Default Grand National internals

I have been thinking about this for some time now, but as I said before, I'm new to these motors. I have looked over a couple of GN motors at various meet ups and shows in my area. I have noticed while looking them over, from the heads down, they look ALMOST identical. So i did a little more looking into it and was told that the heads are the real difference. The reason I am so interested in the GN motor is, well, they are known to be capable of being monsters. Furthermore, unless I'm just out of the loop, I can't really find too many aftermarket block internals (crank, rods, pistons) that are much better then stock. My "pipedream" is to see a series one break 9'* in the 1/4 mile, frontwheel drive. Oh yeah, and be streetable. I'm open for your opinions and facts.

To hit the 9'*.. and be streetable.. Is in my opinion not possible. For that matter.. how many cars do you see that can do a 9 second quarter and still be on the street? There are very few.

If you are looking for parts.. S1 parts are probably going to end up being Austraiian. They have performance parts.

Now..if you want to build a monster and might consider an S2.. talk to Intense and ZZP.

You're not going to hit 9'* in a S1 without about 10k in the motor, and at LEAST another 5k on the trans. You can build the motors to hell and gone, and the stock internals wil take you very far, but the trans is going to be your weak spot.

I think you'd get off cheaper converting to RWD with a GN motor and trans.

well, I didn't say " I " was going to be the one to put the series1 in the 9'* and be streetable, I just said I would like to see it happen. I know this isn't the same but in the import world, the american version nissan 240sx came with what everybody called a weak truck motor, the 4de, so many people were dropping in the japan version sr20det. Now there are guys breaking 9'* and 8'* on the 4de, and keeping SOME of them streetable, and those are times sr20det'* could only dream about. My point is, yes I know the cost can get outragous, but I'm all about the underdog. People near and far tell me that the series1 is a weak thrown-together motor, but I think its potential is far more then that. I've had enough fast cars in my life, import and domestic, but for some reason I haven't liked ANY of them as much as this car. If my memory serves me right, the fastest I've seen a series1 Bonny posted on this site is low 13'* with spray, my goal is atleast 11'*, but I need help from you GURU'*, like I said, this motor is new for me.

im with you here. I feel if you go with some aussie internals and a turbo you could push some serious numbers and be in the 11'* or 10'*. I would like my 88 Lesabre T-Type (LN3) to be in the mid 12'*. But i have got to save up the money because my engine is mostly stock and there are a ton of supporting mods that would be needed along with a well built 4t65-e from intense

Sorry to thread jack but do you know of any websites for the Australian parts for the S1?

There are many others if you do a google or yahoo search on Holden 3800 or Holden V6.

Bear in mind, their Series designation is different than ours. Our Series 2 is their Ecotech. Our Series 1 is their Series 2. You work backwards into their V series to hit the LG3/LN3.
