Hello all here is my project, me and my wife have owned it for around 3 years after we brought it as a part built project.

It is a fiber glass body on a boxed and shortened dodge d100 chassie, straight front axel. The car has gone throght after changes since we have owned it. Here are a couple pics from before we brought it and when it first arrived with us.

It had a 440 low comp engine with a tunnel ram and twin holley 660s to start with, ignition was taken care of by accel coil, 727 torque flite, and a 9" ford rear end with a spool . 9" was mounted by chrome ladder bars. The front was a straight axel on leaf springs with ford transit spindles and brakes..

8 months after arriving at ours the car was ready for its 1st trip to the strip. At this point we found out the issues we had with the car. 1st we thought we had care issues so fitted 2 new holley 600 carbs. We later diagnosed the issue down to a faulty dizzy so the accel was replaced with a full msd system. The open single pipe heads went to for a custom set of headers with cherry bombs. We also fitted headlights at this point too. We then headed to strip again, this time car run along better but after lot of messing with the carbs still couldn't get it running 100%. After may hours on Internet I came across an article about balancing vac secondary with a balance tube, so In went an order for 2 spring kits and quick change tops. Then we headed back to the track. The car ran best it ever had running p.b of 16.01 @82mph. At this point we made the choice to put car away for a year. (This was end of 2019 be we know moat people wouldn't be out in 2020)

Original plans for car were to have a mild build involving new pistons to up compression ratio, new heads and a general refresh so we pulled and stripped the engine down. One day sat on Facebook and a friend tags me in a reconned 440 block with fully forged rotating assembly. 48 hours later the block was in my garage. Now a mild refresh is a complete engine build. This is the first engine I've ever had built but instead of getting someone else to get the parts I wanted to spec it so following many hours of reading reviews and reading up of technical stuff I ordered the parts over a 2 month period, then found a builder. Only issue he ran into was I ordered incorrect cam bolts. Only thinks I left for engine builder to order was main bearing, piston rings and push rods (this was because I don't have tools to mesure)

The next issue was will a 727 that the power then new engine has the potential to make, simple answer to that was no. So in the middle of country wide lock down the gear box as loaded on a pallet and shipped off for a rebuild.

Next decision was to weather keep the tunnel ram or uses the single plane we had. At this point we had a tunnel ram, a tonker 2 and a trick flow manifold. We choice the trick flow meaning we needed a new carb, we choice to go efi root. After more hours of research a holley sniper x flow was ordered with a new billet regulator and fuel pump. Then the msd system was sold to as we have some for a hyperspark system to compliment the xflow.

Next was the need for a brake upgrade. Unfortunately we couldn't find anything to fit our spindles so new 1929-1948 ford spindles were ordered and some big 6 pot willwoods.

The front wheels have always been shelby cal 500 with white wall tyres, the rears are 9" slot mags that had slicks.on then replaced with hoosiers. The 9" slot mags will now be used as road tyres as we have got a set of 11" shelby for the rear with mickey Thompson et streets.

The next question i needed answers to was what spline are my rear half shafts. I pulled them to find out they are 31 spline but had a weird ware marks this lead to the 3rd.member being pulled only to find out that none of the 4 bolts on the main caps were tight. So now the standard 9" rear end is going to be replaced with a hd pro alloy third member hosing a strange s track and 35 spline half shafts all housing in a new braces housing.

Been 2 busy weekends, the body and chassie is now completely stripped of everything other then master cylinder and steering column. All ready to got to the fabricators for new 8.50 tagged cage and new strange rear axel and wheel bars. Also we have cut the rear out in preparation to tub the rears for the new wheels, I have test fitted them and they fit just how I wanted them too.

Hey Austin

Want the stance to look like the hemi hauler with similar wheel bars too.

Also we have decided that the low back seats we have are just to kow so will be switching to a set of jaz low back prostock seats. Also changing the red steering g wheel to a similar design but in back with quick release to make it easy to get in and out of.

Man, that looks like a very nice gasser! If I can say, I agree that the rear fender looks like it does curve inward toward the face of the wheel. I see it in several photos and it does appear that way. But I don't see the same effect in the blue car's rear fender. Just saying,

Maybe its me..... but the curves look fine on the rear tires. Smooth curves as a visual.
