long bed 61 truck

Im working on a project building a 1961 C-10 fleet-side long box. My truck will have a 454 .30 over mild cam and a 750 carb. I noticed a lot of short box trucks on the track and not that many long beds ! Is there any reason for that outside of the look? Is there any problems racing long-bed trucks ?

I am not a racer and do not know much about building something to race but I would think the long bed would have less weight transfer to the rear wheels as a short box. It would also have a longer driveshaft so you would lose a little bit of horsepower in the longer driveshaft, I think. The frame would also be longer so wouldn't it be easier to twist or something like that and make it harder to steer. These are just thoughts of mine, like I said I am not a racer.

Is there any reason long beds aren't good for drag racing compared to short bed trucks?

A coupla things off the top of my head, weight distribution, drive shaft length, getting the back half to hook up, extra weight. I've seen a few done this way tho, they can make a good looking ride. where in Ca. are you located? Try to go to one of the nostalgia meets at Famoso, everything under the sun runs there. Dan

Less weight by percentage of wheelbase on the rear tires, and they just weight too much. Weight is a killer in drag racing, 300 hp in a Pinto(2400 lbs) is fast, 300 hp in a longbed truck(4200 lbs) is a slug. Because of weight the truck would need more than 550+ hp to equal the performance of the Pinto with 300 hp

LWB trucks have the problems associated w/weight, weight transfer and aerodynamics.

But, OTOH:
  • They're super easy to tub
  • They will fit any engine (for all practical purposes)- including a big radiator, tall intake, turbo plumbing, intercooler, supercharger, etc.- w/o even a hole through the hood in many cases
  • The frame will take almost any amount of HP/torque
  • They're cheap
  • They're easy to work on
  • They're readily available
  • Lots of parts in the aftermarket and 'yards
  • They're useful when not being raced
  • And done right- can be damn fast
IIRC, the very first year one of the car rags ran one of the "promotional" race classes like "worlds fastest street car", "muscle car shootout" or some such deal (before it was bought out and promoted by other entities), one of the quickest "cars" was a nondescript white Chevy truck!

Granted, it was surpassed due to the class rules changing, along w/the class itself maturing. So by the next year, it was no longer as competitive against more race-orientated "street" cars.

A trip to the drag strip will reveal there are a LOT of racy trucks out there. A short box would be preferred, an S10/15 is lighter, but a little more difficult to package, but- generally speaking- a truck can make a killer dual-purpose racer/driver, IMO.

In all my years of hanging around a drag strip, I remember only one long bed Chevy truck that ran well (8 seconds) consistently. It was fully caged (14-point with Funny cage) and ran a blown BBC. I haven't seen the truck for maybe 10 years now, don't know what happened to it.
