There's plenty of 400+ stock block LSJ's out there and running fine still. And it's SITE since Im being a know-it-all lol (jk)

 

Are you still up ?

 

looks sweet!!!!!!

 

Thanks!

 

Car may be running as soon as this weekend! Updates to come!

 

Ill be at smg all day tomorrow

 

Sweet man. My rods are suppose to arrive there today. Feel free to take pictures of anything and post!

 

lol ok.

 

Added new picture to first post. Picture of sleeved block after pistons and rods installed

 

curious what the sleeve job and pistons/rods cost you, pm me prices if you dont want to talk openly about them, understandable.

 

Man that is gonna be sick when its back on the road. When my engine dies (from old age) I want to put in the short block and have SMG have a field day with it.

Ran into a hold up with the build. While using ZZP’s Ecotec 4340 Connecting Rods the pistons are up just a little too much which will not work with the current Cometic c5921-027 Head Gasket normally used on the LSJ. If i were to put it together as is it would run at high compression. The gasket I now need is the C5921-051 which is a thicker head gasket made by cometic. So I have been on a massive search calling every website on google including cometic themselves. No luck! Typically it takes cometic 5 days to build the gasket then another few days to ship out. Cometic themselves was the best help and said they would get it made in 1 day then ship it out for overnight (instead of the usual 5 days it takes them to make). So the car won’t be able to run this weekend as planned and for now SMG is going to get as much work done that he can do to the rest of the car while we wait for the gasket to arrive. Here are a couple picture of the block to show you what I’m talking about.

 

is that the 9.5to1 pistons

 

yup.. stuck with stock compression

 

Did you try ttr? Aaron normally has the weirdest eco/jbody **** in stock for some reason.

 

considering the stock pistons protrude out of the deck i doubt you would see much of a compression increase

 

yeah, I tried just about every forum vendor as well as ebay, google and amazon.

 

Yea forget the exact reason. It may have to be due to the combination of the cams I’m running along with the rods/pistons. I’ll talk to Fred from SMG tomorrow probably and get the exact reason.

 

i bet it is from where the they had to deck the block i would check the piston to valvr clearance and if it was run it

 

well I ran into some difficulties in getting this head gasket... the wrong head gasket was ordered somehow to the previous company i tried ordering from so I decided to just call Cometic themselves (which I should have done from the get-go) They were able to help me out and are going to get the gasket made in 1 day and shipped out tomorrow for overnight delivery. However no further work will be done to my car until next week as SMG will not be open until Monday or Tuesday. So hopefully I’ll have a good update by then.

 

first post updated! Added 6 new pictures of the motor being assembled

 

hey kango i checked how far my pistons stuck out of the block they were at 0.050 piston to valve clearancnce was plenty good also

 

dude thats awesome, youve GOT to be getting exited now seeing it all come back together. im stoked and its not even my car

 

Haha yeah I am... Just dying to hear this start up for the first time!
