    No contest Dude, you all ready win if your car runs as good as the parts you have in it!

    You're going to be in the mid to low 12s while the Cobra is lucky to be in the high to mid 13s and the '99 Camaro will be lucky to hit the low 13s, I am thinking you will taking there $$ if in they are dumb enough to bet! :D GL

    As long as you can get anything that resembles traction you shouldn't have a problem with either car unless they're sand bagging ready to push that 100 HP shot of No2 when you line up against them.

    Race the Junkstain first and just barely beat him so the Camaro doesn't chicken out. When you line up against the Camaro let both of them really know what your Buick is all about! Fun stuff, let us know how you do.

    You should slaughter the Mustang, they didn't get fast until the "Terminator" blown versions came out. The Camaro might be a different story, but I bet you still have it covered.

    You WILL kill both of those cars. By the time they get that thing rolling you will be way out front. Don't let Anyone under estimate the power of the 455. Both of them will be trying to beat you so badly they will be spinning their tires out of the hole. Plus they have to be able to shift those 5-6 speed cars. Bang second and say good bye.

    Come on, I run a 13.65 with a 355 Buick motor what you think now about that 455?

    I beat a Mustang that had a supercharger on it with my 125 shot of nitrous.

    13.9 Stang on slicks Ha Ha. piece of cake.

    If they run slicks I would say you should do it MT drag radials work great.

    Results! Buick ran a 13.7 mustang 14.4 Camaro didn't show. And half tracked an srt4

    Had a bad top end issue only gained 8 mph between 1/8 & 1/4 mile

    Feel the car should have been low 13 high 12 but guess the 455 don't push what I thought it would

    You should have picked up more mph than 8. What was your top end MPH. Might want to put your time slip info up. Lots of racers on the board that can jump in with recommendations.

    Perhaps fuel delivery is your top end limitation?

    Keep getting upload error but here is how it plays out

    .032 reaction
    I1-2.048
    I2-5.598
    I3-8.622 @ 80.47 mph
    1/4-13.772@ 88.591

    Car felt like it had no power after 1st gear did not want to rev, shifted out at 5500 valves started to float when I went through qtr in 2nd

    Think it's time to step up to an electric fuel pump, until today this car has never seen any loads except a few wot stabs and 1st and 4k 2nd gear pulls

    If fuel does not help,I would try changing the valve springs,you are loosing too much power at mid track.That's my opinion anyway.Bruno.

    Yes, that is a very low mph for a car in the 13s. You're either losing spark, fuel, or valves are floating most likely.

    Make sure the carb is opening all the way up, maybe the linkage is binding. I have seen that happen, simple fix.
