Pretty sure they use East coast Pro stock rules, and its 9lbs/CI with minimum weight of 1300lbs for stock head stud pattern and 1350lbs for non stock head stud pattern[WBX/Autocraft/ pauter etc 4inch bore & bigger] Found this link might help you http://ecpra.com/WP/pro-stock-rules/ Most of what I have seen is 4inch bore and bigger, roller cam and vacuum pump cheers Richie Title: Re: Engine Combo in Pro stock Post by: ottobros on September 18, 2016, 15:27:39 pm Thanks Richie for the info

And I like the flat Tappert cams more to run lightweight lifters😀Pretty sure they use East coast Pro stock rules, and its 9lbs/CI with minimum weight of 1300lbs for stock head stud pattern and 1350lbs for non stock head stud pattern[WBX/Autocraft/ pauter etc 4inch bore & bigger] Found this link might help you http://ecpra.com/WP/pro-stock-rules/ Most of what I have seen is 4inch bore and bigger, roller cam and vacuum pump cheers Richie |
