what kind of CI's can you get from a factory 4.6 block?
are the blocks made in different factories capable of different bore or stroke limitations?

with an aluminum block you can bore out to .160 over or 302CI

the iron blocks aren't any good past 302 cubes, CHP makes a 310 i believe based on the cast iron GT block but i dont like it.

the aluminum cobra/mach 1 blocks are good for more, VT makes 302, 304, 324 cubic inch strokers, and MPH was supposed to be working on a 331, but i dont know how it turned out.

David_K

hes stalking bore not stroke the 310 is a stroke and a 20 over bore.

we were writing responces at the same time, his posted before mine. i was responding to the thread started who was inquiring about both.

David_K

you cant bore the iron block out to 302 either. yo uhave to sleeve an aluminum block to reach that displacement from a bore alone

BCisme

why would you want to bore it so much anyways? VT's big bore engines are aluminum based and displace 304, if your going to bore it more than just enough to recondition the cylinders, why not just stroke it too?

David_K

link me to an iron block bored .160 over

BCisme

misread your question. sorry. it can be done im sure, but no gurantee it'll work.

David_K

i think you were thinking about stroker kits
