A Stock 305 Pushes Around 230hp/200 foot lbs torque @ 4900RPMs. But, I dynod my 1985 El Camino 305 HO with an Eldelbrok performer intake, dished pistons, with 58cc heads and 9:1 pistons at around 302hp.
Must be wrong. I have just researched the engine in my '55 Chevy Pickup and find it is a 1984 305 LG4 which is rated at 150 hp.
The 305 HO is rated at 190 hp.
You did not say what YEAR 305 you started with.
FYI - buyer beware - it was sold on EBay as having a 350 cu in in it.
Around 150
The 305 HO was the highest power version.
The 305 "HO" was actually dropped after 1986. In '87, the base 305 TBI was rated at 170 hp, the 305 TPI was rated at 215 hp.
the 1986 Chevy truck 305 HO produced 180 hp
== 215 net horsepower, 285 ft.-lbs. of torque
Some where around 260 give or take 5 or so due to wear.
The factory rated it at 480@3600 rpm gross torque 335@4800 rpm gross horsepower. Ratings were changed in 1972 to SAE net.
The 2006 cummins is the most powerful of the 5.9's at 325 hp and 610 torque
220 horsepower
Yes, it came with the 4bbl 305 HO running at around 180hp The 8th digit will tell the engine. A "K" is a 5.0 liter 305.
