Hello Truckin,
I was thinking about getting one of the '88-'94 Chevy C/K trucks with a 5.7L manual five-speed transmission. I know you have tested the Banks mule pickup with its twin-turbo system that was backed by a Doug Nash six-speed. I have looked for a Doug Nash and other six-speeds, but I can't seem to find any. Is there any info that teaches how to modify a five-speed into a six-speed?

Chad,
Creating a six-speed from a five-speed isn't something to give more than two thoughts to. Your query is easily answered by checking out the offerings from both Richmond (www.richmondgear.com) and Tremec (www.tremec.com). Both companies offer six-speed transmissions with ratio choices that will suit your build perfectly.


Hello there,
I have some questions about "Small Cubes, Big Power" (Dec. '10). Did you have to replace the stock fuel pump, injectors, and ignition system? Also, is the FAST XFI management system in place just to tune the ECM to get optimal horsepower? I would like to run this engine set up in my off-road truck, so all the information you could give me would be really awesome.
Thanks, Christopher

Christopher,
Since this engine was run strictly on a dyno, we did not have a fuel pump to replace. In your truck you would not need to replace the fuel pump, but at the power levels we were reaching, it is highly recommended to at least get a 255lph unit. As for the injectors and ECM, we did run 36-pound injectors for tuning and the XFI is a stand-alone ECM designed to run engines when no other ECM is present. In your truck, the original ECM can be custom tuned in a similar fashion.
