I am getting rid of that crappy VG30 and installing an L28.
The first thing I must do is convert it from a rear sump to a front sump.
 
 


Moving the pick up to the front of the block.









 

 
All Finished!

Now it is time to port & polish the N42 head.
 
I installed 202sst Intake valves and 40mm sst exhaust valves. Thats all I could squeeze into this headBig smile
 
The cam was ground by American Cam.
 
It is a 555L 300Dur on 106* lobe centers.
 
If my math is correct I should get about 8265 RPM out of this engine and just under 350 H.P. with 312ft/lbs of torque Naturally aspirated!
 
I will be using 45mm webers and I will fabricate a custom set of sst Headers.
