1965 426 wedge
A question for you guys, the NHRA specks for the 426 wedge is max bore of 4.33, the standard bore on a 440 is 4.32. NHRA shows the pistons allowed for the 426 but Im wondering if I can use a 440 block and the standard bore piston with NHRA excepted numbers. I hope I explained this right. Maybe call the tech people but I have no phone number. Thanks
