cshar5 –
Tried to use this on a C1500 LS conversion. Part is very nice out of the package and definitely well made. I couldn’t use the part mainly because I am running a stock GM throttle cable and the use of this part requires a different throttle cable. The second issue is that Holley could have made the mounting flange a little larger for stock intakes because it BARELY covered the o-ring gasket between the throttle body and this part. I’m sure it works fine but it just didn’t fit my application like I had hoped and is now sitting on my shelf.
LS stuff –
Worked for what I needed. Made nice would look good if not all dinged up and scratched.
