I took my '79 to the drag strip... had around 88k miles at the time, mostly all stock... she ran a 17.5 @85mph

So, as long as you're going more than a couple hundred yards, either one of you could win. Race safe, please.

Thank you for being semi-serious about this. I know racing an HT4100 is laughable. Do you know if it will mess with the censors or computer at all?

And to those showing concern about my poor motor, i appreciate it, but i doubt im going to blow it. I am rough with my car at times. I often get on it HARD,not to the point of \"abuse\", but i dont treat it like an HT4100 should be treated. It has NEVER given me any problems at all,never hinted at overheating,never had any weird noises, has just purred like a kitten for the last 30k miles ive driven it. Oil changed every 3k-4k. One or two drag races isnt going to blow it up. Or maybe it will,just an excuse to get a second car and park the Brougham so i can start to restore it.


In all seriousness though, please refer to the first post in the thread and reply with any helpful info. Thanks again guys.

Hey Passover, wanna drive down here and drag race me before I get rid of the car?

180 hp 88 brougham vs. 180 hp 89 brougham.

My autumn maple firemist paint will make mine faster though because it is faded and some of it has come off. You still have all that heavy a$$ paint on there.

If the 307 would beat the HT4100 off the line... I honestly don't think the HT4100 has enough HP in the mid-upper rev band to then start pulling on the 307.

If anything, I thought the HT4100 may have the jump due to gearing... but I guess the decent low RPM torque of the Olds engine may get it off the line pretty well.

Not at all. Racing 2 well matched slow cars is just as much fun IMO as racing in 2 fast cars. The race element is still there, the desire to achieve your goal is still there and you will still have a good adrenalin rush if its real close. When I had my '99 GMC Conversion van I raced my buddies work van (not sure what year but it had a 5.4 liter Triton motor and was a Ford). I beat him and I had fun doing it.

3.42 x 200 = 684.
2.56 x 255 = 652.8.

Even if the shape of the torque curves of both engines was roughly the same, the Brougham would still win. There just isn't enough from the 4100 throughout the powerband to win. And since the Fleetwood only has 5 less horses but 55 less foot pounds, we know that the 4100 hits peak torque at a higher RPM than the 307 does. The 307 has this race.
