I ordered my crate from Jegs and was happy with two exceptions.  They sent the unit to a freight carrier 3 hours roundtrip from my home that I had to go get and haul back after I asked them to please send to one of the many carriers 20 minutes from the house. 

 

Secondly, see if your crate comes with the dipstick.  I didn't get the ZZ4 due to potentially changing out the hood.  That being said, I got the 330 hp motor.  Problem was that their literature did not mention a driver and passenger side dipstick.  I ordered a dipstick and it did not work and when I called them back I eventually ordered a stainless stick which looks great, but when I got it in, it would not work on the passenger side.  The dude told me it was for the driver side and I begged to differ with him.  Then he informed me of the driver side hole, which I and my two buddies missed getting the unit ready to install.  I had to order a $6 plug from the GM dealer close by.  That solved that!

 

I put the Dewitts aluminum radiator, dual spals and the March serpentine set up.  It was more than twice the GM set up and March says their system bolts right up.  Yes, it bolts right up after you tap the head on the passenger side into the water jacket and grind down the high dollar clear coated bracket so it will clear the intake manifold.  Their power steering pump is top notch though.  That saginaw pump I had was a PIA.  Plus getting around and adjusting the belt is a piece of cake; however, they can be out of stock on components for weeks.  I came close to cancelling my order with them after the third week of waiting.

 

Good Luck and enjoy,  I know I am!!!   Rick  

 

I got my engine from a local GM dealer that was a GMPP participant. They call me up when they ran a special on the engine I was interested in. I got my engine on sale for $2064 w/tax a few years ago. It was the 350 HO 330hp unit.

Kinda agree with Darryl(Sarge)... you are capable of doing it.  Just takes a wrench(or three) and a little time. Oh, and an engine hoist doesnt hurt either... just take your time with it and you'll do fine.  I also gotten my zz4 from jegs(355 horse, aluminum heads complete engine minus carb and starter...even came with the spark plugs) i did have to replace the water pump(came with a long) with a short one.  Again no biggie... (anyone in need of a long style pump? kidding... that was 5 years ago, not sure i could find it).  Good luck Jim
