replacement engine

[ToddF]

Jasper or MichiganMotorz, these seem to be the two big guys, has anyone had any experience with either of these.

 

About how many hours labor is an engine swap for a shop,

any thoughts are appreciated

I'd use MichiganMotorz personally. Had decent luck buying parts.

 

I'd buy a new crate over a rebuild

I've done a Jasper, 2 ATK's and one local rebuild (just one of these engines were marine). Jasper was the worst.

@ToddF : If a GM engine that you need to replace, as noted by @oldjeep a GM crate engine is a good option. You also have a variety of upgrade options available from the various crate options. If you do decide to deviate from an exact replacement, just note that the marine engine does have a specific marine camshaft which is a specific grind.

@dw I was planning on getting a replacement no upgrades

 

It seems Michigan has no core charge where Jasper does, I could probably get a couple hundred dollars for the engine.

@ToddF : Probably, what is it and what is wrong with it?

Spun Bearing, wrist pin, something internal, I had low oil pressure and then the noise, so to coincidental to be something else. a loud metal knock that increases with rpm.
