Well like it says above. Im looking for a peformance chip for my 85 tpi 305 iroc w/auto. If you have one please let me know what you want for it shipped and the brand of course.
Would also love to find a 52mm throttle body rebuilt/bbk/holly dont really car which but the cheaper the better doesnt have to be show quatitly just needs to work.

 

Personally, I wouldn't go with a 52mm TB on that 305.
I would go with 3.45 or 3.77 gears first, as you won't gain anything with the TB.
Gears on the other hand will be instantly noticable.

 

Well just so people dont cheap saying the above which i keep getting told, I do know that. I will not change the rear in my car as its a daily driver and gets really good gas milage. then 52mm TB is for a 87 383 stroker motor i built and just looking for the final parts before i use it. thanks though
Brian
