Lenard? not sure which Otto brother it is?

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

Most of what I have seen is 4inch bore and bigger, roller cam and vacuum pump

cheers Richie

. On 4" bore most only may have 78 stroke . And I like the flat Tappert cams more to run lightweight lifters😀
