1998 engine swap
Hi,
I have a 1998 chevy cheyenne 2500 with a 6.5 turbo diesel (VIN# 1GCFC24S7WZ251336) and i'm trying to determine if the engine will fit in a 1998 chevy cheyenne 2500 4X4 with a 6.5 diesel (not sure if it's a turbo) with VIN# 1GCGK29F7WE231081; that i hope to purchase. According to www.decodethis.com, these engines have 2 different horsepower/torque rating which leads me to believe they're not the same engine. My question is are they the same engine (perhaps www.decodethis.com is not reliable/accurate) and are they interchangeable? According to some research i've done online, there are 2 to 4 different types of engines that could possibly be in my truck (VIN codes F, S, M, or J). I'm not sure if I have the "F" or "S" because I don't know which digit to look at in the vin #...can someone please help me? Thank you.

The basic power plant is the same, block, crank, piston. rods ect. the intake will can be different, from a heavy duty to a light duty(will have EGR) and computer programing again all the hard parts with exception of intake they are identical hope this helps good luck

Welcome to the Forums!
8th digit. F is HD, and S is LD. Your truck was OEM a LD (7200 GVWR), with EGR and less power than the HD engine (8600+ GVWR) you are looking to purchase, and it will have/had a turbo. The engines are identical, underneath the EPA stuff and programming.

7th digit in VIN is for the cab configuration. 4 is a regular cab, 9 is an extended cab...
