Tom 92 tbi
5 out of 5 stars review

Great product really wakes up a tbi 350

I dont under stand the negative reviews this manifold has received. All the bull about 700r4 tv cable not fitting and throttle cable bracket issues. I bought this manifold and put it on my 1993 c1500 350 tbi. I have a set of ported 083 tpi heads a jet chip shorty headers and true dual exhaust and a cam with 204/214 duration and .422/.444 lift. This manifold fit great with no issues throttle cable and 700r4 tv cable worked perfect with the supplied bracket that came in the box with the manifold on the very first drive right of the bat I could tell way more responsive than with stock intake and definitely more power thru the entire rom range pulls hard all the way to 6000 rpms. Really works good and wakes up a tbi 350

Get Edlebrock

Bought it a month ago. Had it on for a day, and been trying to sell it since. Would return if i didnt have to pay a shipping fee, but im in alaska. This thing is better off as a boat anchor
