I know you have to build the blocks up for Mad Boost, What one B18b or B20

and what head, B16 or GSR.

 

LS

 

to my understanding, b20 block = thin cylinder walls, more prone to failure than the ls block under high boost.

 

Are you planning on sleeving the block?

 

LS, B16

 

depends on what you plan on doing with everything..... for the block I would say LS.... for the head if you where going to port and polish then I would say GSR. But if your not really going to mess with the head and leave the ports stock then a B16

 

I plan on trying to pull at least 360hp at the wheels. and I am ready to put alot of Money in it. Thanks for your help.
