I am the proud owner of a new 52mm throttle body.[sm=happy046.gif] I am wondering if I have to change fuel injectors. Also remember I have ported and polished heads.

Anyone out there have one installed on their truck?

 

yes i have a fastman re-worked to 52mm im using rt heads port matched and polished with the 3-angle valve job ,i had them run bee-hive springs(which taper at the top)so i could clear aluminum roller rockers,with NASCAR push rods,plus a cam and ect but as to your question ,,,,I LOVE IT,the sound improved with the bigger valves and on the interstate it kills
