OK, I flew out to denver from upstate new york to help my brother in law install a new 350 in his 87 blazer and with the combination of him being new to this and having a do it all tool kit in a plastic box, I am running out of time!!! He lives in thornton, 136th and colorado. I got the old motor pulled, the new one's here, already broke 2 of his sockets and a few extensions. The harmonic balancer installer we rented from autozone doesn't fit his crank for some strange reason too. We will be working on it tomorrow and probably thursday. This will be my first injected swap too, so if anyone on here has any advice, I'm listening!!!
