Just paint it black with a rattle can, it'll do the job.

The problem with painting is you need to prep it well or it won't stick well.

Some guys have used POR15 Or other chassis type coatings.

In the past, I used PPG DPLF 90 directly after sand blasting and cleaning.

Now there is lots more choice. I would use an Epoxy type coating.

Summit even has its own brand Epoxy chassis paint.

I ordered some 3M Rubberized undercoating. Going to try it out.

Waiting on the machine shop still. Block and heads should be done friday.

I worked on replacing the plastic wire looms. Half of them fell apart due to heat. Got all done except the big one from the ECU, just waiting on larger diameter one.



I painted the cross member with 3M undercoating to keep it from rusting.

Got block and heads back from machine shop.

Now just need to clean it all and start assembly.

Did a quick bore check.

Pistons came at 4.0280

Bore at 4.0315

for a 0.0035 Piston to Wall clearance. Right where wiseco recommends it.



Heads all cleaned up, 3 angle valve job, Milled 0.010, ready for install.

I like the build, very similar to mine.

Measured the Rod Bearing clearances. With Std bearings I am getting 0.0017

Was hoping for 0.002 - 0.0025.

it's in spec for normal LQ9. Would you guys run them as is? This motor won't rev high or make over 450hp.

Should be fine, it's within the spec of a stock engine and those would handle far more than 450hp without any engine work.

Started engine assembly.

Filing rings is a pain in the ***, took forever.

Set the Top at 0.020 and bottom ring at 0.022, I did mess one up bottom ring and went to 0.027 somehow. Ordered a new ring to fix that one.

Painted the block and installed the crank, torqued the mains.



I did notice some damage to the block oil pan sealing surface. I have one deep scratch and one smaller one. How should I handle it? Not sure if gasket by itself will fill that gap. Should I put a dab of RTV in those spots?

Measured Crankshaft Endplay at 0.002, so right in spec.
