L98 vs LT! Throttle Bodies?
Just reading in this month's HPP that Holley makes an LT1 throttle body with integrated nitrous ports for a total sleeper installation. Are the throttle bodies similar enough to be swappable? Does anyone make this for the L98 throttle body?

I think the throttle body is the same, or similar, but the linkage is different which makes it unusable. Contact Holley and see if they make one, or will make one for you. If there's enough interest they will.

I dont know about the Holley TB, but I was able to modify a AS@M LT1 TB to make it work on my L98. Basically I took the stock bracket where the cables hook up, and stuck it on the LT1 piece. The other differences I think was a missing vacuum port for the EGR. Sorry it has been a few years since I fabbed mine up,and cant remember the details, but it wasnt that hard to do.
