I actually intend on driving the thing to the ice cream shop from time to time. The shaking and rattling should give a nice message within the 10 to 15 mile trip. lol. A 4bt would be a much better fit and could be installed without any firewall hacking. Howeve, with the limited trans tunnel spacing, the floor would still have to be hacked. Talk about rattling, we ran a 4bt in a '92 1/2ton for about 4 years. Once a month, so we discovered, it was a good practice to grab some wrenches and check any and all bolts for tightness. Even with the factory engine mounts, this thing would rattle your teeth.
