2056 questions, Special pushrods for 2.0 crank in 1.8 block? Options

[70_914]

Finally working on getting my engine put together, so wanted to get an idea on any pitfalls when building a stroker and big bore engine. I am sure there are plenty of people that have done this build and who may have insight. Pushrod length normal or do I need chromoly ones made? Spaces under the jugs? Spacers under the heads? Spacers under the rocker pedestals? Machine work inside the block to make it all work?

This is my first type 4 engine, but I have built 2 stock and 1 big bore type 1 engines, mazda b2200, 427 chevy hilborn injected engine, a mean little rabbit engine, my SHO v6 and a few others when I was in school. I am not looking for any basics, just anything wierd when building a type 4 bigger and better.

Thanks

Kevin

You can just about bet when you space a cylinder jug out further and move the head out, it is logical the pushrod will need to be longer by about the same amount unless the base circle of the cam got smaller and then that let the lifter set closer to the center of the case. It will be measure as you go or buy a ready made kit and pay someone else to do the measuring for you.
