As far as locating the engine goes I am going to go by the location of the mounts on the factory frame. I drew some in CAD and should have them mid week. I know that front to back location will be close to the same as in the truck. I may be able to move it back an inch or maybe two. I will have to see how much clearance everyone else has there. Mine the firewall will be fabbed so I can do whatever there.
The height of the engine in the chassis is set by an absolute. That absolute is the auto trans oil pan. Since it cannot be modded in depth of 1/4" or more I feel like there is no sense in that. So the bottom of the trans oil pan sitting 1/2" above the bottom of the frame rails will be fine.
However this puts the engine oil pan about 3/4" below the bottom of the frame rails and also right where the engine crossmember is. So I will yank the oil pan and re work it and the sump to fit inside the frame rails and behind the engine crossmember. I will add a 3/16" thick plate on the bottom angled up at the front and back just in case it comes in contact with anything on the ground.
I ordered factory B series motor mounts as I stated above I drew the pieces for the frame in CAD. This is what the pieces look like before welding. They are drawin from measuring the factory mounts on the frame.
I also drew frame braces for the rear step notch. These will go into the top and front of the notch and the top and rear of the notch and will weld to each other.
And here are all the 4 link tabs.
And here are the watts link cranks. I actually drew these while I was on the cruise. I took my laptop and it has solidworks on it. lol
I will have to import the files for the fuel tank. More to come.
