Vortec engine questions...

[sled_dog]

anyone know how the reluctor ring and crank position sensor on a vortec motor mount? I haven't spent much time looking but it looks like the Crank position mounts to the Vortec's timing cover. So does the reluctor ring just slip onto the crank between the lower timing gear or something? I have a 383 I've been building over the past year or two and its about ready to go together and go in my S10. But I'm kind of thinking I should pull the stock Vortec 350 out of my 97 C2500 and drop in the 383 for a bit more power in my pickup.

what about emissons?

the reluctor ring does in fact slip on in front of the timing chain, and has a groove at the keyway. the crank sensor is held in by 1 6mm(?) bolt. i have pics if you need them.

as long as it will pass a sniffer test, nobody will know the difference between a 383 and a stock 350.

pictures would be nice if you could.

actually I don't know if its just around here but I don't think there is a sniffer test for OBDII vehicles here. Hook it up to the datalink and test to see it has passed all the onboard monitors and you are good to go. So with a PCM that eliminates those things, shouldn't be an issue to pass emissions. That or the fact that I have my inspection license and hopefully soon my emissions license...

ah ways around the system, you bastard!

here they are...

nothing really special to it. and the cover will interchange with earlier covers.

yeah I used a can of that... Guaranteed to Pass stuff.. worked like a charm
after I failed the first time.. ya gotta read the instructions though.. and also make your motor run lean and turn the timing down (or up I forget)... so it almost stumbles.... less power but burns more efficiently and emmissions are less...

eh screw it, I'm going to stick with the 350. I discovered today my truck does have to take a 2 speed idle sniffer test. I'm just going to do little stuff to the engine I have.
