Hi all, just joined to get this simple question answered...please answer if you can, or point me in the right direction...THANK YOU VERY MUCH IN ADVANCE!

*I am rebuilding an engine for a friends 84 240 DL sedan with the N/A 2.3L motor...and can get him a free head from a 1987 (same make/model) TURBO 2.3L...

And I'm wondering if anyone can tell me the factory compression ratios for these two motors:

- 1984 240 DL sedan with the N/A (naturally aspirated) 2.3L
- 1987 240 DL sedan with the TURBO 2.3L

I plan on re-using the cam from the N/A motor on the turbo head...and am wondering if the ratios are close enough to get away with this swicth.

Thanks again for reading!
