Re: Gear stick keeps coming off
Interesting tidbit if info, I had auto ratios, cant remember off the top of me head what they are, but in top at approx. 5000 rpm I wound off the clock. Over 210 klm/h. 8o| 1st gear could net me 75 - 80 klm/h at red line. ;sigh; I miss my ol' Corty now :cry: More than likely a 2.78:1 in your cortin...

Excellent, thank you. This leads to a few more questions: Which of the later heads offers the best flow? For a NA motor making around 100kW ATW, is there any reason to use an Astron1 block? Can the later hydraulic rockers be converted to solid? the M6-7 have the highest flow however the M8-9 are a ...

Re: Wat sort of cam are you running ?
a speco MS344 ( Billit cam of cause )
in 45 / 75 ex 85 / 45 with 267 deg @ 0.050" lift --
its quite a nice wide range cam on the 2.6 that runs ok from about 2000 rpm
and starts to move well once past 3000 and was making Max power at 6100 of cause it runs through to and past 7000 fairly quickly

Re: Astron 1 head swap
The only negative is you will also need to get an adjustable cam gear and pack out the hydraulic tensioner to compensate for the extra chain length. as Scott has said shaving the head needs an adjustable cam gear - you retard the cam timing about 1 deg or 2 crank degs for each mm you remove from th...

Re: Help. How to back off the timing chain on a 4g52
if you undo the big bolt at the front of the dizzy drive gear ( 22 AF socket from memory ) the gear pulls off and should sit on a sheet metal sadle
then you can drop the cam out
just do the reverse on assemble there is enough give in the chain tentioner to lift the gear back onto the cam

ive heard that the 2.4 destroker makes more power over 7000 Why ? my understanding on offsetting the bores is you get more leverage on the crank at the moment of ignition (ie: instead of the piston and rod being dead vertical above the crank relying on the inertia of the flywheel to pull it all aro...
