Engine Swap Questions

[kaycee71]

I recently bought a Mack 2000 CH613 E7 350 mack engine

9-speed maxitorque with air suspension. However, I got a report after full inspection that the crank has gone bad and the head is no good. But the shop then offered to swap the engine with a 1985 Mack E6 350 Mechanical .

My questions are-

1. What are the Pro's and Con's if I do the SWAP or Fix the engine.

2. What should I be asking the local shop?

This will be my first Mack truck and it is already beginning to sound overwhelming.

Better to go back with a good used e-tec engine , the e-6 is way different front engine mount would have to b fabricated not to mention the electrical system would be a headache .

A mechanical throttle linkage would have to fabricated, engine mounts, all sorts of things not quite fitting or fabricated to fit, a true nightmare. Then when you need parts for this engine (e-6), with no true chassis number to go by----no thanks. I would avoid the head ache and replace like for like.
