Throttle Body Compatibility?

I'm looking at TBI spacers, and when I search for an 89 camaro on an online parts store or in a store and all that comes up is for TPI. I noticed in my Summit Racing catalog that there are a lot of parts for a 5.0L 305 TBI engine under the "Truck/SUV" section. Is the 305 TBI in a chevy truck the same as the 305 TBI in my IROC? If so, then the TB spacer should fit, right?

Thanks,
- Justin

yes you have to purchase one for the truck, but your car is an IROC with a tbi engine stock?

Re: Throttle Body Compatibility?

Thanks droptop, that really took some weight off me. I've been trying to get that question answered for a long time. Hood clearence won't be an issue for me, I've got a lower than stock air cleaner, and the hood pad is off, so yeah, it will get a little tighter, but nothing to worry about though.

Thanks for the input.
