Was wondering if anybody could help me out. Long story short I'm tring to revive my old t maxx. My spare engine is a hpi .25. After I put my flywheel ,clutch ,clutch bell on. The crank shaft is to long and hits my transmission and doesn't line up with the spur gear. It's about a 4 or 5 mm difference. So my options are a thicker fly wheel or a spacer to move everything forward to allow for room. I took a pic if it helps any and can take more if need.

I'm not sure about your ride ,but sometimes the only option is a different engine mount that allows
you to adjust the engine back & fourth!
Most stock engine mount only slide one way!

Other option is to cut crankshaft an install a pilot shaft!:cool:

There is different engine mounts that allow you to to slide the engine either way!
 
i have plenty of adjustment with my motor mounts i could just stick a bearing on before my flywheel i guess. was tring to find a proper fix.

If you shim the flywheel up the collet will loosen and the flywheel will just spin.

There are big block mounting kits and chassis for the tmaxx
 
You just need shims. OFNA used to sell a shim kit, but they went belly up. If you want to use a bearing, you need to destroy it and remove the outer race/cage then only use the inner bearing race. I've done that with old 5mm ID bearings so I could have tall 5mm shims for things.

Curious how you have enough room behind a big block to fit a pipe manifold without hitting the tower. On my old XTM big block max, it was extended close to an inch to allow room for the longer big block and larger header.
 
I'm looming at the pic. Looks like adjustable moynts with room to slide foward.
 
The transmission is in the way when I try to slide it forward. I ended up cutting 4 mm of my crank
