My project 87 ls has a factory replacement engine. At 27,000 miles the motor had a nice mix of oil and antifreeze. My dad, who had the car since new, had the motor replaced under warranty by GM. I was told GM used the 350 as a replacement for the 305. Does anyone know if that is a fact or misinformation. As much as I want to put my 327 in I would rather keep all the numbers all matching as much as possible.

 

If you're looking at the car as an investment, you can never go wrong with "numbers matching".

 

yea, the 350 was had a bit more torque in it, chevy used it as a replacemen for the 305 in a lot of stuff during hte 90's if i recall my learnings correctly (WEHRE ARE YOU SPACE!?!!?!?)
