10.5/1 compression
Edelbrock round port heads cnc flowed to 330+ cfm.
Lunati hydraulic roller cam with .625 lift at the valves and .254 duration at .050 lift.
Performer RPM manifold with Pro Systems 850 custom carb.
Dougs 1 7/8" full length round port headers.
All logos and names milled off and evertything painted 65 Pontiac blue. Looks bone stock for a quick peek under the hood lol.
