"BOUGHT NOT BUILT"
whats the difference?
Yup, this got hashed out a year or so ago. Camshaft and ECM programming. EVERYTHING else is the same.cam and programing, as stated earlier, the first HO's had forged crank and pistons, now the entire assembly is the same except the cam, and there are some programing changes due to the cam
Unless they have changed it recently it's 375 vs 425 (50hp)I think they have the same short block, are the heads the same,
I know that they are 40 hp more
385 vs 425, but how is made?
HO specsdid you read that some where???? is it on your motor???
yep thats what i read, havn't seen 5150 anywhere but here
