timing todas

[ghetto3]

When i picked up the toda cams they didnt come with a timing card and im wondering how to set timing without it. Usually i'd find exact top dead centre by way of dial guage and extension sockets down hole no.1 and adjust cam gears to suit where id want cam events but without that all important x degrees ATDC@ .50" number im a little lost on how to time it up correctly.

The cams are 256/9mm lift todas if that helps.

set them you would like stock camshafts and timing belt.

camshaft dowels into I and E, locate I and E against their markings on the backing plate.

Thanks. It was the pin location that i didnt want to guess.

Dowels should be straight upwards from memory.

The cams will have some manner of retard because of the shave, and theres a good chance of kissing valves if i dont get the timing spot on. Getting the pins indexed will help get the timing close and i'll just have to read off a dial guage on a cam lobe to get the valve timing adjusted with the gears.
The timing belt will be a little loose becuase of the shave, getting it one tooth off would suck. Its academic really, setting them so they make power is one thing, knowing the degree of advance/retard would just help.

shouldn't kiss valves. those camshafts are still non interference with 9.5:1 pistons.

the exhaust cam for example is on .011mm bigger lift from stock lift.

i remember way back when i was doing research into it, you could go 9.5mm lift (with a base circle of 36mm) and still be non interference. going to 10.0mm meant you were talking thous of millis to stay non interference. too close.
