I have an 81 Toyota pickup with a 22r from a newer truck. It had a troubled 350 in it pulling 37s. Finally got it all buttoned up with the 22r and 5 speed trans, and with stock tires it drives like I’m trying to pull big tires. It has 4.10 gears (from what I was told) and when I drive it, I can shift 1st and 2nd and if on flat ground 3rd and if down hill 4th and 5th. Could it be timing issues? Or a shotty trans? Carb? I’m not sure. Any help would be greatly appreciated

 

May sound too simple, but have you checked all the fluids? If you're down on oil and/or trans fluid it'll definitely make it feel sluggish.

 

All engine fluids are good, haven’t checked the trans fluid in a bit, maybe I’ll give that a check. Imma kick myself in the a** if that’s the problem.

Although, I adjusted my timing and With the distributor all the way turned the closest I can get it to 0 is between 8 and 5. Runs a lot better than it did before adjusting, but still a little sluggish.

 

It's worth a try. I know whenever my Jeep starts slowing down, it's time for tranny fluid lol. Timing is definitely a big part of it as well. When my mechanic put the new head on he had the timing cranked way up which made it feel less sluggish, but it wasn't right.

 

I’ll try that out in the morning. Thanks for your input, appreciate it.
