boy that TB looks just like a LT1 TB. not a L98 TB. i used my 86 TA factory TB and the holley 52mm TB with no issues other than the TPS lever on the holley needed minor grinding on to clear the plenum.

 

I tried it out on my HSR that is sitting on the shelf and I found that I needed to grind the thing too. I am using the Accel 58mm TB. I think it is all about the shape of the wheel the cable goes into. If mine was a little more rounded it would have worked. I would bet that if I were to buy the Holley 58mm TB it would have worked too.

 

Hey Aklim, were you able to figure out the throttle cable length problem yet?

 

You mean besides taking the throttle stop out or bending it to fit? No. At least, not if you want to keep the stock length cable without going with an aftermarket one that will be adjustable.

 

Yeah, I just took that throttle stop bracket out by the pedal. Not too sure if that was the bst fix or not, but it's working so far...
