WOW, WOOKIE. Can you give a run down on engine parts/combination. awesome, my son and I have started on a 512-B engine but haven't picked out a cam or carb as of yet. your engine is beautiful!
I like to call them "Mean Mothers" because of the ramp rate but I believe they actually stand for Muscle Motors. Comp 6584/6585 is the #.
Nothing real trick in the build. Block has the lifter bushings and all the typical machine work. Custom Diamond dome Pistons with gapless top ring pack, 13.7-1 CR, 2.25 intake valves and heads flow 359 @ .600, Harland 1.6's giving it .635 lift, PSI valve springs, Titanium retainers, distributor is locked, Dougs 452 headers. Pretty much sums it up.
I've have always liked a higher C/Ratio in these motors, especially at higher elevations where I am. Then when you combine high C/R with a high flow head, you can get some real big horsepower/torque numbers, such as what you have here. I'm curious as to what thickness/type head gasket you are using? What is the quench/squish clearance on this engine? Thanks, good job. Nice build.

My 451 has a C/R of 13 to 1, .037 quench distance. 915 heads. Runs mid 12s consistently. Producing 460 horsepower.

I lose 77 H/P at 5600 feet, so actual horsepower at altitude is 383, according to the Wallace calculators.
Are the HS rockers staying adjusted. When will you have some 1/4 mile times and what's that other engine in the background with the up swept tubes on it?
I believe that engine is a boat motor that makes much more power than mine.
Before this engine had 11.3-1 CR and made about 650 HP. At that time it ran 11.60's around 119 in my 4500 pound sled. I lightened the car up at least 400 so I should now be 4000-4100 at the line. ET calculator says with the extra HP I now make it will be 10.60's at my weight. I have an 8" converter now, low gears and a brake in the tranny, so my 60's should jump from the 1.62-1.65 it used to be.
At least 3 months till my first trip to the track now. I'm excited to say the least.
