Frank Storms 06-10-2005, 08:40 PM What would be the advantage or posible disatvantage of a custom made billet 64mm throtle body over boring out the stock one to 58 or 61. It would be on a 1550 bigbore. Is it possible to just go to big on the throtle body.

Also if you ever want to run in the AHDA you will not be able to use this TB other wise it looks good. Find a real good tuner that can work with the timing also and you should be able to play in the higher rpms Rick Nielson 06-11-2005, 02:27 AM What would be the advantage or posible disatvantage of a custom made billet 64mm throtle body over boring out the stock one to 58 or 61.

Rick, It is not a matter of trusting my engine builder. I certainly trust Paul. He really knows his sh_t. These are new to him and he will be doing some testing on them shortly. I just wanted to see what others like yourself thought about this mod.
