I'm not necessarily against using a larger throttle body, but it may not be necessary to use a larger throttle body, and it may actually have a negative effect on performance. Unless you are doing a fairly radical 95" build, high lift cam and oversize valves, a larger throttle body will not compliment your build plan. Higher intake velocity makes more power, bolt on a larger throttle body and you lose velocity. If you are going radical, then by all means use the larger throttle body, but if your doing a mild build with a bolt in cam, and maybe light port work on the heads, I wouldn't use a larger throttle body.

+1, with a mild to mid rage 95 build that is going to remain streetable you could use the $ for other things than a Throttle Body, it wont improve your performance. The stock Throttle Body will easily support a Stage 2 - 95 kit (ac, exhaust, cams) or a Stage 3 - 95 kit (ac, pipes, cams, head work)

I don't know the specs for the 95" SE motor your parts are coming from, and I'm not about to speculate what the blue print looks like. If you keep asking, someone will chime in and give you the answer you're fishing for and permission to use the 50mm TB. I over cammed and over ported the first motor I ever built, it was an expensive and frustrating lesson, I guess you will have to learn the hard way also. Good luck.

It may not produce a negative result, IMO its just not needed to get the performance out of a basic 95 Stage 2 or 3 motor. There could be better ways to spend your $.
If you have not built a HD motor its really important to have a soild plan before starting or you may waste a lot of $ on do overs or not get good results by combining the wrong cams, pipes, heads etc

head work can change everything,the rest of the build should be designed to compliment the head work and commpression.the whole package has to work together,u can get very good results using relativly mild parts.
