PURPLE HORONET

Quick story in 1987 the owner of the car took it off the road. He decided to build the car for the dragstrip. He tubbed the car, added a small cage, built the 440 and trans. Changed the gears. While working on the interior of the car he died. This car has been sitting for over 20 years under a pole shed and never made one pass down the track. I hate to see it tubbed being a R/T but he did a super job. He did not cut the dash. Still has the factory 150 speedo buckets and console.


Here is what I am starting with,,,

PURPLE HORONET

Plans for the car nothing show worthy,, Its going to keep the old school drag car look,, and the look that it was just dragged out of a pole barn. Its going to be loud and sound nasty. I will run the tunnel ram a dual quads..

Coronet 500

Super car. Nice that you have all the chrome and straight body.

welcome
nice find, it's funny how life brings us thing's..

PURPLE HORONET

Pulled the engine and took it apart to see what was in it. 69 440 HP with 906 heads. I guess I can throw number matching out the window..

The engine looks super inside.. Forged flat tops, steele crank arp rod bolts with new rods.. Plus the engine was balanced.. I dropped the heads off at the machine shop for inspection. I also dropped the crank off to be polished.

Looked like 2 lobes on the cam were fixing to get smoked.. The blame like 99% of the time improper valve train set up. It had some kind of double springs that seemed to be for some kind of 700 lift cam or bigger . The cam lifters and springs headed straight for the trash can.

PURPLE HORONET

Stripped all the wires out and threw them in the trash also. Just like most 67 cars they were hard and spliced everywhere. Pulled the wiper motor and made a block off plate. Here is a pic of the size tire thats on the back... I will go with the same size but a street tire.

PURPLE HORONET

Dug up some phone numbers of some old mopar connections and their still alive.. The hood they cut for the tunnel ram was rusty. I found a original white paint basic coronet hood that was stored inside. I still have the original R/T hood uncut.

I also found a basic 120mph dash to cut up for my gauges. I did not want to cut the factory 150mph dash. If you notice the 11000 rpm 3.5 inch tach with recall. This tach was never sold to the public you can only buy the monster tach that goes to 11000. It was sold for use in Nascars,, I bought a pile of gauges that were take-outs from a Nascar.. They use them in one race then change them.

Your flat tappet purple cam still needs that zinc additive for the cam lobes.

PURPLE HORONET

I did not build the engine the first time, and I am not the one that smoked the lobe or put the wrong springs on. But I will be the one that corrects the problem LOL...

What a great start to what looks like an awesome project!

MReeves

I have a good friend that has a 67 RT that many years ago took it off the street and raced it and has sonce put it back on the street for those special Sunday afternoon rides....

Skwerly

COOL! That beast is awesome.

PURPLE HORONET

Got the block an crank back from the machine shop.. All good the block is 30 over and was decked 30 also by the previous owner..

Being their was only a couple of hours of run time, a quick dingle berry hone was all it needed, I also had the crank polished.. The crank is 10/10.


Tonight I installed the freeze plugs, cam bearings and crank.

PURPLE HORONET

Now for my engine build parts that I am useing...

30 over trw forged flat tops after the what was decked, and heads worked
the comp. should be between 9.6-9.8..

Steel crank 10/10 turned on the low positive side,, gonna run a high volume pump and a Mopar 8 quart pan.,, Should turn up real nice.
Everything has been balanced also

NOW FOR THE FUN STUFF,
being this is a tubbed street car with a roll cage its got to sound nasty, Not my cam of choice to run every weekend at the dragstrip. But a fun street cam.

Comp cams Hyd. BIG ***** THUMPR good for 2500-6400
All comp valve train
Comp springs 911-16
comp magnum roller chain
Comp ultra pro Magnum adjustable roller rockers

PURPLE HORONET

Love the comp stuff, always use their kits.

PURPLE HORONET

Got some goodies today,, Mopar Performance 8qt pan,, pickup,, and bolt kit,, Comp ultra pro mag adjustable rockers and comp mag pushrods
and Mopar valve covers with polished sides and baffles.. Plus I got my heads back.

Gorts 5th

love that rocker set i need one!
Are you going to polish those heads maybe some porting?

PURPLE HORONET

The heads have a little port job done, gasket matched nothing trick. Just going to run it the way it is. Ebay is the cheapest
place on the rockers, saved 40 bucks over sumit

PURPLE HORONET

Got to work on my engine tonight,, One of the biggest reason I am doing this project is my son said he wanted to learn how to build a engine. So I am showing him how to do everything.. Not bad for him being 19 and want to hang out on saturday night and build a engine. Plus thats after working from 6am till 3pm, then band practice from 4 till 7 then engine time from 7 to 12..

Everything went good tonight just 2 problems.. The pushrods are to long.. I took a gamble and bought the stock lenth.. Also the oil pickup for the 8 quart pan is the wrong thread size..

TVLynn

There are two thread sizes available. The standard 3/8" and a modified larger 1/2" Hemi size
both pipe thread.. Check with the pan mfg.. So you may want to drill yours out and re thread BE careful The angle needs to be correct

PURPLE HORONET

I goofed up I got the 1/2,, I have been buying parts from summit for over 20 years and never had a problem.. I called their tec line and they could not tell me what oil pickup I needed or what pick up went with that pan.. I got the pickup from jegs an the pan from summit. Plus summit did not have them in stock...

I belive the push rods I need are comp 7402-16 8.555,,, I have the 9.295 and their to long.. Friends bringing by a tool so I cam measure what I need.. Summit says ship date 3-1-13 on them.. Guess they will loose another sale from me.

PURPLE HORONET

I am not going to drill to much of the engine together,, From what I researched I need the Mopar 5007817

PAN 5007816
3/8 5007817
1/2 5007818 That what I got

TVLynn

PURPLE HORONET

Cant catch a break, went to stick my pushrods in that my machine shop got for me and their wrong, their oil threw pushrods. Should have used your link

challenger

Looking good bet ya' cant wait till its all done Keep us up to date

TVLynn

The optimum word is custom ! So there are bound to be things that need attention / fitting during the build..

PURPLE HORONET

Talked to a couple of people today even comp and they said its fine to run the push rods with the oil holes.

Catamount

Were you able to get the dead body smell out of the interior?

Wow, a lot of work, I wish I had your mechanical ability.
