These are pictures of the new 351 Windsor Engine I helped build for my 1970 Cougar. I used Edlebrock Performer Heads, Edelbrock Performer RPM intake, Ford Racing Roller Rockers, Dual Roller Timing chain, Crower Camshaft and hardened pushrods. All of this was added to a newly machined original 1972 Windsor block that was bored over .030. The engine runs very smooth and has lots of power to make my Cougar growl!
