Ok. So I know that 2Fs are not fast or super powerful but i'm wondering if my new '77 needs some help or if its just the way it is. It seems to run really well but it does not have the power I think it should. It has the hard top and 141k. It is in really good shape mechanically. And its all stock except for a safari roof rack and a 3" lift from SOR with 33x10.50 mud terrains and a vintage air system. The PO said he had the carb rebuilt by the toyota dealer in town and like I said it does idle and function quite well. But 50 to 55 mph is about all it will do comfortably and getting it to 60 is not easy. it also fades real fast when I hit a hill of any sort. Milage is also terrible at only 8 or 9 mpg. The reason I feel there may be an issue is that my '70 got 14 or 15 mpg and would easily go 60 and I still had plenty of room to go more. I just rarely did because it didn't feel safe. It also pulled itself up hills without too much slowing. It was also stock with a rebuilt f motor, vacuum advance distributor, a similar lift and 32x11.50 mud terrains. It did not have a hardtop or roof rack.
Is the extra weight and wind resistance of the top and rack and all the other little things like vacuum advance adding up here or should I try to give it a tune up? I hesitate to do this because like I said other then low on top end power it runs and functions great. In the past I have made things worse by trying to fix what isn't really broke. I'm not the best mechanic and its hard to find a good one that will spend the time on a carbed rig. They usually just say things like "Hey its old" or "It wasn't meant to go fast".
I doubt its anything serious or it would be much worse. It shouldn't need rebuilt at only 141k right? And I don't expect to run it at 70 to 75 down the freeway all day but it seems like it should do at least 60 comfortably.
Any advice or experience would be great.
Thanks
