there is no dyno i can use near where i live. when i did find one an hour away it was to expensive for this poor country boy.
so i was wandering if anyone has any educated guesses on how much horse power and torque i may be getting out of my '83:

rebuilt 305 with all new parts moly rings oem pistons (yeah went ahead and kept 305)
3 angle valve job w/ new valves (switching to world s/r heads soon ((extra 20-30 hp right?)))
holley 4160 carb
holley intake non egr
accel hei distributor with accel coil
lunati cam with .437/.454
roller lifters
roller rocker arms
4 into 1 headers with no oxygen sensor (off road use only supposedly)
flowmaster 40 series exhaust
electric fan (not pulley driven)
no emissions control or unnecessary vaccum lines
no AIR pump or components

do i at least have 300 horses. what do yall think

 

yea im almost positive that you should have 300 horse. even though its a 305 and all the mods you did esp. with the rebuild im guessing anywhere from 290-315.
