I suppose I need to do a POSI-Lock if I get the 271, correct, as the vacumn stuff will be gone, correct?

 

do a search on TDR , BigBadDodge did a 271 converstion and posted the whole thing parts needed and how .

 

Or do a general search on BigBadDodge or Scott's Dodge Ram - just short of a bigfoot buildup, it's quite a truck.

NV4500, 271 with Ford output flange, 1.375 cross\bearings - can't really see what all was necessary, but been there, measured that for NV5600\271 package, don't want to cut\fishplate the frame.

All the extra steel he installed for the suspension components more than compensated for any frame surgery necessary for t\c clearance

Think I'll opt for a GM 261, get same strength in a narrower package - like the 271, comes in auto-shift and manual-shift versions.

Or, use an argon\co2\helium arc wrench to narrow my 271

Thanks for the input, folks........
