69 RS/SS Camaro engine swap! 350 to LS3

Why would someone take out a perfectly running 400hp engine that commutes 800 miles a week to/from work, runs 13's in the 1/4 mile and gets 18+ mpg? Ooh, Ooh, I know..............BECAUSE THEY CAN!!!!
The new engine is a 427ci modified LS3 crate engine from TurnKey Engine Supply. This 550+ horsepower all aluminum powerplant will breathe through Edelbrock full length headers and x-pipe while passing power through a Tremec TKO600 5-speed transmission.
The old mill coming out was a perfectly running 4-bolt 350 GM crate motor w/ Edelbrock ETEC heads & roller cam. Performance at a Gearhead Garage track day put the car consistently into the 13's.
Other upgrades this round include: an aluminum dual pass radiator w/ twin SPAL electric fans, a Rick's Stainless fuel tank w/ internal Walbro fuel pump, a hydraulic cluctch conversion kit, DSE 7-speed wiper motor & DSE600 steering box, Hydratech Braking System hydroboost w/ Wilwood master cylinder, adjustable proportioning valve and a Hurst Roll Control Line-Lock.
