? about 4.3

[Pat Adkins]

How much different is the syclone motor as opposed to the 4.3 that comes in the new extreme? I have a spare turbo, downpipe,test pipe,walbro fuel pump,injectors. I figured that my cousin would only need a cam,intercooler,headers off a syclone & a modded ecm to be able to make this work. Am I forgeting anything? Thanks, Pat

Pistons and Compression ratio, main caps, the newer blocks are balanced shafts and most people agree are weaker.


If you don't change out pistons, I suspect the motor's life will be short lived. Syty rods are marginal at best, the newer rods are just slightly better.

Be a ticking time bomb IMO.
