Man get that comp down or this won't last !!!
And it will destroy every thing !!!
I had mate that did exactly this, had a 10:1 comp worked 355 stroker, he brought the car (vs ute) from a guy who built it and then went and put a blower on it when I told him not to and it lasted maybe 5000 km before goin bang and it ended in tears for him
What cam is this running ??? Please don't say something with 110 or 108 LSA N/A cam that it had in that motor to start with
But to ur problem have u got a catcher can that both valve covers go to with a filter on it ??? Blowen motors need something like this (good ventilation) it can not be sucked into engine like factory, if so do a pressure test on all cylinders to see if u have blowen rings and pressurising crank case from that
