1970 GTO LS Turbo

[sennygoat]

Hello everyone, my name is Josh and I have a 1970 GTO to rebuild. It is complete but rough. I have torn it down to body, frame and powertrain left. It is a rust bucket. Bought another clean 70 GTO body out of Reno. After spending weeks, slowly realizing rebuilding a Pontiac motor by anyone good will cost a small fortune. I decided to go LS. I am shooting for a $15k budget. I am going to Turbocharge the LQ4 block out of a2005 H2. Its a 6.0L iron block, aluminum head truck motor. I am either going to fully build the motor or leave it stock. Shooting for 500-600 whp. 4l80E trans. Stock rearendwth 3.23s. Will post picks soon.
