Ive read up on plenty of threads and forums on K20A2/K24A4 builds on this website and other ones. Ive heard about K20Z1/K24A2 builds but no1 really goes into much details about those. I have a K20Z1 long block and want to do the Frank build. What I wanted to know was if it would be better to go with a K24A2 short block or K24A4 short block? And if I should go with the K24A2, would the build be exactly the same as a K20A2/K24A4, as in would all the same parts be needed. I.E. K24A2 short block and internals with K20Z1 head, oil pump, etc. Thanks in advance.
