wilbur Posted March 25, 2015 Share Posted March 25, 2015 The left and right are the same, but don't think a 350 will do the job. Quote Link to comment Share on other sites More sharing options...
PaulR Posted March 25, 2015 Author Share Posted March 25, 2015 Is there any way to increase hp on 350 Quote Link to comment Share on other sites More sharing options...
Mackpro Posted March 25, 2015 Share Posted March 25, 2015 Its more than an ECM swap. Your ECM and be downloaded to a 400 with no parts change however a bigger crank balancer is recomended. To go to a 427/460 you need turbo and injectors, camshaft removed and off set key way installed in cam gear ( or it will run hot, trust me it will). And of course download the ECM bumped to 427 or 427. This is on the eairler ETECH's 1998-2001. 2002 and up CCRS and ASET style has fixed cam gear key way so you dont mess with the cam. This is how the dealership/factory says to do it. You could always go to some aftermarket injectors and turbo. Just swapping an ECM is risky. Different software levels and options could really hurt instead of help Quote Link to comment Share on other sites More sharing options...
bts-4120 Posted March 26, 2015 Share Posted March 26, 2015 sounds like he has a 460 but the ecm took a dump? Quote Link to comment Share on other sites More sharing options...
PaulR Posted March 27, 2015 Author Share Posted March 27, 2015 It's actually a tractor hook to dump trailer for local only can't find a 460 at salvage yard around only one they have are 350 but lf hand side ecm. Still unsure about the hp but we have one w/350 and still do the work. Quote Link to comment Share on other sites More sharing options...
