Finally got around to dyno'ing this baaaaaaaaaad boat anchor. The best I can tell, it's the highest known hp/ci pump gas 400 based engine around. Within 17hp of the highest known stroker that has 30 more cubes and a better hp/ci than the engine masters build in 2015.
This is LEBs attempt at building a world class pump gas street build Ford 351m/400 to compete against some of the best names in the business. Our most important concerns were reliability, run well on pump gas 93 octane and enough manners and vacuum for it to be fun to drive. Granted, we left some RPM and horsepower on the table in order to achieve these goals.
Lets start with a breakdown of the build:
Factory Ford 400 block - extensive internal oil mods and gyptal epoxy coating
Factory Ford 400 crank - polished and deburred
Factory Ford 400 rods - LEB prepped and machined
Keith Black/TMeyer .030 over pistons with 13.4cc dish. 10.99 static compression
Total Seal file fit ring package
Balanced using a Pro Products 351w balancer and 351w SCAT SFI flexplate
Hydraulic roller cam - LEB custom spec. Reground off a Lunati retro roller blank
Howards retro style hydraulic lifters
Cloyes double roller timing set
Melling standard volume oil pump - maintained 73-77psi on the dyno with 30wt oil
Moroso rear sump 7 qt oil pump
Trick Flow 225cc 351c heads - CNC chambers
2.08/1.60 stainless valves
PAC racing hydraulic roller spring package
3/8" guideplates.
ARP head studs
Trend chromemoly custom length pushrods. 3/8 x .080 wall
Trick Flow 1.73 roller rockers
Edelbrock RPM Air Gap for a 351c. Belly pan machined off, extensive port work, Price adapters and Jet Hot coating
1" Jomar power cone
Quick Fuel 750cfm mechanical secondary - custom built
MSD distributor
Everyone wants numbers, so here goes
588hp @ 5500rpm 573tq @ 5000rpm
