Ported 5.3 heads with a 10.75.1 compression

I had a highway tune and after I install the FAST fuel rails and 60lb injectors and a 100mm MAF I will be taking it to be dyno tuned.

Good luck on your next dyno pull. Just remember that dyno numbers are just that. Only numbers. A mere tuning tool. Is it the same dyno you got your current numbers ?

Again good luck.

stage 3 patriot 5.3L heads
stock rebuilt 5.7L ls1
1.75 ratio roller rockers
kooks long tubes to 2.5" y to a single 3" exhaust (no cats) borla xr-1 race muffler..
stage 3 spec clutch
descreened maf sensor
stock ls1 intake and throttle body
voodoo .567" lift cam at 228 dur 113 LSA

so far ive put down 397whp, and 430ft/lbs all at the wheels.. you can find my dyno sheet in the dyno section on here..

my goals are simple break 500whp using my heads and stock cubes with no boost..

I understand the ls1 intake is a restriction and if i change now to a ls6 id prob be close to 410whp with that alone.. and i also know I will need a larger camshaft.

this is all put through a t56 trans..

tell me which cam i should pick to do this on the stock cubes and natural aspiration while being fairly streetable.. it will be a weekend cruiser for me not a daily driver.. but id like decent mileage out of it too of course..

I always could just spray nitrous on top of what I already have but id like to have the power all the time and no refill costs. what ya all think??

Not trying to be a douchebag, but I really don't think it's possible.

I'm pretty sure those numbers are with the 125.
