I am running 14:1 on alcohol. Hoping to run into the 8s at 3100lbs on 10.5 with stock suspension.

Start at 34 degrees and see how it goes. I run 34 with a 440-1 head, which has basically the same chamber shape, and I have 15/1 compression and 528 cubes. A 572-13 head is basically a 440-1 casting changed from 15 degree valve angles to 13 degrees, and the exhaust is moved to make rom for a bigger intake valve. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

My combination is a 4.5" bore 540, it runs 5.50's - low sixtys in a 2975 lb car with a bracket race tuneup, terminator, 31 degrees of timing, loose converter and is killer consistent.

Car was running with the 572 Indy crate engine a few years ago, but I think they had a smaller cam back then maybe the CM2 or R2 as it was making around 830hp (think thats what was stated when the engine was bought). Ran 9.2 at 149mph back then and neded some work on the front of the track. I have just reused the heads and have a cam similar to the CM3. Hopefully get some track time next weekend. 8465436-10958047_10152683348168157_3752323918240502426_n.jpg (224 downloads)

I need to get the chassis certified for this season so I can run it in the nines. Once that is done I will set it up more aggressively. The track I race at has a physical elevation of 1600' and is not know for having great DA. Last edited by Saskabusa; 03/28/15 05:30 AM. 1974 Roadrunner 1967 Charger

The track I race at has a physical elevation of 1600' and is not know for having great DA. OK...so it's a fairly mild setup w/ not so good air. Still seems down on power, but maybe the cam change will help since the original cam was somewhat of an unknown. I'd bet it would run better w/ the 440-3 intake instead of the big 3X. Has a lot of potential, just needs some tuning.

Went from hi 10.20's to 10.00s never ran a 9. Maybe had something to do with the pro systems carb too.

I am running 14:1 on alcohol. Hoping to run into the 8s at 3100lbs on 10.5 with stock suspension. Many many varibles....but - I tried alcohol for a little while with the 572/13 combo and the timing didn't seem to care between 29 and 34....more or less and you seen a change. I went back to gas and it is very critical - 31� no more no less. Thats with 116 octane and a agressive cam at 15.2 static. Personally I dont think those heads are big enough for that cubic inch and alky. I found that even with gas that you need to focus on building torque rather than trying to spin it up. Been messing with the same combo since 1999.....I think I have peaked it out
