Anybody running a spacer under the TBI?

[Chili 87 K5]

Please: If you know what the ballpark timing should be for a new 1" TBI spacer, give me a hint... I just need to know where to start looking.

Is it closer to 12 degrees BTDC? 20 degrees? Is there a good place to start trying?

Thanks!

I'd be totally amazed if adding maybe 4 cubic inches to the volume of the intake manifold would require a timing change. The difference in total intake volume is probably less than 1%.

I have an Airaid on mine and I didn't have to change the timing at all. I did have to adjust the linkage on the tranny to fix the shift points.

GOT ROCKS?

Can you notice any difference with these things?

I have one on mine, and it seems to help out a little.

I'm running a injector spacer and the edolbrock intake. Plus a Turbo city cone on the air cleaner. I cant help on the timing though as I'm running a 400 block that 30 over with the stock 93 head and stuff

I understand the jeep thing I drive a BLAZER!!
