I am wanting to drill my block to allow a crank position sensor to run EFi. Has anyone got any specific measurements I can follow as I know this needs to be spot on position wise.

Cheers

I dont have any measurements, but i do have 2 other options, make a template up from an EFI block and use that to drill, or buy a 36-1 trigger wheel and mount it on the pulley end of the crankshaft, you will also then be able to adjust the timing (if need be) aswell as not having to change your flywheel!

ive got the dimensions around here somewhere
it will take a while to dig them out

Thanks for the replies. I already have the EFi flywheel on as I replaced it a while back so I might aswell keep it original. I think it might make life a bit easier in the long run.

Tim: Whats that then

All i can see is two tiny little nicks in the wheel? Thats not a 36-1 wheel is it?

Oh yeah i see them now youve said that. Where did you get the trigger plate and the sensor brackets etc from?

Looks like a tidy job
