Andy, we discussed 572-13 heads and just simply decided against it. Woulda loved to see what woulda came from that but knew there was plenty of other people out there, to include DVW, going 8s in the 1/4 and 5.60s-5.70s in the 1/8 on a 440-1 head. Figure that’s fast enough for my buddy even if we came close, so he was good with going 440-1 and that’s how it went. If I ever had the money to do another engine, it would absolutely be a 572-13 headed combo.
Doug, 14.68:1. We are absolutely hoping if we get the car down under 3400 lbs that we can run 5.70 or even faster. But just trying to be realistic and conservative, if it runs 5.80s he will be happy.
68roadrunner, .776/.754 lift at the valve.
n20mastr, it’s absolutely a bracket engine. The oil pressure drop was because the vacuum started to pull above 11”. Will have to see what it does in the car goin down the track. If it starts pullin oil pressure then we will likely lower it a tad. But that’s at the track adjustment. As far as shifting it, will have to mess with shift points at the track to see what’s the most consistent. As of now the plan is 7,000 shift points. I know my bracket engine and Tim’s bracket engine we both shift 7,000 1-2 and 7200-7300 2-3, and they live. But again that’s at the track we will figure it out. I think your performance goals are realistic!

I seriously doubt it will ever generate a timeslip to back up what they claim. Goodwin builds some cool stuff, but where are they finding an extra 200 hp that NOONE else can w/ a 440-1 head? And it's a nitrous motor at that.

My dyno numbers are the car weight and ET slip computed for my ultra sleek aero dynamic car. Doug

The combo Todd Marsh put together for me with -1 heads exceeded our expectations 540 low deck made 881hp @7000 which was about 60 to 80 more than what I expected, so get the right combo is the key, just need to get it all finished and hit the track. Doug
Sorry honey I spent the rent
