Hello everyone,I have a 95 Hummer H-1 with a gas 350 TBI vortec L05 engine. I now have to replace the engine due to water in the oil and due to the economy also Im trying to do a swap with another 350 TBI without doind any modifications. So im looking for an engine doner that will match mine that has a 4l80e transmission. The problem is when I look at an engine the person will tell me it will match right up even thought they have a 7004r transmission? Then I try to go on line and read that the intake manifold wont work because of the vortec heads bolt pattern.Then theres the change in horse power for some engines and Im told the computer has to be adjusted too,Im on a budget here and trying to take the path of least resistance.Just to clarify one thing please,everyone thinks cause you have a Hummer you are rich,thats not true here in this case.So if anyone has any info to give me I would really appreciate it.Thankyou very much......Truckless in Seattle.....Jerry G.
