so let me get this right, if i send them my old camshaft, they will send me a performance re-grind for $29 USD +shipping?

My stock tercel SR5 with 147k, burning oil, and missing top gear will do 98mph on a flat straight away.

Well.....
Check out the copies of road tests from 1983 posted in the Gallery forum...
Neither R&T nor CandD testers, definitely not known then for kindness toward econoboxes, managed 85 and 86 MPH, respectively. CandD managed 88 in a test from a few years later. And the early tests were with the better "speed" ratios.

And I can vouch for an attempt looong ago, on a flat highway in IN, in the cold (windows closed), two people only, no cross/head winds, with my then-new '83 - to never achieving even 90 MPH (88, I think it was).

(Third post down).

As I mentioned at that time - the high speeds some now mention have nothing to do with the fact that our newest speedos are now 30 years old and kinda weary?

98MPH in 4th gear? wow!

my tercel has a hard time hitting 86mph with its 4AC in 4th gear.

I think theres some more gremlins to track down....

I can get up to 100 with no 3rd or 4th gear. You definitely aren't getting all yur hp's to the ground. Or it's not producing well.

My 84's top speed was about 85mph until the weber. I haven't really had it any faster yet but it has a fair amount of pedal left now at that speed. The taller tires and the 84's gear ratio helps keep the rpms down too.

With the right size tires on all 3 of my tercel speedo's have been right on the money as verified by everything but a speedo shop. I would take an old mechanical over many newer electronic systems. More reliable and often just as accurate from my observations.

On an old pickup that I put 32 inch tires on, I had to calibrate myself to the speedo error. Well, early 90's digital dashes that could be easily seen at night on the highway were anywhere from 1 to 9 mph different than mine. Final verdict by 2 gps's was 6mph. Can't always trust "new and improved"

Granted, with out doing any mods, my exhaust may be a little less restricted that it was new. . .

Just found the second page of this thread. Yea, I have reached 98 in fourth. my exhaust has found its own way around the catalytic converter and it takes about a mile to get up to that speed. I normally don't push my small motors like this but once, in my previous SR5 with all the gears working, I saw some body get away with running another car off the road and persued him to get his license. He didn't slow down for ten miles, til he thought he was in the clear. Over the coarse of that ten miles I hit 105 in a flat section. I may have had a tail wind.

[Lazymechanic]

Air temp has everything to do with top speed. Wind resistance is everything over 80mph and cold air is heavy air. I notice a big difference between 35 deg. and 65 deg. and when it gets down to the teens, forget about it. My speed assessments (and I'm not going to talk numbers here) are on 500cc single cylinder bikes, a 1000cc four cyl. bike, a 4.3L 4wd pickup and, of course, the tercel.

Well...if R & T and C and D and humble moi, all in then new cars with the speed gears, could not break 90...*

That is what it was a few years ago when I got mine. It is a nice street grind in MHO, peppy with a good idle and still has good economy. One of the best cams available for the money. You can still use the stock valve train too.

I think I totaly notice the difference of air temperatures, like one of the replies earlier, my car seems to be a bit peppier and seems to gain a bit more speed heading up the hill to my house on the by pass
