I'm having problems putting back together my son’s blaster engine. We have a 1999 blaster that we split the casing. We bought a new hot rods crank and top end kit. When we split the casing, we figured that it would be relatively easy to put back together. But it’s not as easy and we figured, especially with all the gears. I pretty mechanically inclined, rebuilding Chevy engines, but this is a whole new subject for me. I've been looking for a step by step guide on how the engine goes together. Is there a posting that I missed that explains this, or is there a particular manual that I can purchase or download? Any help will be appreciated.
