Swamp rat is absolutely correct,give or take about 2hrs,fist time it took me about close to 3hrs due to SW pipes needed modification,PPE catted DP,the process was smoother than butter,perfect fit,like oem,used original gaskets and bolts and washers supplied by PPE,by the way took me about an hour and half the second time,put some antseize when install will help,also a fair $$ would be around 200.00,correct me if I am wrong
