Did you use the wrong locator pin hole on the cam pulley? aka are the lobes on no.1 facing upward and outward when TDC?

Did you forget to plug the CAS in?

[dehney]

Cams are in right when I removed the stock ones I put the new ones In right away in the same angle. No cas it's dizzy. I'm thinking because the cams are 8.35 lift that could make a differents so since the lift is bigger do I still use the stock markings ?

[Skylar]

The CAS is the thing inside the dizzy that senses where the crank is in it's rotation.

Are the lobes on no.1 facing upward and outward when TDC?

Spark/Fuel?

[dehney]

yeah thats all plugged in
there is a pic for the cams at tdc



i think there the right way but i could be wrong

[timbo]

pull you dizzy out and make sure it is aligned for tdc as this could be an ignition timing issue. it may have jumped a tooth in either direction when you put the new cams in. so leave the motor at tdc, pull out dizzy and line up the two markings and very carefully, so as not to bump the gear, put it back in. also wouldn't you be better running the 264 on the intake?

I see a dizzy drive gear on both cams....wouldn't that mean they are both exhaust cams?

I don't know how aftermarket cams are set up for 16vs but I'd be wondering if the timing marks are for set up for exhaust cam use only.

[dehney]

there hks cams i think they always came with the dizzy gear on them i dont know if the pin on the stock cams are different from in too ex.

im going too try what you said timbo tomorrow with luck it is just a timing problem

[Skylar]

I'm going to put cams in the SR tomorrow/Sunday/Monday so I'll take a picture when I do that. Pretty sure they should be more upright than that.

do a compression test. you should know if it has no compression. it should turn over VERY quickly..

if it has compression (which means your cams are in "properly"), spark or fuel is the problem.

i would be dialing in those cams properly though. will need some adj cam gears for that.
