First of all I personally want to thank Keith for stepping up!
I also want to let people know that Keith drove 12 hours to personally deliver the engine to Grimes Automotive. The fact he has put so much thought and time into this "challenge" demonstrates how serious he took this and believed in his products - to me at least. His knowledge of "engines in general" were confirmed based on his conversation with an inductee to the Drag Racing Hall of Fame "Hoyt Grimes" and and a couple of hours sharing information with Garry Grimes - the proprieter and engine expert himeself (yes, I had very, very little to add to the conversation but enjoyed being a fly-on-the-wall nonetheless - many of you would've too!).
The results were within 12 hp & 14 tq. of the results at his shop in Arkansas two weeks ago with peak power occuring exactly at 7,000 rpm's - as it had before.
For those of you who were curious about power a little lower in the "rev" range this engine had averages of 581 hp & 509 ft. lb. of torque between 3,900 through 7,000 rpm's. Torque at 3,900 (lowest rpm reading) is 477 ft. lbs. A few adjustments were made during the dyno runs which included increasing the main jets up one notch (now 13:1 a/f ratio) and reducing total timing down to 36 degrees. All other parameters remained the same. Having a variance of less than 2% in dyno results are more than acceptable. Thank you again Keith for making it happen and congratulations on pulling it off here in the Deep South. Best of luck and wishes!
For those with questions I'm sure Keith is more than willing to respond and share his thoughts.
PS. If anyone would be interested in seeing a pull or two by video let me know as I recorded several but need them converted to digital format from 8mm. If no one is interested I won't go to the trouble.
