Inliners International Forums General Discussion Truck Talk Swaps for Chev.52 COE

Hey Gang,
Own a Chev.52 COE w/ the original 235 babbitt bearing engine.A frame up resto is tentatvely planned to start in Sept....so opinions welcome!!
Would love to have a full pressure 261 installed to replace the 235 for the obvious reasons.I've heard this is pretty much a modification free swap.Is what I've learned correct??
This truck is equipped w/ the 2 speed rearend. Since I'm looking to add a little bit of highway speed (10-12 mph)are there later rearends from a C-60 that could be considered. I don't know what ratios are found on these newer models.Finally,would a later rearend fit my truck??
