52 F-1 weight before and after

Since I had Belle's weight before we started work on the new engine install. I thought I would take a trip over to the scales today and how much has changed.

Weight before was a stock V8 truck with aluminum wheels 215 tires and a Ford nine inch rear-end.

The rebuild added :
Ford Coyote 420 HP engine and Tremec 5 speed.
Independent front and 4-link rear suspension with coil-overs.
AC, PS and power brakes.
215 front and 255 rear tires on steel rims.
Boxing the front half of the frame and adding additional cross-members

Weight before with 5 gal of fuel 3180
Weight after with 15 gal of fuel 3340
Subtract the weight of the additional 10 gal of fuel (60#) for a net gain of 100 pounds.

Weight on the front axle was 1940 pounds for a front to rear weight ratio of 58% to 42%. This was done with no passengers but since the wheelbase is 115" and the distance from the front wheel center line to my butt in the seat is 57" passengers wont have much effect.

Cool. That is actually a much better weight distribution than I would have thought. Your truck is the ultimate sleeper.

Hmmm! Maybe you were using the new core math method or my calculator is broken, but mine says 42% rear and 58% front?

I just re-calculated and you are correct. Don't know what happened but those figures make much more sense to me. I will correct the figures.

That truck is gorgeous! Bet it doesn't sound like an old flathead under that hood.

I'm surprised at the "new" weight too.

Flathead vs Coyote -- without considering the A/C components, I wouldn't think there's much difference. The Coyote may be aluminum, but there's a lot of it, 4X the cams, valves, etc.

Tremec vs stock trans - maybe a wash; was it a 4-sp truck? If so that would explain at least 50 lbs.

9" vs (8.8?) -- 9"ers are heavy for sure. But you added the links.

Did you have a stock spare, and one now?

But with the P/S, A/C, new seats, even the steering column, I'm surprised you aren't a lot heavier now. Do you have the old F/R weight distribution?

I always wonder how accurate those scales are down this low. Was it a commercial truck scale? Something used for 40k lb loads may not be real accurate at the lower end.

Truck stop scales are usually calibrated and legally certified (with a sign posted indicating they are). Therefore I would expect that the margin of error is small throughout it's range. If you need higher precision, many race shops have 4 platform scales for doing corner weighting accurate to < 1#.

My specs show the Flathead at 565# and the Coyote at about 480# with starter and alternator so some weight savings there.

Tremec vs stock trans - maybe a wash; was it a 4-sp truck? If so that would explain at least 50 lbs.

Old trans was a 3sp HD don't know weight. Tremec is 100#

9" vs (8.8?) -- 9"ers are heavy for sure. But you added the links.

Truck already had the 9" but I removed the leaf springs and added the 4-link.

Did you have a stock spare, and one now?

Spare is gone now so I save that weight. 70#?

But with the P/S, A/C, new seats, even the steering column, I'm surprised you aren't a lot heavier now. Do you have the old F/R weight distribution?

Re-used the old column and seat and unfortunately don't have the old F/R.

They sell materials to the public so the weigh pickups on the way in and again on the way out so as Ax says they are controlled by weights and measures. Would think this is pretty close, I have weighed several vehicles on their scales and it has seemed very consistent with expectations.

Congratulations on the new truck. Please share your progress with us.

It doesn't sound like it or feel like it! I love my 56 Fairlane but have to admit, it is fun when I get to drive the wife's truck.
