Re: help with x-member

The clam shells use 3/8 x 1" bolts (3 each mount) and the crossmember should also be same bolts. (8 total on crossmember and top of frame)
clam shell mounts are garbage

Re: help with x-member

3/8" x 1.25" would prob be better on the x-member to frame rails to allow washers & full thread engagement.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

The bolts on the frame rail to crossmember are 9/16. Motor mounts use 3/8.
