I have a 1.9l Isuzu 4cyl out of my 1982 Chevy S10. It ran and drove (as seen in video below).
It has 250 some thousand miles.
I also have the 4speed that came behind it complete it shifts perfectly and has the clutch, throw out bearing, and anything else you'd need to mate the two.
Both were pulled from the same truck (i took the engine out and dropped the trans out the bottom which is why they are apart) so they both work together and i have all the hardware for them.
I can post pictures and videos of either/both as requested.
Thanks in advance for checking it out,
Gabe
