What's my motor?

[MontanaFJ40]

The block is back from the machine shop and at the mechanic shop now, but not the head yet. I'll have your questions answered soon. I am really impressed with all of the interest and suggestions from everyone. I'll keep you all posted shortly after i know. Thanks!!!

I have confirmed from a couple of different websites that the motor is a Chevy 2

50 cu in.

Now to try and find out what model it came out of. It might help for buying parts.

The cylinders are 100 mm diameter.

Awesome. Your model is 'Chevy 2?' It is also known as, 'Nova,' for the later years. My mother had a '68 Nova and it was one of the first cars that I worked on. I believe that you have a cast iron intake manifold. Toyota manifolds that are not cracked are harder to find than Fs or 2Fs, in my searches.

I'd totally go with a GM 250 in my rig if I didn't have a couple of Toyota drivetrains laying around. They come up all the time on Craigslist. There seems to be a robust aftermarket for them. People ignore their ability because the V8 has an even greater appeal. But, for me, a 250 straight 6 is the primary non-Toyota option that I would run in a rig.

How many gears does your transmission have? A Muncie 420 465 are native to that motor / clutch when used in GM trucks.

You might need to look into high-elevation carburetor options, or electronic fuel injection, for the good performance wheeling in your region.

I know the Chevy ll pretty well. They were really popular when i graduated high school in 1968. Do you feel fairly certain that's what this motor came out of? From what I've found on the Internet they were used in a wide range of vehicles including Chevy, Pontiac, Buick, Olsmobile as well as trucks. Thanks for the info. Oh, my FJ40 is a three speed on the floor.

And of course No Va is Spanish for She doesn't go...

Could be a Camaro? El Camino, Implala, Chevelle, Bel Air, C/K, Biscayne? Is it cilantro, or Chinese parsley? I can't support or challenge it.
