It's just my opinion, but those 882 heads aren't helping you much. As for your quoted 9.1 compression, Did you actually cc and measure everything to verify that? Many years ago I had a set of 882's with flat top pistons and did all the cc'ing and actually came up with 7.9:1 static compression ratio. Like the other guys are telling you, the 882's serve a good purpose as a boat anchor.

First off I want to thank you all for the replys What I discovered (and now I remember) last summer in an attempt to save fuel, I changed the vac. sec. to a heavier spring. I forgot all about it til today. I put the light spring back in this morning. I,ll go for a spin later today and see what happens. Wish I remembered that yesterday. My trip to the dyno was a waste. Its tuff getten old.

I'd say the results are dead on for the combo of parts.. A little tuning may net you another 20hp but... For that combo, I'd say its about right.
Smogger heads, tiny cam, no compression, spinning a heavy T400 and probably full accessories/clutch fan etc etc.. Pretty much all it's gonna do until you upgrade it.. You have enough steam to run 14.90s as it sits.

Thanks guys

Here's an engine dyno result for an engine much like yours, except with better heads:

I know, you can't really compare the numbers from an engine dyno and a chassis dyno, but you can compare the shape of the curve. I think a better set of heads will let your engine continue producing power into the upper rpms. Go aluminum.
