shouldnt be screaming with those gears in it

Does not make much sense, unless it has 10 in rims.
I purchased a 63 compact a few years ago, which had two diff ratio replacements before I brought it, chasing a lower crusing RPM.
Flicking the 4-6-8 switch on the aftermarket rev counter fto the 8 position soon fixed the problem.

I've been thinking my speedo is out and going faster than I thought if you get eat I mean

so if its screaming perhaps you need to check if it is actually in top gear cos it sounds like it has not changed out of 2nd how stop, select L, drive off, select 2,etc, make sure you can feel it change up each time, at 100 km there would be stuff all engine braking when you button off ( with that diff ratio there;d be virtually none until you were doing 120 plus and harsh decelleration at that

Ok I'll try that but took it out tonight and went threw all gears so think its changeing fine

thats a poss, diff head changed but speedo drive not, get a mate to mark out 2km, drive it at 60km, should be 2 mins for 2km, then drive it back at 100, should be 1min 12 secs for the 2km at 100km/hr post back the times, that will tell you if the speedo is completely out of wach or within quooee

I rekon it my be the speedo drive giving false reading coz wasn't changed when conversation done does that make sence

a 2.9 is long legs, unless the trans is on it's way out you should be cruising at less than 2200 rpm at 100km hr
skin1235,
Jan 24, 3:09am
lets call it a conversion, although we could have a conversation about it lol thats not a dig at you, I have words that refuse to come out right too

Lol sorry doin this off an iPod small screen and old eyes lol
skin1235,
Jan 24, 3:15am
and yeah, you haven't told us what conversion was done, so assume it was the engine. and the engine doesn't alter gearing to make it re higher as you say in your first post you'd have to change rims and or diffhead, or possible gear clusters
a note : that 2.9 would go REAL well if it was behind a manual box, especially with 15 inch rims - clip on a set of235 /75/15 tyres and stall it every time you select top at under 85km hr

Yes just engine so I'm buggerd if I know now I'll fOllow a mate tomorrow at a 100ks and see if we are close or chase a copper and get him to clock me lolol

okay,
is it screaming ( you can actually hear it or feel it ) or is the rev counter saying its reving too high
skin1235,
Jan 24, 3:25am
take your foot off the pedal at 100km, does it slow down real quick! cos if it is reving it will slow down like you've just pulled a handbrake
a 302 cleve will near lock the rears under engine braking

Have no rev counter just feels it wants another gear
skin1235,
Jan 24, 3:29am
not silly though, if it has wof and rego approach one, he'll quite possible be happy to clock you on the 'hawk'

top gear was vacumm operated I think, if you have a hose wrong you wont find top
try it at 80-85 pull it back a gear - you should feel it change down, then pull it back another when you get to 60 - if you can't check them going up check them coming down

I reckon your wheels are to small, or the vacuum from manifold to the back of the trans has come out/not working - so not getting top gear, or the Torque converter is wrong or faulty - does the engine get very hot!
