Thread: Gen V Swap Question

So, I am dumb and I forgot to get the 120mm and the 140mm bolt for my Gen V swap and now everything is closed for the holiday. I can get the 120mm at O'reilly's since they are open tomorrow and have it in stock, but I can't find the 140mm anywhere. How bad of an idea would it be to run the car without the 140mm bolt? I feel like it is a really bad idea since of the boost. Thanks.

what boost?
