Where to get original throttle body

[TALMADGE 1]

After removing and cleaning the throttle body twice this year and needing to do it agian. I was just wanting to know where can I purchase the 47mm throttle body besides the dealership.
Would a 52mm throttle body work on my 1988 bone stock 350?

a 52 would work and work fine! it will give you alittle crisper throttle response but for extra HP that alone wouldn't do much.

Thanks for the info. One more question, is the 52mm a direct installation with the throttle linkage, tv cable and cruise control and what brand would you recommend. I just want to replace my high idle throttle body, with cleaning only lasting a couple of months.

there is a guy on ebay that sells them for about 270. silky smooth. my friend Rich (screen name here is rrubel) can give you the info. i am still using my 48 mm tb.

i am sure it is a direct replacement since he is using 48 mm castings and porting them out and pressing new bearings in them. everything should bolt right up. pm rrubel for some info on it.

make sure you tell the person you are buying from it's an 88! they changed something with them in 88.

Yup, that's the guy. Quality work all around. If you're not in a hurry, send him yours and he'll work on it. Otherwise, he probably will be able to send you an already-done unit that was someone else's core. I went with the sealed roller bearings. This thing is soooo smooth...
