what do you call the beast? a chevota or Toylet?
What part of Canada is winter 8 months? The 400 is a decent engine and if the person that built it used good parts then,drive the wheels off it

I know you did,but I dont know the OP so I should behave.
There seems to be quite a few land cruisers with sbc conversions and a bell housing is available to use the Toyota transmission

TH350 with 1.0 3rd gear, 38" tire, 4.37 rear gear, 2500 rpm's = 64 mph.
TH350 with 1.0 3rd gear, 28" tire, 3.25 rear gear, 2500 rpm's = 64 mph.

TH350 with 1.0 3rd gear, 38" tire, 5.71 rear gear, 3250 rpm's = 64 mph
TH350 with 1.0 3rd gear, 28" tire, 4.18 rear gear, 3250 rpm's = 64 mph

If you used a 28" tire and a 3.25 rear gear, you would make the same speed at the same rpm's that you would if you used a 4.37 rear gear and a 38" tire. Now, if your truck did have 28" tires and a 3.25 gear, you certainly wouldn't install a "big" cam and expect it to perform correctly. You would add more gear. Let's say that you changed out the 3.25 cogs for a set of 4.18 cogs in order to "get up on the cam". I'm fully aware that there are no such cogs available for your differentials, I'm just crunchin' numbers for you to show you that you will need more gear with those meats. In order to have the same speed and rpm as you would with 28" tires and a 4.18 gear, you will need a set of 5.71's front and rear. Yes, that is a real gearset for a Toyota differential.

You don't have enough gear to run a "big" cam.

A SBC toyota with 38's wont need 571 gears unless its a "mud only" truck. Also the 529 and 571 gear set's are known for tearing up the gear sets. 488 or 513 ratio should work well.

If you use a toyota transfer case then gears do not matter for off road as you can stack them and low range is 3:1. Just worry about whats good enough on the street
