Hey i know u guys had heard this question countless of times, but i need to know. Is a block guard worth using. I have read magazines where people had use block guards and running 17 psi of boost. On my setup i have 8.5:1 compression srp pistons and eagle rods plus the crank have been balance. On the top end kms performance double valve springs and titanium retainer, also crower stage 2 turbo cams with adjustable camgears. But right now i am still trying to find out what intake manifold should i use. Because with this setup i am trying to about at least 310-320 whp. But i want to know is using a block guard good for a insurance purpose right now until i can get the nlock sleeved. Or should i run the stock block with areally good tune.
