not really a Chevy engine buff.

Re: horse power

I just run an open air element on my '93 and love it. I got a bit more power all around. If you go open, buy an air cleaner housing for a Ford 2 bbl carb, fits perfect.
