Eh I wrench and build my own motors so I know mine will out perform and out handle the aluminator any day of the week .. all info how to build these motors is available online (torque specs) and ring gaps to user specs but other than that pretty simple .. and best thing is I could build two short blocks for customers for what the aluminator costs..
while its true that you can build two short blocks for what an aluminator cost. you have to remember that the aluminator is a complete long block that only needs an alternator to run.
