NEED ADVICE/OPINIONS

[Cryals]

I need honest opinions!!

I have a 78 fj40 and it has the 2f with stock 4spd trans. My goal is to get it to drive somewhat “modern” like be able to cruise at 60mph+ and not have the engine scream at me.

I have debated doing a 5.3ls swap with stock 4spd trans

I have debated h55f for overdrive (still stock engine doesn’t give the output)

This vehicle will be used as a cruiser and would like the option to be able to drive it across state going faster than 45-50mph and to be able to go up grades without getting tired. Would also like to be able to go out in the mountains with it.

Seems like everything I want out of it comes from V8 power but also Chevy doesn’t have to be the answer, it’s just the cheapest and most readily available parts. I would also like to be able to get better fuel economy.

I’d love expert advice here

I think an overdrive is the ticket NV4500 comes to mind. I was going to do a hand built 283 corvette engine (flat tappets, big valves, better cam...) Not an aluminum head/block person or fuel injection. I don't mind adjusting points, valves, carbs.

You should the tons of build threads to see what people have done to their rigs.
I think it would be cheaper to get the FJ Cruiser with a 6 speed manual

5.3 with an overdrive is the way to go if that’s what you’re looking for. It will still scream at you but at least you can scream back.
There are plenty of threads on here with the LS series plus 5 speeds or the 4L60e. I run at about 2000 rpm at 65-70 with 33’s. Gas mileage has improved to 16 to 18 mpg at highway speeds. I’m running a 5.3 LM7 plus 4L60e.
With the stock 2F and 4 speed you could bump up to a taller tire and rubber overdrive it. I ran an F.5 and 4 speed for years with 33’s and it drove pretty good. Until I seized it up. That’s the only reason I went with the newer combination. The V8s are a hoot to drive but you lose a bit of the FJ40’s soul.
