Mike,

Have you determined if the axle from the final drive to the passenger side
clears the main bearings and crank / rod throws?

Regards,

Subject: [GMCnet] new engines for the GMCs

Some of you may be following this from the Facebook page. I have been
looking into the viability of the LS engines for GMC motorhomes. Problem
number
one was getting the LS engine to hook to our 425 transmissions. The Panrail
on the LS interferes with our differential. I solved the connection
problem by rotating the transmission up about 25°. That allows clearance
around the Panrail and diff. The next problem was the transmission now
interferes with the step area. It could be worked around but it illuminates
a True Bolt-in situation. I have identified an aftermarket block that
would get us 427 in.³ relatively easily. And still fit in the stock
location. The target for the horsepower of this engine would be 450 HP and
500
pounds of torque. They can have late-model fuel injection and coil on plug
spark system. I'm ready for questions
