    Changed 2012 Volvo 5.0 to 5.7 will not idle

    We recently replaced a Volvo 50GXiC-270-R block to a 5.7L GM longblock. I was told everything would work fine but the engine will not idle. Goes from running smooth at 650rpm's up to over a 1000 and running rough. I have a feeling the EGC will need to be replaced. Has anyone ran into this before...
