I ask this question because i got my block bored .20 over. I've ask a few of mechanics and some say i need it and some say i dont. Some of them tell me not to get it because it keeps water from flowing properly and what not. What do you guys think? what should i do?. Thanks for any help

IMO they are pretty worthless.

i've installed several with no cooling problems. if your going to boost it would be in your best interest to get one,they are not very expensive.

Where can i buy one online?? and how much should i spect to pay??

$150

search classifieds

prospeed is selling a NUFORMZ in classifieds.

$150? you can get them at race engineering for $100

You might want to enlarge the coolant holes tho.

race engineerings are very high quality and are about 100 dollars

you might want to search past posts; there are alot of opinions on them.

I've heard of people doing this in the past. How large can they be enlarged before the strength of the blockgaurd is compromised.

You can also pin the block sleeves.

It is not important to use a blockguard at 0.020. In fact, it is not ever necessary. If you bore out your block far enough to feel uncomfortable about the major load axes, you minor axes are already too thin (buy a new block). The key is proper engine management with good tuning.

We run 400+ WHP on a stock casting (0.020 over) without a blockguard... in a DAILY DRIVEN street car.

tuning, tuning, and tuning...

nuff said..block guard can work very well to your advantage...but it can haunt you as well for incorrect installation..

do a search, and you'll find a lot of topics about it...

me, IMO, I'd stay without it and invest the money on tuning...
