see rule number 14.....W-2 heads and intake aren't cheap....put a set of 302 heads on a low compression 360 and have them opened up to the 360 188. 160 valve size to keep it in the spirit of the rules for suspension keep her soft. chuck the sway bars to let the body have some movement...flip the front spring hangers to get some forward bite and to lower the rear end at the same time. keep everything legal and drive em clean will get you the best results
I did not see anything about moving the motor back.. I would set it back against the firewall and try and get the motor weight behind the shock towers.
