What is the biggest/best cam to use w/ gt40 y302 heads and regular cast iron gt40's??
he will need to change the valve springs,and you haft to watch for ptv clearance that means watching for overlap, valve timing and lift.doesnt matter how big it is, matters how much it compliments the other parts...custom cam is the best way to do that...but if you're gunna do off-the shelf cam, then comp, crane, crower, lunati all make good cams, the trick flows arent bad either...but i know the f303 is one of the biggest cams you can do with the stock valve relief and thats only .512" lift...so cant be much more than that..and thats too big for the stock valve springs..so idk
i wouldnt do the steeda cam..the e303 cam sucks..if anything i'd do the f303 cam..and stage 2 is way to big for that set-up..even stage 1 would be to big...I'm asking for a friend who's bought a gt40 intake and looking at stock gt40 heads. He wants the best he can do for his dollar and gt40s aren't too expensive. People told me he should do an e cam or steeda #19 or maybe even an trick flow stage 2....not too sure....I used a lunati voodoo w/ the systemax kit but not sure if it'd be too much. Also like comp cams but not sure whats the biggest he could do for now an also be good for a future head upgrade.
