All Small Six Cost of Building a 250ci VS 300ci

simple way the '61 kept the 4 LUG - SIX 'look', while upgrading to beefier front suspension and steering was to use '71 Maverick six 4 LUG spindles. AND - matches a bolt-in 8" Maverick 4 LUG rear.

Maverick 4 Lug spindles accept the popular "Scarebird" type disc upgrade as well.

About the same power as a 351C. Is that too much?

As far as I am concerned, all new performance 300 sixes are built with roller cams. No flat tappet cams.
You can have a streetable 350 hp and 400 lb ft of torque with a N/A 300 six.
It is not a budget build by a long shot.

You will need a Ford 9" rear to handle the torque.

The truck is using a 10.25" sterling rear with the larger yoke for larger "U" joints.
The engine also requires a torque strap to keep it from tearing the motor mount on the driver's side.
This is because the truck is pulling in a lot lower gear than a car.

They wouldn't happen to make reproduction spindles for a Maverick would they? I am a total idiot when it comes to the basic concepts, so this might be a stupid question. But why can't you use the V8 spindles and steering from a first gen Mustang with the 4 lug braking system?

I would have to work on a budget for sure. But as I saved up money, I could make the necessary upgrades to achieve that amount of power.

So, it looks like I need an alternator, carburetor, radiator, and a new throttle linkage for this 250ci. Would it cost much more to get a complete 300ci?

And we forgot to mention the additional weight that is put on the front end.

Also, oil pan mods and header selection may not make for an easy swap unless you can weld and do some fab work. Also, the Crossflow head from Oz or the head from Matt Cox may give the 300 a run for its money. Back when the Hotsixes forum in Oz was up and going, one of their top head porters down there on that site was getting 450 HP out of 250's with no roller cam or turbo and was street driven.....

Are these what I need?
