674 Tq & 650 Ponies of Pontiac Power! Built by Butler Performance

Ed started this Build using an IAII cast block that he will be using for street/strip/pro touring. To achieve this while still making this a great engine for cruising we used Edelbrock 87cc heads that we ported to 325 CFM along with a Northwind 4150 intake that is portmatched to the heads. Tucked under the PTF dropbase is a Holley Ultra XP 950 CFM carb to provide the needed Air/Fuel Flow this engine requires to make Ed's 77' Trans Am perform at its peak no matter where and when. Butler Performance polished valve covers really make this engine bewilder the beholder with a mirror finish. Sporting a Butler/Comp Hydraulic roller cam with a 113 Lobe separation helps add more pep especially paired with Eagle specialty products 4.250" stroke crank and the Butler/Ross 4.350" bore Dish pistons. Along with the Butler Performance GZ evac kit this engine is setup to be competitive at any pro touring event. On the dyno this engine produced 674 torque and 650 Horsepower which is a perfect balance for getting the head start and making sure you keep it.

Just checking in after a year has gone by and I love my engine more than ever! It's more awesome than I could have imagined and I so look forward to spring where my 1977 Trans Am can be on the road again! This engine is amazing, doesn't overheat, runs smooth on the street and has great manners, but when you lay down on the throttle, she will lay down a 30 ft plus burnout without a moments hesitation. When I pull into a car show, especially a Pontiac one, heads turn as they hear the sound this engine makes. Botton line, you can't go wrong on dealing with Butler and it's the best decision I ever made when building my project TA. Butler is the best, hands down!!!

Must be a 535 or 541? This engine really gets the job done. Would love to see a video of the car once this engine is installed.
