With the hypermax car going as fast as it just did, the bar has been raised. I am confident I can run 6.70 and 6.80's, but that car is going to go 60's and 50's at will. Congratulations to them, its great when you see a program come together,
I’m moving forward on two different engine programs to answer this new challenge. I worked with CN Blocks and they now have a Dmax aluminum block that is everyway a BBC pro mod block with the exception that a Dmax head will bolt to it . This is not a repop of a stock block in aluminum but a real race block. It uses a BBC DRCE II oil pan, cam drive, and slightly modified crank. With the weight reduction in block and crank the savings is a little over 200 lbs. me in up to a 4.32 bore , and will handle a 4.5 inch stroke.
You can call CN block tomorrow and order this block for about $7800 and have it ready with 9/16 head and 5/8 main studs included in 4 to 6 weeks.
To compete with the current bench mark . I’m skipping that step all together and going on to my Big Block Dmax engine program.
I have 3 different head programs in work now , one is a 4 valve head that is a BBC , and is converting fairly well . the other is a billet Dmax cheater head that was done for a 2.6 puller , trying to hide is under stock parts, and its being grown up to the 4.840 bore centers.
This is what the BBC CN block with a production head block looks like , this is a Chevy block, but its exactly the same . you can call CN blocks and order this block tomorrow
Here is the 4 valve billet head, this head flows twice what a Dmax head dose with flow numbers close to 600 cfm
Here is the cheater head that will grow up to fit a BBC block . I met with this guy at the Dallas event while helping on a NHRA 500 inch effort, we are working together to get a new head out soon .
In the end this is the best alternative to make a mid-6 second diesel that can get under the NHRA SFI mandated weight.
I know I can compeat, with a raceable car
