Thanks Scott... Any updates on the Chevelle?

I have a MSD 6530 in the car which lets me adjust the timing to whatever I want to, the distributor is locked out, timing is set at 32 degrees and distributor locked down. I'll be able to pull timing out if necessary once back in the car.

For dyno purposes it was just flat base timing. Builder says these heads are just so efficient there is no need to chase any more power by adding timing too them, you just open yourself up to trouble if anything goes wrong (bad gas for example). He said there really isn't any reason to back any timing out at low RPMs either, maybe just a start retard that helps with starting but as you can hear in the video, it cranks over and starts real easy while hot with 32 degrees timing. Keep it simple stupid method in play here...

I wasn't too far off!!! And even closer if you look at the HP numbers at 6000 RPM's.



I like your numbers even better though!! That motor will be sweet. Glad this is working out so well for you Lance.

Nice Lance!!!!

You're going to need to bump your tire budget this season buddy. :)

Those are some nice numbers Lance. I have been strongly considering putting my dual plane intake on the ZZ383 I bought and seeing your dyno numbers just convinced me. Enjoy the new motor.

Close enough for nuclear war. :mock:

I had a feeling it leaned out more with the cleaner on to make the power. Lucky it didn't work out the opposite and not test it until you installed it in the car.

Thanks for all the posting of your journey. This is a real enjoyable reading!

Thanks... For anything other than just flat out drag racing or circle track racing, I couldn't see using the single plane intake. We did gasket match port my intake before installing and it took quite a bit of work...but the results speak for themselves.

Thanks Greg...I'm pretty stoked to get it back into the car, it should be a fun little beast.

After the Chiefs lost their football game tonight I played a couple of videos of me racing on the big screen for some friends that had never seen them before. All I could think about while watching other cars walking away from me on the straights at NCM was... "Not next year..." :D

I remember watching a Harley on a mobile dyno many years ago up at the local Harley plant during a show. They ran the bike with no air cleaner, then put a K&N setup on it and it made considerably more power with the filter on.

That was the first time I really started to understand airflow and power. Was kind of surprised to see this much change with my air cleaner on, but we backed it up with another pull and it was plain as day different.

You are right, I'm glad we tested it. Just imagine if we had leaned out the secondaries to max power with it off, then ran it with it on... :badidea:

Thanks Sieg!

I've got 3 sets of half used Falkens that are gonna have to get me through a track day weekend each this season. Then we'll see how many pennies I've saved back up. This little experiment took a bit more of a bite out of my budget than I was planning on.
