I have a 93 Jag z with a '78 340 jag engine in it. When i open up the throttle, the speed goes up to about 85kph and the engine revs stay at 6000-6200 rpm and stays there......i know i can go faster, cuz with my 340 engin in its original frame, i could do around 70mph (my dad clocked me on the side of the highway) whats causing this? is there anything i could do to make it go faster? my friend suggested using Octane Booster and racing oil and maybe some pipes

It could be all in the gearing.

Zrt is right,check your gearing from the old sled to the new.
Also bear in mind that the 93 probably is a bit heavier than the 78 the motor came out of. ;)

Clutching also?

Just a thought?

:withstupid: It could be as simple as having the Clutches rebuilt, and replacing all the old Bushings and even the Springs. A mis aligned Clutch is a bad thing!

There aligned, we checked and rechecked. I want to try a stiffer clutch spring

Find the gearing and secondary clutching set up of a 91-96 Lynx/Puma 340

This would probably help since your are putting a 340 in the Jag you now have a Puma 340 ??? :D
