ya you need a GOOD straight edge. not a ruler. and runn it across the block. if its even a hair above the rest of the flat part of the block its going to increase the chance of it leaking. imo it would be a good idea to take it out of the car. you dont want to do all that work only to find out it has to come out anyways.
and looking at those pics again unless its the camera angle that part of the block def is not flat across. you can see the distortion on the edge.

Thanks for everyones input with this one... We ended up pulling the motor and changing the block, head and bearings.... Better safe then sorry! Hopefully our next post will be about how fast we got this 6 spd car to go and not how we blew it up again...

That's probably a good choice. I also compromised an alum block, prob will be fine for n/a needs, but for heavy spraying I opted to go with an iron LQ9 block.
One of the reasons i went with a dedicated fuel system tied into my main tank was to insure that i had full race gas when spraying. To many guys mix and match when running a typical stand alone, and that can be OK for smaller shots, but once we get to a certain point there is no room for compromise and thus the need for 100% race fuel. I don't know why this doesn't catch on more, as it's just as easy and simpler IMO.

yes. to me it defeats the real purpose of race gas if we water it down with street gas. some guys have no real idea what octane they end up with. I have mine set-up with some quick disconects that allows changing my fuel in the main tank out to race gas in a matter of minutes, and visa versa should I have enough race gas to save after a day of racing.
