I have been wrestling with the cost of engine replacement and cost vs. drive-ability. I have received a lot of advisement (thanks to all!) and have talked to many many folks.
So, I have made this handy comparison chart to assist me in tracking expenses. I am counting on a cooling fan upgrade to fix my cooling issue since my current fan is tiny with a tiny shroud.
Has any one used the GM350 / 290HP engine before? Any idea if it is worthy of the cost?
I know the first thing you have to assess is what you are going to use the vehicle for.
My vehicle will realistically see 4000 miles a year of mostly highway driving at 70mph to take me to and from work. The rest of the time will be around town and probably two or three weekends a year of very light off roading. I do not plan on ever selling it, so that is not an issue.
I can do limited work in my driveway. However, it is completely uncovered and unsecured and my wife will get tired of looking at it torn apart after a few months. Due to this, I am factoring in labor for the LS engine, but can drop in in my driveway if just mating a new engine to the transmission currently installed.
Any input would be helpful and I am more than happy to update this spreadsheet.
Here is a link to the actual spreadsheet. https://docs.google.com/spreadsheet...YwRzNHNXYxRHBRTzR6c3pxUGc&usp=drive_web#gid=0

Cost of an LS/Gen III/IV | Pro - Power Con - 100K already on the clock Con - LOTS of additional work to install, I cannot install in my driveway | Cost of a Performance "Crate" motor | Pro - Power Pro - Easy to install as it is a drop in Con - expense | Cost of a GM350 / 290 HP | Pro - Might be reasonable power Pro - 87 Octane Pro - drops right in to existing setup Con - might be bored if the power is weak. | |||||
