Yeah same here, once you pass you dont have to again for 10 years..
unless a cop pulls you over and gives you an inspection date.. than you have to go
or you answer to court....

i have a 740$ debt with the Association Automobile du quebec, too many tickets
and i have been pulled over a couple of times.. they were going to suspend my license
so i had to go to court for a paying arragement.. i had to pay 175$ upfront..
and the rest i am paying 50$/month for the next year..a$$es

A little off-topic, but how are they the asses when you were the one speeding?

aaaaaaahA!!

no speeding.. all pooozie offenses.

burning a red
u-turn x2
parking violations-plenty of these.. and different ones too.. old folk parking, handicap parking, not paying for public parking, and my favorite parking in a reserved for bus
lane downtown.. only for like 5 minutes, the cop saw me.. when i came back he handed me my ticket and said i wasnt allowed, and i have to pay it because im guilty. downtown parking is expensive and hard to find.. so its not a criminal thing.. its just that i dont like spending half an hour to find a damn spot.. or to park like a few block away from my destination

edit: the cop let me go for the red, because he didnt want to pull me over.. but everyone started honking at me.. so the cop had no choice.. instead he gave me a 95$ ticket for not having my car registration paper signed... he was a good man.

The asses portion was reffered to the court(*) and the AA, for not giving me a chance to pay everything monthly.. and they threatened me with a license suspension.. thats worthy of ***

How do you figure that? Where are you getting this info? If I would of made a comment like that I would of been getting a PM by now. Grand Prix GTs have 3.29 gearing stock. 3.33 is only a little higher then that. With 3.69 gearing they can still trap over 125 depending on shiftpoints.

You should also look into a higher stall to help you get into that new found power.

As far as power... If you are throwing in a cam you are going to have a higher powerband. Only why your going to be close to quick is to get everything to flow better and raise/spread the powerband.

you cant compare a L36 of a GPGT with a Bonneville L27.....the motors are totally different in the design and where the power is made..... there is no basis of comparison

my statement of the 3.33'* still stands, and others on this forum that have 3.33'* in there cars stock will agree

Ok small question won't he need custom PCM tuning to use the 3.33 gear ratio.

I agree with Pat. The L27 is very similar to the Series 1 L67 in where it delivers it'* power. The motor has no top end. This is due in part to the heavier rotating internals when compared to the L36. 3.33'* would be great off the line, coupled with a mildly modded L27, and it would be ricer fodder at any rpm higher than about 3k.

The older 3800 was not any good with the 3.33 gear ratio... The Bonnevilles that did have the 3.33 ratio were slower to 60 than the 2.84 and 2.97 equiped bonnevilles... Being a series I, I'd go no further than 3.06, even if modded...
