My 305 is toast and im looking into getting a goodwrench 350...anyways what do the 92-93 caprice fleetwood engines have HP wise? www.ftforce.com says 170hp and 255lbs...no way...

 

the HP and TQ you listed or for the L03. L05 is
210HP@4000 rpm, 300 ft lbs torque@2800 rpm

 

The GM Goodwrench comes with 249 hp @ 5200 rpms and 304ft/tq at like 3500 rpms.

This is not the L05 motor though, they're a little different. i believe the code is L51 or soemthing like that.

 

250 HP Ha! i really think those values from gm are way too optomistic for that engine. The head castings are kinda crappy and the stock cam is pretty weak. It looks like im getting around 220 HP out of my gmbadwrench 350. Ive spun it up to and past 5000 rpms, there aint much out there. And its not because of the throttle body i have the pressure drop is <10% in the manifold. Other than the lack of high end power, the engine is pretty decent for what it is. Gets good gas milage to boot.

 

That rating is with open headers and cast iron intake.

The cam in it doesn't produce much power past 3500 rpms.

 

Goodwrench is more of a type of engine, not a specific engine. Both the L05 and the LM1 are Goodwrench 350's.

I dunno exactly how much power and torque it has, but I should be running in the high 15's with my setup and little traction.

 

Get this.........motor is fine im retarded. A valve spring broke and I didn't notice it till i was pulling the timing chain cover

Oh well Im swapping cams now.

 

If you look on the TBI forum you'll find that a lot of guys are hitting low 14s with TBI 305s. That is decent performance, so you should really check over what they are doing. There are some pretty good mods to the injectors that are supposed to help.
