So my mustang has 154K miles on the engine and was wondering the pros and cons of just rebuilding my engine vs buying a new one.
Well i am building up the upper end. Like heads, intake, cam n i am wondering if a stock bottom end will hold up to the different upper parts?
Yeah? A lot of guys on here are running stock bottom ends with modest and even massive top ends.Well i am building up the upper end. Like heads, intake, cam n i am wondering if a stock bottom end will hold up to the different upper parts?
The stock bottom end will hold up to just about anything you throw at it, minus the limits of the stock block. You're not going to break it with a H/C/I upgrade, that's for sure.Yeah? A lot of guys on here are running stock bottom ends with modest and even massive top ends.
Yeah I've heard you'll break the block before you ever break a stock crank, but I'm most certainly not going to test that theory lolThe stock bottom end will hold up to just about anything you throw at it, minus the limits of the stock block.

...unless of course you buy a cam that's too agressive or a set of heads with really large valves and smash one into a piston.
Assuming your engine is in decent mechanical condition (reasonable mileage, no excessive bearing wear, or worn rings, etc), you're a long, long way from breaking the bottom end with that set up.Well this is the list i wanna do n i am hoping the stock bottom end will hold up fine
Gt40x heads
1.7 roller rockers
Trickflow Stage 1 cam
70mm throttle body
76mm Mass air meter
GT40 intake
24lb injectors
high pressure fuel pump
fuel regulator
So a stock bottom end will be fine with this set up right?
x2 what 200xp said. AFR or TW heads are light years ahead of the X heads.
