Butler Performance Top End Kits

Complete top end kit with almost everything you need to upgrade your normal Pontiac to a Butler High Performace Pontiac. These high HP combinations have been used in Butler Performance builds for many years and have powered some of the highest performing Pontiac engines in the world. We now offer these kits to take the guesswork out of piecing together a good combination that works well together. All these kits are actual build kits used in our shops. If its on here we use it in our own shop!!

Pushrods & Pushrod Checker

We include a pushrod length checking tool in each kit for measuring proper pushrod length. Because brands of lifters and rockers require different pushrod length.

Rockers

We offer many style rockers to choose from. Rockers that will work for these kits include stainless steel or aluminum from brands such as Comp, Scorpion, PRW, Crower, and more.

We recommend 1.5 ratio rockers so that pushrod slotting is not neccessary.

Valley Pan & Distributor Gear

Hydraulic Roller Lifters require aftermarket valley pan such as the TPP-TP-041S

Requires polymer distibutor gear such as BOP-PDG37 or BOP-PDG38
