i'm a bout to purchase a savage 21. are you saying that I will be able to swap the 21 for a 25 for free??
nope u need to pay 99bux to swap and theyll take it in any condition so enjoy that engine first till u get its last run then swap it ..
if im gettin an engine my picks are
wasp or picco26mach26 ....sirio27 is too much $$ unless u can afford it maybe u can give it a try see what is the difference between a
$180 engine to a $300+ engine
