I'm nearing the end of my rebuild. I'll be glad when it's done. We really stretched ourselves out financially over the past 12 months. This is most of the reason my engine rebuild is taking so long. I get some work done, and then I need to scrape together some more $$ to do some more.
Just waiting to get some money up for the roller rockers, and stud kit. Then it should be smooth sailing from there. I suppose I could install the engine, and worry about the roller rockers, studs, and push rods later. (just realized that...:lol
In the mean time I just was poking around with Desktop Dyno 2000. It's probably not the most accurate. If I have the chance I figure I'm going to see about getting the 'burb dyno'ed once the engine is back in.
But the estimates on DD2000 say that I should expect about 278hp/418ft-lbs. vs. the 220hp/385ft-lbs from the factory.
It doesn't seem like much, but the last time I sent the burb in for an inspection it failed, and they gave me a paper with the run down on the findings of the inspection. It also stated that the engine was putting out 90hp.
I know the engine seemed kind sluggish, but I didn't figure it would be that low, but I guess it wouldn't surprise me. I never asked how they got that figure.
DD2000 doesn't take the roller rockers or roller lifters into consideration, so even though I don't have the roller lifters I'm sure I'll have a few extra horses more than the estimated figures with the roller rockers.
It does have an option for headers, and from the stock headers to large tube I should see figures in the range of 337hp/469ft-lbs.
That's something I can live with:great:
