250 xflow rod sizes

Ok we all know 250's have weak rods, but besides the hemi rod option, what size are the 250 rods, compared to say, clevo 351 or 302 rods?

Does anyone know of another rod to use (chev even) and what piston?

How much power are you planning on making?
I know of several turbo 250 Cortina's that have run under 10's with std rods..
I can you some bullet proof rods for $250 each....
Check out latter models?? I think only the rod length changed and mains from AU on???

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!

Re: 250 xflow rod sizes

dunno how much power exactly i wanna run, never enuf is there? i just hear that when u turbo a 250 the rods are only good for around 250kw, which will get me nowhere near 11-12's in an XA, and besides the hemi rod option (whom finding out which piston to run is like getting blood out of a stone) was wondering wat other option there was

Re: 250 xflow rod sizes

i hear there is a new method, instead of heat treating parts, there is a new way that deep freezes the parts which is apprently stonger than heat treating? i read about it in ZOOM magazine once but u think i can find the mag now? Anyone? Maybe if i get this done beats searching for new rods as i have STACKS of STD 250 ones

Re: 250 xflow rod sizes

250 rwkw will get you into low 12's...The thing to remember is set turbo up so max rpm is around 5800 rpm it'll last heaps...There are 500,000 250 blocks out there.Almost as many sohc 4.0 motors...
