Alright im kinda half and half on descideing if i have a l05 or not the guy said its 5.7 and a 350 and i havent had time ot take of the alt to look at the casting number but i was wondering what do you think a l05 would run in a stock camaro?

 

Probably mid to low 15's. I think you can look on the back of the block and there should be a "5.7" on it if its a 350.

 

I agree. The LO5 sadly is not much better than the LO3 and should run a few ticks quicker in stock form. However modding it will take you a lot farther than its 305 cousin.

 

Yeah the L05 is definetly not the best motor in the world. I would think that a stock L05 would probably run in the mid 15's with an in our cars depending on gearing and which tranny you have. My car ran like a 15.1 with the an L05 and 3.08 gears when I first put it in, but the motor came out of a modded truck and I dont know if the guy did anything to the heads or if he swapped cams.The L05 has 40 more hp and like 40 more foot pounds of torque than the L03 and it will defnetly respon better to any mods you do to it so I think its a great base to start with.

 

And the L05 runs just as long as the L03, forever. (I suppose the fact that the cam barely moves the valves off their seats has something to do with it.)

 

With jsut the L05 and the stock exaust and such its going to be a pig. The shortblock is ok, though. With some small chamber heads like a worked over set of 081's or 416's, decent cam, exaust, TC and gears it would probably do ok.

 

Low power output, low RPM band, and minimal amount of parts make the TBI motor last long. It is not uncommon to get 200K with ease.

 

Your not kidding Shiffty my friend just hit the 275,000 mark in his 88 Firebird L03. Who says that GM motors don't last???
