273 TRW Legal Piston

House of Darts · 04-07-2013, 12:47 PM

Does anyone have access to older NHRA piston list for 273 4BBL replacement piston. Came across a set of old TRW's and would like to use for a new stocker build. Thanks

NHRA does not remove listings for approved pistons. That's so that people using older aftermarket pistons that are no longer manufactured can continue to use them. If your pistons are not on the list, then you will have to go throught the process to get them apporved.
