Boosted slant?

I will say 5-7psi really wakes a slant up! I will also say so far mine has had No issues with that level and more ( on a fairly safe tune ). Even with .120 off the block, Stock pistons with some new rings and bearings. I wanted to put it together on the cheap before spending the money on fancy pistons or anything else. No methanol just a water to air intercooler. I have no doubt this thing would live a long life at 5-7psi maybe even a little more. unfortunately I will be building another short block sooner than wanted. this block has a crack in the water jacket and all the JB weld and sealer doesn't seem to want to hold anymore. I will also add I should have done this 15 years ago! when I first started collecting the parts to do it and was talked out of it.
