This build has been a long time coming. LOTS of challenges initially and my schedule hasn't allowed much of anything the past 2 years.
First off, many thanks to the following:
- My wife and daughter for puting up with my crazy hours and always being gone....only to head to the garage or track to play when there is a little free time.
- Max and Ben Long at Long Racing Engines in Irving, TX. Thanks for the top notch machine work and letting me completely disrupt your busy shop to dyno my misfit naturally aspirated combination for a few days
- Curtis Boggs at RFD for working with me on his 15 deg. "Monster" heads. Very impressive heads and his latest stuff is even better. Nice job and thank you Curtis!
- John Wilson for selling me his hand me down Crower shaft rockers and help on the dyno today. Thanks bud!
- Mike Lewis for working with me on the custom Diamond pistons, Total Seal Rings, and EZX lifters
- Chad Speier for the work on the 2959 intake plenum and spacer.
- Charlie Gilbertson for working with me on the custom oil pan and screen.
- Loren at Crower for working with me on the custom shaft rocker stands.
- Rick at BLP for the custom carb parts and advice on the carb build.
- Paul Swartz for the custom billet top and plenum spacer assortment for the sheetmetal intake to be tested tomorrow.
Stuff like this doesn't just "happen." Lots of talented and good people behind any good build.
Engine:
- Dart 9.325” deck Iron Eagle Block
- Callies Magnum 4.125” stroke crank
- Lunati 6.125” Pro Billet rods (ARP 2000 bolts)
- Diamond Racing - Flat top inboard pin boss custom pistons (15.1:1 true compression)
- Total Seal, .043 top, .043 Napier 2nd, 3mm low tension oil
- Race Flow Development – custom CNC 15 deg. SBC Heads. 2.18 Ti intake valves/1.625 Ferrea SS exhaust valves.
- Speier Racing Heads ported Edelbrock 2959 (4150) intake
- Crower 1.7/1.7 SS shaft rockers
- Isky Red Zone .842" EZX lifters
- Trend 7/16” double taper pushrods with 210 deg. ball
- Custom solid roller cam - 274/296 @ .050, .864/.810 lift on a BBC cam core
- PAC 1228 springs with Manton Ti retainers – 330 psi seat/1000 psi open
- Jesel Belt Drive
- GZ Motorsports VP103 vacuum pump (12 in-Hg......worth ~12 HP)
- Star Machine vacuum pump mandrel
- MSD Pro-billet distributor and Crank trigger.
- Joe Gibbs breakin oil
- 2" to 2-1/8" dragster/chassis car style custom headers with Pipemax designed collectors.
Still some testing scheduled for tomorrow(sheetmetal intake), but here is some quick general info (by memory/notes) so far after 15 pulls. Lots of timing changes, jet changes, air bleed changes etc. to achieve the seudo optimized numbers below.
I will post sheets and more details later next week.
C14 fuel:
timing 31.5 degrees
Pro Systems 1100XC - 850 HP @ 7200 RPM (Reher-Morrison shear plate/spacer was worth ~10+ HP)
Holley 1000 HP(850) with annular boosters - 828 HP @ 7500 RPM (Was down by about the same amount the entire pull.) This carb has a dual bolt pattern Quick Fuel baseplate and 4150 to 4500 Super Sucker style adapter/spacer mounted on top of the Moroso 2" 4150 to 4500 spacer........so it is about as apples to apples as I could get. Note that the stock Holley jetting was dead nuts on this carb.
Home built/modified carb with BLP parts - Holley 1250 HP - 860 HP@ 7200 RPM / 671 lb-ft @ 6100 RPM (no spacer)
I was REALLY wishing I had an R-M 2.125" bore shear/plate spacer for the big carb!!!!!!!
Q16:
31.5 degrees timing
1250 HP carb from above - 878 HP @ 7300 RPM, 673 lb-ft @ 6300 RPM. Bleed changes were worth ~8 HP
Sheetmetal intake (several tops) and some Royal Purple XPR 5W20 are on the slate for tomorrow.
Hoping for 900+ HP tomorrow from my little DIY project.
