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.

I think a lot of racers and want to be racers and want to be HP engine builders don't realize that the race car has to have all GOOD parts from the front bumper to the rear bumper to outrun all other cars and racers in the same class, HUH Al ,Thumper and many other good racers on here work scope
I used to help a couple race a NHRA Hemi stocker back in the early 1970s, we had bought an Art Carr "8 inch" drag race converter from him, that thing was absolute JUNK down whiney I took it back to him many times to fix it before giving up on it and finally bough good a Turbo Action "J" converter up I learn years later that Art had bought out a decent commercial and race converter company (Hawaii racing) in SO CA that had moved their machines and good inventory back to Hawaii where the owner was from shruggy
We found out the hard way about buying and using known good race parts shruggy
That being said both engine and chassis dyno should be used as a tuning tool to help you learn how to work on and go faster with your toys: scope wrench up twocents

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

Thank you guys. I definitely will keep everyone in the loop when the car hits the track and what it runs, which we all know is the true test. Fingers crossed.

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
