My TFS 215's were opened up to 4 inch bore for my 402 and make huge power! I have to echo everyone else saying get the 3.9 standard bore TFS 215's. Give Ron@VengeanceRacing a call for a very fair price. (Authorized Dealer) I believe he price matches too. Just for reference, I gained 28.xx rwhp on my 402 just by going to the TFS 215's (optimized for the 402) from the AFR 205's that weren't optimized, both milled but the tfs had a 4" bore vs the afr 3.9" bore. Similar power down low, but from 4000 rpms to the rev limiter it feels like you are spraying a 50 shot !!!
