Hi I'm currently trying to get ideas for a nitrous setup 4.8. Stock 80k mile short block, what heads and compression should I go with? I was thinking either a 243 head or milled 317's id like to spray 175-250. And also I see nitrous cams are in the .600 lift range, big 240-260 duration and rpm range of 2400-7200. Would a cam like that be way too big for a 4.8? Plan on running a victor jr with plate and elbow. Any input would be great! Only thing I have now is the 4.8 and I have 2 sets of 862 heads and some 317's

Im not sure what head would be the best option on the 4.8 so I am of no help there. I did want to say if you decide to go with a 243 head I have a set of ported and extremely milled heads I would make you a good deal on.

yes pretty much track only. it'll be driven to track, roughly 15 miles each way. im leaning towards a 580-590 lift, and iwant the victor jr because i want a metal intake and i see it being the best option, because i can run a carb style nitrous plate.
243 heads will lower my compression a lil much for me. i didnt realize they were 9.5:1 stock. a friend of mine made 305rwhp with a 224r cam and headers with his 4.8 pickup. and ive heard of several guys running 200 shot on 100% stock trucks.
