8.1 Marine injectors (42 lb)up to 10 lbs of boost,with a walbro 255 intank pump

This is assuming you are running a truck intake and staying under 10psi
or 500 rwhp.....Worked for me, idc was at 100% above listed max numbers and stayed at 80% around 9psi 0r 460 rwhp iirc

-I would always run a little bigger though maybe some 60's..alot of variables

Thanks Nasty and Ribeiro. THe engine is in my 80 Z28. Stock truck intake. I run an Aeromotive A1000 fuel pump. Hp goal will be around 650 rwhp. Plan on upgrading intake to LS6 likely.
