I'm excited! Hope to get my car in the 10's

What type of engine build do you want it to be? Track only, strip/street or street/strip! Good luck with the build !


I'm all excited about mine, I'm trying to plan things out and buy everything I need ahead of time but I'm sure I'm forgetting something or buying the wrong parts.

Strip/Street. I had the 429 in for 7-8 years only 500 miles maybe, mainly strip.

Pics Please...I am a big 69 Cougar enthusiast

lots of upgrades to help on the launch..but heres a video

that 1050 aint gonna be enough.. id do a 1250 dommy..
on the other hand im glad to see someone else using the tfs 325's. ive got them to replaced a set of blue thunders I torched. good luck.

No, it ain't going to do it you should sell the car to me

Just kidding, thanks for the quick reply on the vid, I miss my 69 Coug's... are you holding something back the video showed an 11.42 not 11.90, the stroke is going to add a ton of power you should be excited it will be a totally new car when you get the new big inch motor int it! Might have a 9 in you near future...how hard do you hit it out of the hole?

That was my second nitrous pass ever. First one I lost traction about 60ft out.
Ran a 12.2 on the only na pass I did that day. thats was the first time I raced the car in 4yrs.
That was a 150 shot

I will go out there and guess you are running somewhere in the neighborhood or 11.5x28.5 tires...I have no idea what rear suspension is in the car (can't see much with the wall in the video) or how adjustable it is, but with the new engine build your suspension (especially rear) will be like it was...on NOS...more hit all the way, torque is an animal. If you are running a stock leaf spring suspension you are going to want to look at that in your near future

You hit the nail on the head. Stock suspention 100% leaning towards caltracs.
I can't wait to see what it does.

Gonna put some 31 spline axles in it with a spool too.
Old car needs some upgrades. Got a 8 point bar as well

I bet that sucker it will run 10.90's in Noble on motor. Provided you can get it to hook.

I have some valves you can send back too.....

Not the ones coug said to stick up your ass?

Btw sorry bout your thread Shane, im sure a mod can clean it up

From the picture it looks like a full interior XR7 with factory tach, and factory air...Nice
I see you are also running the stock shifter, you will want to lose that...you may be able to keep the handle though.

Thanks it's A sports special a dealer add on, door trim and bullet rocker panels. I put an old Sun tach in it,
Heck, it still has a knob kenwood radio and 6x9's. Plan on transforming it over to more race car. Loosing the
A/C behind the dash radio ect.. Been workin on it this evening getting the 429 out

Got the 429 loaded ready to go!

Making any progress?

My 325's came in today. Can't wait to compare them to the 290's I have at home.

Yeah I made a little progress, Switch from power brakes to manual, took the interior out, and took the cougar over to a fab shop in Owasso for roll bar and shock tower notch. Got alot of new parts. Got a Front plate from Keith Fulp.
