Description

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 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!!

Edelbrock 61595 Complete Heads

(D-PORT 72cc Chamber): Flow Numbers as tested by Edelbrock's SuperFlo SF-1020 flow bench @ 28" H2O
Valve Lift	.100"	.200"	.300"	.400"	.500"	.600"	.700"
Intake	65	136	199	237	255	262	263
Exhaust	52	103	130	245	151	157	159

They feature optimized oil return passages for increased oil flow. These heads are available in three heart shaped combustion chamber sizes, 72cc and 87cc. The 72cc and 87cc chambers are fully CNC’d to provide a 9.5:1 compression ratio when used with flat-top pistons. The spark plug has been relocated closer to the exhaust valve for improved performance. These heads are cast with extra thick port walls and a compact port size, making them ideal for CNC and hand porting. Complete cylinder heads include guide plates, rocker studs and high quality valvetrain for direct bolt-on application.

Intake Option- Port Matched to Heads

7156 Performer RPM- Dual Plane with broader power curve. IN our experience this is the most versatile street/performance intake on the market. 7/8 taller than stock. (requires drop base for Shaker applications)

5056 Torker II- Single Plane with slightly more top end/peak hp. Slightly lower torque curve off idle. .250 taller than stock.

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 necessary.

Valley Pan & Distributor Gear

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

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