My goal is to build a 400rwhp motor but I am a little worried about the stock block, Are the Mexican blocks that much stronger than a stock block, where would I be able to find and what is a good price? What all has to be changed to use a Mexican block? Thanks for any Help
A stock block will handle 400 whp as long as you take the proper precautions like a main stud girdle ect. Dont use your money on a hard to find mexican block when you don't need it.
I agree with 2000xp8, girdle is a waste of money, all they do is keep your block together, after they've blown up. There are thousands of 400rwhp mustangs out there running stock blocks
