So I just swapped in a 248 exhaust cam into my intake side of my 95 KA. Here are some pics of how it looks now. How can I check if I did it right or not?
I rotated cam gear by 3 teeth BTW

thats not tdc on the crank

Heres mine without the 3* at TDC

OP, your cams look off... set it to TDC, and set them correctly

DennisC · 06-17-2012, 02:42 PM

I will try to set it at TDC then take a pic of the cam positions.
OK heres how it looks like now. To me it looks like I did it correctly. I just didn't have the pics in the first post set at TDC because I didn't spin the engine back to TDC yet.
Edit:
I just got it running and took it for a drive and it drives awesome. The only problem is that when I came back home, it stalled out when I stopped. It wouldn't start back up. But I got it started after letting it sit for half a hour. But when I revved it a little, it stalled out again and won't start back up again. what could had went wrong? Reset the ecu already btw and I noticed it was idling kinda low at around 500-600 so I just adjusted the iacv a little and I'll try starting again in a bit.

Great job. Was gonna do this swap too. Did you have to change any shims under the buckets, or was everything close enough? Valve clearance?

DennisC · 06-18-2012, 06:02 PM

It fits perfectly.

Looks wrong. I did 4 teeth. Cams facing out along the same plain roughly. Does it backfire when you crank on it? I went back to stock cams pretty quickly. Didn't like the loss on mid range. Ran hot and too much overlap without redrilling the fear. did you time the dizzy correctly?Put the stock cam back and see if it runs.

I got it to run decently after I opened up the iacv screw a little so it idles normal. I am going to adjust the dizzy tomorrow to advance the timing a tiny bit.
