Hey, just wanted to know the advantages of having a forged 347 or a 370ci engine? I do know that the 370 is Iron and the 347 is Aluminium...wow im smart

Anyway when it came to heads/cam would they be the same? Will the extra ci help? Thanks!

 

you can make an aluminum 370ci engine, just sleeve a 5.7L LS1 or bore a LS2 block .030" over. heads will fit but as far as cam the 370 needs a cam for that many cubes, not 347; to make maximum HP. imo the extra cubes are always better.
