I'm not super savvy, but I would like to do this right. My 1976 Toyota Chinook's 20r gave out, and I'm having trouble finding a replacement. 22r's (pre '85) seem to be a lot more affordable, but I'm having a hard time wrapping my mind around exactly what modifications would need to happen for the swap. I'm not confident enough in the cylinder head to play with the hybrid. My first dumb question is: can I use the 20r carb with the 22r engine or is an adapter enough? And I know I need an intake adapter, right? If someone could clear this up for me I'd be infinitely grateful. -emily
my first question is where are you?? and do you know what your chinook weighs??
yes, you need a 22R from a late 80 to August of 84 22R, I would highly suggest having the 20R head cleaned and checked out because a stock 20R head simply flows much better.
no, you do NOT want to use the 20R carb. it is only a 190cfm carb, you want to use a 22R stock carb or a weber 3236 which are both in the 300-325 cfm range.
the only dumb question is the one you dont ask
