"RV cam" with '70 timing set in an '86 carb 460

Is this a feasible setup?
On an '86 carburetted 460 in an F-250, install an "rv cam" and an early (stright up 1970) timing set, and drop the motor into my '66 F-100.
I have a '77 460 with D3VE-A2A heads, but it has a badly spun bearing.
Thanks for any input.

Sure it's feasable, it's what I run in my '86. DTD says that it makes around 360 HP and 500 lb/ft of torque. Most of the time in the dry, I have trouble keeping the rear wheels from spinning(lead foot), but we got a real good rain storm today, and driving like an egg was under the pedal, I couldn't keep from spinning the tires across intersections and going up hills. Without a kickdown, and staying in high gear, I timed a 40-75 top gear runn, and got a hair over 7 seconds. It has plenty of go, but even with 3.55's, it drinks gas like it's going out of style. I think it's because of the carb, more or less, so, next week, on goes the 600 Edelbrock. Good luck.

ThereGoes... you might consider EFI if the fuel drinking is irritating. While its a lot more work to tune and adjust to your hardware, the mileage is nicer and the consistant starts rain, snow, sleet, hot, cold, dry whatever, is a good thing.

But then again, my concept of tuning a carb is to beat it with the biggest pipe wrench I can find. I've never had good luck with carbs. Except for the Predator. I like how it just bolts on and tunes itself. That's more my speed

Frederic,
FI is way outta the budget($6.50/hr, $97.00/mo for insurance, and $100/mo cell phone bill = no money for fun) and the Edelbrock is actually the easiest carb I've ever worked with. Sure, it's nice, but with a good choke(or even a not so good one, as on my current Holley POS emissions carb) it fires right up. And, when my dad switched from a very well tuned Holley 500 2V to the Edelbrock 600 4V, he picked up an honest 2 MPG, which, in town, would put me at 13-14, and on the highway, 16-17, maybe more if I baby it.

Well, converting to EFI is expensive if you buy all the parts new, and pay someone to install it for you.

I'm a cheap, er, frugal kinda guy so the EFI for my 500cid twin-turbo stroker cost me zero. I simply bought a junkyard running engine, tore off the heads and the EFI bits, power washed the block and heads, and sold them individually on e-bay. My net cost for the EFI bits was -$117 according to my notebook.

Not trying to sell you... merely suggesting a little resourcefulness might be in order if this is actually a consideration for you. As you save funds over time, you can actually buy tuning tools for EFI and do some fun stuff too.

My 1975 D200 Dodge pickup went from 7mpg (yes, SEVEN) to 17ish mpg on the highway, if I was very gentle with the throttle, after converting to EFI. I had to be gentle with the throttle because I swapped out the 318cid for a 451 twin-turbo stroker. So if I was gentle, I got nice mileage before the turbos went "happy". Of course I could get 1 mpg full throttle in any gear... just had to snap the pedal to the floor and hold on.

But again, I'm very biased, and i'll freely admit such. As I said, I've NEVER owned a vehicle where I got the carb right... used, new, holley, edelbrock, etc. I tried them all, and was miserable. Except for the predator, that carb I could tune. You just bolt it on and not think about it again ;-)

Anyway, I've diverted this thread... my apologies.
