Like I said...not for 4900.00n/a or not available
468 based on 4.310 bore and 4.00 stroke and conventional heads running 87 octane and make 680 hp is a tall order and limit it to 4900.00 were's the nos under the manifold.
youd better stand on 1 leg and youll be by yourselfI stand by my comment. You're not going to get 680 hp out of 468 cubes on 87 octane.
how about the 2005 emc 509 cubes rollercam motorsHasn't engine masters challenge built some big number, smaller cube, 91 octane motors?
