Depends on the dyno! Stock LS1's on mine only make 265-275 and I've done a few setups similar to yours only they had non stock camshafts and they were in the mid 400's. What year car/LS1 is it? 01-02 car will make a little more power just due to the ls6 intake flowing better. 98 car will have more trouble due to the crap heads on them.
Either way it'll be a fun setup for sure!

If hes on a mustang dyno, and its not a strong motor "factory beast" , then hes probably going to be somewhere around 440-450.
all comes down to how happy the motor is, and how the tuner manipulates the tune with the meth.

I used stock lifters, pushrods, rockers and I have been running 25lbs of boost and still holding. Have it tuned down to 15lbs now. This is on an engine with 180,000 miles. No way I would bother with pushrods.

i made 501 md with 6psi baby cam, springs and ud pulley on otherwise stock 98 ls1 6 speed. We were out of stock fuel pump and inj but probably could have made a little more. Stock motor should make 500+ 8+lbs. Think i picked up roughly 25hp/lb

Verdad Gallardo if you plan on blowing it in a few pieces might be better to wait on the cam unless its cheap enough. When mine let go a bunch of debris got caught on the rollers scarring the cam. Was just a 100$ cl special and 170k motor for me but just a thought if you want salvage anything
i did swap a 255 pump in shortly after and ran 8-9lbs for a year and 20k
