LO3 vs. 83ish Grand Prix

Backstory:
One of my good friends has a stock 99 grand prix GTP..on his way home earlier this year went to pass this kid who goes to our school who owns a 83ish GP, and the kid sees this and like floors it but to no avail as my friends GTP wipes the floor with him. Anyway, since then, every time my friend sees this kid (who has a large ******, so i will affectionally refer to him as '******' from now on), he always shouts halarious things at him such as 'hey dont get your hair stuck in the door! or "Hey buddy hows your car doin? havin fun in the snow?" Well after a lot of harassment by my friend, ****** got pissed and informed us that the reason his wasnt driving his car was because he was "doing work to it".

We all assumed an engine swap but he brang the car in for the first time in awhile today and we found out that he actually crashed it and he was fixing the door or something. In the parking lot after school today he had the hood popped and me and my friend went over to him. As i suspected it was the carbed 305 (145HP stock i think) with an open element. After my friend made the comment "i see the wheel, but where does the hamster go???" he told us that he was putting a 350 in it soon.

Now my question is, if he ever does put a 350 in will that thing be fast? Obviously i know there are millions of 350 combos, but using my excellent skill of stereotyping i would assume its going to be a very low budget build, carbed, probably out of an ever older vehicle than his 83 GP, with little or no newly purchased parts. Assuming he doesnt change gearing in the back (which i have no clue what it would be on that car), what do you think id need to take him? By the time my camaro comes out of hibernation in the spring it will have an open element, catback and hi flow cat. Maybe some UD pulleys.

I try to remain 100% conflict free, as i am very paranoid about people ****ing with my car, so i havent and will not trash talk the kid or mock him, but i would dearly love to see his face as i blow by him. That would be truely priceless.


EDIT: Ok so the word i we call him was censored so i will now refer to him as "hairstyle from 1980's boy"

Probably not.

I would agree with your assumption. Displacement doesn't mean much if you have no idea what parts are in it. He will probably get an old truck 350 that will make about the same power (140hp or so) as that LG4. It could even make less if it is a 70's smogger 350 with crap parts. If he puts in a late model LO5 (which he could since there are many out there) he could have 185 to 220hp (depending on the year). If he does indeed get a LO5 he will be a lot faster and could run solidly in the mid 15's. If he has a late model vortec 350 he could run into the low 15's and possibly high 14's. Those motors make around 260hp and 320 or so lb ft.

The mods you have planned for your car will help but not that much. Your car should be in the high 15's.

I would try to get some more info from him as to where he obtained this "350" and if he did anything to it.

Without that info you can only guess.

I'm gonna try to talk to him about the matter, and see whats up. I would think his brighest possibly might be a worn out LO5, but using my amazing stereotyping power i would say a vortec is almost certainly out of the question. Even so, regardless of if he puts a lo5 in there, we have to consider weight and gearing. I mean, as one could guess, there isnt a real big following of early 80's g-body fanatics and therefore there is like NO info whatsoever on their specs, but i would assume that car has atleast 200-300 pounds of weight more than my camaro...and i cant even theroerize as to what type of gearing it has.

Eh I wouldn't say that. There are plently of Malibu, Monte, Regal, and GN sites that will have that info. Those cars weren't that much heavier and had basically the same rear ratios (some were better).

After i finish studying for my 2 finals tommorow, and writing an essay for a scholarship i will check that out, and report back with my findings. I am just as interested as you to find out the basic specs of that car.

EDIT OK, seriously this is like NO info on these cars whatsoever. I was able to come up with a roughly 3535 lb. curb weight using the specs of an 83 hurst olds, and i was able to determine the 150HP and 240ft. lbs torque from the Lg4s of 83 firebirds. But i think that is as much as i could get. I would venture a guess and say that finding the rear end ratio would be nearly impossible, short of jacking up his car and looking for myself.

just a few. I know people have more links. They made millions of these cars and they are very easy to make fast.
