750HP Take a ride -1979 F150 4x4 - In cab view

Crowd Really liked it. Seems like a lot of people have had an old Ford truck at one time or another. The people running the racing wanted me to keep racing.

On Wednesday's at Portland international raceway they have a car show cruise in going at the same time with all kinds of cool rigs and bikes and live music.

Parked after 4 runs and had some food and entertainment.

Drove Truck to work in the morning to race track then happy hour and home. 60 miles.

Time for some suspension work. I found the front driver side tire had cut up the inner plastic fender while racing. Watched a video taken from the outside and the front driver tire was 'bobbing' up and down for part of the run. I have a 4" inch lift and must have some loose bushings???

750HP vrs 697HP issue.
Not here to argue dyno's and numbers.
Original post with the symbol "~" before 750HP means I think I am somewhere in the area of 750HP.
My opinion only, Based on:
1. 6% conservative dyno when compared to same motor's (dyno'd by Scott Johnson RHP aka mad porter) at his dyno and then engine masters.
2. Stud girdles were on wrong which Really tweaked the valves out of spec by up to 8 degrees on the wheel for several cylinders.
3. Major port blockage in the headers since fixed & ceramic coated.
4. Similar builds
5. HP from 1/8 mile calculators and the drag simulation program.
Also polished the exhaust ports. (no shown gains on the P51 heads n/a but who knows when the bottle turns on? figured it couldn't hurt)

I should bolt some slicks on!!!
somewhere around 5100 lbs race weight.
38 gallons of gas in the tank. I think it's time for a race cell; if I wreck with that it'll be a real BBQ./

2wd would be much easier to drive and a lot less drag with 1 less driveline and 2 less axles and the transfer case out of the equation. Front to rear ratios don't quite match up either in 4wd so the tires have to slip to 'catch up.' Bit of difference in tire height with more weight on the front end always binds and gets stuck in 4wd.

The cage install was a chore, try the link below for some pics and let me know if it doesn't work.
Cage main tubes from JEGs online. It is good for the NHRA but not dessert off road racing. Used 2x3 .134" wall frame outriggers to secure to the frame. Never realized how narrow the 79 F150 frame was until the cage install......
Narrowed the factory seat 1.5 inches to fit the cage and even kept the speakers behind the seat!
Added many gussets's and some grab bars plus a dash bar for extra support.
If I ever off road race i'll add addtional supporting roll bar to the bed.

Is the front Dana 44 all stock? I'm amazed it held together on a 4wd pass with all that torque off the line. The link worked for the cage, Thanks!

Playhard557, do you drive your truck on the road at all? Was curious how the spool worked out if you did. Did you keep the same u-bolt axle attachment for your L&L's? Don't worry about the front axle and transfer case, remember Pat's red Bronco? Still had the huge front aftermarket bumper and could pull the wheels

I pulled my stock 31 spline axles to take a look and was shocked how twisted the splines were. Now I'm kicking myself I didn't sell my locker and go with 35 spline instead of the 31 spline aftermarket.

If looking at shifters I have a B&M Megashifter that wasn't bad to work with but is getting swapped with a kwik Shifter I as soon as it arrives. The only down side to the Kwik is it doesn't have a reverse light switch but if you don't have a trans brake you can use that micro switch.

Thanks for the comments. Good to hear the cage link worked.

Someday if i ever get time, i will do a build-up post.

The rear glass I swapped with a piece of lexan. Used the orginal frame and glass to outline and using same thickness lexan. Went in real easy with the factory molding. Not any real weight savings maybe a few pounds.

Front end Dana 44 yukon 4340 axles, solid joints, gear driven posi, gold hubs. My second launch no power braking and quickly flooring it lit up all 4 tires to the point the front end was violently hopping up and down. Felt like loose sand. Quickly Backed all the way. I've heard the pinion is the weak point, maybe the hubs and the factory 1310 ujoints. ( i have loops front and rear)

Shifter is Hurst promatic with linkage mounted upside down and has been a bear to get adjusted. thanks for kwik shifter info.

Idle about 1000rpm and truck has about 100lbs of dynomat sound deadener in the the cab and is MUCH louder outside. Drives decent on the street with the spool but scares a lot of people when it squeals the tires just turning!!

L&L ladder bars are still installed per L&L instruction.

The role cage really stiffens up the old ford.

Took my 10 month old baby boy for his first ride last week. 20 miles round trip. He loved sitting up front, grabbing for the shifter and would look at me confused when I goosed it. Actually fell asleep on the way home.
