Going old school this week building new 83'-85' 200x kits to run on pump gas with all new cams to match. Wiseco 12:1 on the left with our modified 11.5:1 one in the middle with improved flame travel to make it pump gas friendly, and Wiseco's 10.25:1 on the right. A new cam is coming soon to give you max power with the new 11.5:1 piston to run on pump gas.
