stock looking engine , BIG POWER |||

............ aluminium heads , dual plane intake , maybe stroke it but everything that can be painted and hidden

First, no aluminum head I've ever seen "looks factory" I don't care what color it's painted

Second, trying to pull this off might be fun, but it SURE will be VERY expensive. Someone mentioned F.A.S.T. This is a shining example of "how cool" this is, but I can assure you, this is VERY expensive in terms of 'bang for the buck'
