R&R 4.3 'W' in 95 Blazer

I'm going to be swapping out engines pretty soon here in my 95 Blazer. Wondering if there are any tips/tricks/advice anyone has for me.

Thanks,

Joe

On the 4.3 Wseries...I would not let it sit for long period of time with old gas in the intake...as these tend to gum up the poppets in the upper intake...anyway you can use a strong injector cleaner once a year to clean the injectors...$21. bottle GM product...Wish You Well...

Is the truck a TBI or MFI engine?

W Vin--CPI system

So its a lt1 style injection system?

I believe so, spider injection system, through the manifold, I've got an upper and lower intake manifold, CPI system is located on top of the lower intake manifold and below the upper plenum...
