yeah actually it did amuse me. You put that same $2500 into a 350 and you're going to make more power plain and simple. Why try and build up a smogger engine that was NEVER intended to be a performance engine in the first place when he could swap in a newer and MUCH better engine and be done with it.


Not to mention you don't even have any dyno numbers to back up your claims

 

I actually have done a little work to this engine that's making me think that I should stick it out with fixing the LG4 up. I don't need a dragstrip runner or anything just something to run on the streets against the cars it used to go against. I have an Edelbrock Performer intake, a Holley carb, a 3.08 rear-end, and a few other small things. It just seems at though since this guy did a bad job rebuilding my engine it's been slower. I used to take on 98+ Mustang GT's with no problem and now I wouldn't even put it up against my Saturn L300. It still runs good it just has problems getting up and going. I know I wouldn't be disappointed with the LT1 but I want to stick by my LG4 if I can. How did you get so much power out of your LG4, 85_305?

 

I said I havn't spent anywhere NEAR 2500 on my LG4 But if I *did* have that much I guarantee you I would be putting the hurt on modded LS1's. Thats a fact.

 

Well lets just say almost nothing inside of that engine is stock. Ya, I still have the stock heads (for now..) but they are not "stock" heads

 

I love the smogger comments on 305's, like the 350's and every other engine since the late 70's don't have emissions control devices on them.

 

Never underestimate modded LS1s...

 

good call /\ bolt on LS1s are rather quick! i have an LT1 with harness and PCM for sale, 850 complete, if you want the link to the for sale thread on here, pm me.

 

Thats a key point I try to make very clear in ALL 305 related threads

Although I must admit you *can* get a 305 up to LS1 factory specs w/out too much problem

 

I disagree, nething more than full bolt on is "too much problem" and a full bolt on 305 will not compare to a stock LS1.

But yea obviously you can get one up to LS1 level, you can get 4 cylinders and v6s there too... :-/

 

I'm not trying to be an ***, or braggart...I love 3rd Gens and am currently looking for another one. FWIW, my LS1 Z28 made 576rwhp/590rwtq in a car that I could commute to work in...

 

Ya I know a full-bolt on LS1 would eat a 305
But hey; if you put boltons on an LS1 you must be trying to be a viper because they already have 450+hp

 

uhh..you dont have any dyno numbers, do you have any track times? alot of people who estimate their horsepower numbers turn out to be quite wrong.
and with your 305, you think you have more torque then an lt1 or l98?

 

I was noting the fact that from the get-go the 305 was designed and built only to be a semi-performance oriented smogger engine. It was never intended to be a high-performance engine.

 

I'd have to say if you are thinking a fully built LG4 is going to waste anything besides bone stock LT1s, you are dreaming. Sure, the LG4 has plenty of potential since it came so horribly restricted from the factory, but it's still no match for the LT1, which has a 45 cid advantage to begin with, not to mention better heads, induction, camshaft and ignition than the lowly LG4 straight from the factory.

Of course, there are ways to reach power levels not commonly seen out of 305s (something to the tune of 300+ RWHP), but by that time the 305 is going to be a gas-guzzling pig with no street manners whatsoever. The LT1 with a few bolt ons will be making more power with better gas milage and better street manners than the 305 ever will.

This isn't to say that building the LG4 isn't a good idea, though. I am in the process of doing that myself at the moment. With a few "simple" mods such as headers, intake and rear end gears, the LG4 can be a decent performer for mild street use. Just don't expect miracles out of it when you come against an LT1/LS1, which is just all around better engines.

 

Compare what I have and then follow all the other 305 build up's out there. Only catch is I have done more to my 305 than they have
