Here at Golen Engine we offer full line of High Performance LSx Engine Builds using all American Made components from trusted brands such as GM, Callies, Mahle and Comp Cams just to name a few. Owner Chad Golen officially started Golen Engine in 1992 in Lowell, Mass as a small two-man shop primarily building Small Block Chevy Performance engines. With the help of his father he purchased a full machine shop in Hanscom AFB in Bedford, Mass in 1998 and quickly incorporated under the name Golen Performance Group. The new Shop at Hanscom AFB featured two crankshaft grinders and all brand new lineup of Sunnen equipment such as a CV-616 Cylinder hone, rod hone, and resurfacing equipment. This shop allowed them to control the quality of the machine work and assembly to ensure a better overall product. In 2002 they purchased a 12,000 square foot shop on 6 acres of land that they still reside in today. This allowed them to set up the shop for a smooth workflow and made room for two brand new Super Flow SF-902 engine dynos. The addition of the two engine dynos brought the next level of quality control since they could now test and tune each engine that they built to ensure it was perfect before being delivered to the customer.
