runing out of idea´s on what to improve

383 man i know you have a realy good point there but i am afraid my cam puts the power where a dualplane manifold just wont cut it since my engine already has very limmited torque down low compared to what is available at high rpm i think i will have to let this smallblock scream, but if it had been a litle less of a screamer engine i would have listen very carefull about the performer rpm manifold i know you have lots of knowledge about strongrunning engines that work well and runs lots faster than most would gues;)

rumblefish360 i realy wish those heads had been available with stock rockersetups;) but i hope the eddy heads will cut it for this summer and maybe more with some porting i know of a few very good people that can make wonders with cylinderheads but its not for free

anyone having any idea´about where the limit is for the eddy heads ? will they flow enough air to get me past the 500hp barrier? i dont realy care about a cerain number its just interesting to see how much power it will make and then count some on the performance.
iam also thinking about that nitrous got dart sugested but iam looking for more natural power first and then i will try the nitrous when i cant scare myself with all motorpower;)
right know my goal is low 12.s or high 11second 1/4s but i realise that is for serius cars with brutal power...
