1979 Trans Am Test Speedo Shot

A 120+ mph run in our 1979 Trans Am with a 403 Olds Motor! Motor has been bored out .60 over with 9:1 compression pistons. Heads were ported, Edelbrock aluminum Manifold, Cam and carb kit, Roller Rockers and timing chain, Black Jack Headers and 2.5" cross over duel exhaust. Had the Trans rebuilt with a B&M Shift kit which got rid of the 2 second lag between 1st and 2nd gear to give a nice chirp and a 3000 RPM stall torque converter. The rear limited slip was rebuilt with 3.90:1 gear ratio done at my local speed shop with matching speedo gears and got rid of the original 2.41's it had . I was told not to waste my money on this motor by all my gear head friends, but I got the last laugh when it produced 395hp 433 fp of torque to the rear wheels on the Dyno. I got no respect when I bought this car back in 1985, but by 1991 it had beat everyone of them at New England Dragway with high 11's in the 1/4 mile on 295 60's street tires. This engine was blueprinted by Pro Steet Unlimited in East Hartford Ct back in 1991. I have made a few more additions since then which should put it over 400hp (I hope), but I haven't brought it back to the Dyno to verify that. There are no power adders on this either. I'm not looking for comments on this. I simply wanted to make a point that not every gear head knows as much as they think they do and it's easy to criticize when you don't have the knowlege or the facts. I look forward to meeting every one of them at a red light someday.

Cool video, I love that people underestimate our 403 olds engines. My TA ran a 15.8 in 1/4 mile when it was stock but with some performance parts and a 3.42 gears she can rip 13.9 sec 1/4 mile times. Thats not that fast for new musle cars but this one is 32 years old with 230,000 miles on it engine and transmission. Stop by my page and see my G-tech runs.

@Kingsalmon321 Nice Vid! I need one of those G-Tech's. Love your TA, I always wanted a black special edition. Mine was silver and I painted it Red when I started to restore the TA back in 1991. Right now mine needs a good refresh. You should bring it to the track sometime and have some fun. You might be able to break into the high 12's.

Did you changed your speedometer gears in your transmission, to match your new rear diff gear?

[tjscalora1]

@0122max Yes, I did. It was all done at my local speed shop. Pro Street Unlimited. If interested in the mods done, I have it all in the Comment under the video.  Just click on More info.

Do you have stock exhaust it sounds just like my 10th anniversary ??

[tjscalora1]

@IMHOSSBOSS No, It has Blackjack aluminum coated headers and cross over dual exhaust. The mufflers are actually Corvette turbos. It gives a nice low tone and not too loud. The cops used to stop me all the time when I had the glasspak's on it. I had also added cut outs just past the headers that I can open from the driver seat just before a run at the strip. The open headers gives a little more HP and can make are big difference at the track. The only problem with the cut outs is they can leak.

Why would you want to stop?
