crate engines crate engine development process all great crate engines start as an idea the engineer begins with a horsepower target and the engine family for hitting that target then the engineer documents the components that will likely achieve targeted horsepower and meet durability requirements this procedure is based on years of experience in the high-performance engine building business many formulas also support this process next the engineer has one or more development engines built and sent to crate engine part number displacement ci horsepower hp torque lb-ft compression ratio heads camshaft crank piston intake distributor valve cover oil pan water pump crate engine part number displacement ci horsepower hp torque lb-ft compression ratio heads camshaft crank piston intake distributor valve cover oil pan water pump crate engine part number displacement ci horsepower hp torque lb-ft compression ratio heads camshaft crank piston intake distributor valve cover oil pan water pump m-6007-xefm 302 340 310 9.0:1 x303 gt-40 e303 hyd roller cam 3.00 stroke cast 4.000 forged no intake no distributor m-6000-k302r production serpentine belt m-6007-d347sr 347 415 400 10.0:1 z304da f303 hyd roller cam 3.400 forged 4.030 forged victor jr billet distributor m-6582-r302 7qt rear sump v belt m-6007-d392ft 392 430 450 9.7:1 x303 gt-40 crane hyd roller cam 3.85 stroke cast 4.030 forged victor jr billet distributor m-6582-e302p 7qt front sump both the engine dynamometer lab for break-in and testing during dyno-testing fuel distribution best cam timing and best ignition timing for maximizing horsepower and torque are assessed if target performance numbers are not met or can be improved changes are made accordingly oftentimes different carburetors camshafts intake manifolds and cylinder heads are evaluated after target numbers are reached the engine is run for durability durability testing is based on the m-6007-z50z 302 390 360 10.0:1 z304da high flow z303 hyd roller cam 3.00 stroke cast 4.000 forged no intake no distributor m-6582-r302 production v belt m-6007-d351ft 351 385 377 9.0:1 x305 gt-40 z303 hyd roller cam 3.50 stroke cast 4.000 forged victor jr billet distributor m-6582-e302p 7qt front sump both m-6007-d392rt 392 430 450 9.7:1 x303 gt-40 crane hyd roller cam 3.85 stroke cast 4.030 forged victor jr billet distributor m-6582-e302p 7qt rear sump both m-6007-x342 342 n/a n/a 10.0:1 x303 gt-40 x303 hyd roller cam 3.40 stroke cast 4.000 hypereutectic victor jr billet distributor m-6582-e302p production v belt m-6007-d351rt 351 385 377 9.0:1 x305 gt-40 z303 hyd roller cam 3.50 stroke cast 4.000 forged victor jr billet distributor m-6582-e302p 7qt rear sump both m-6007-z351sr 351 400 375 9.0:1 z304da hyd roller cam 3.50 forged 4.000 forged victor jr no distributor m-6582-r302 10qt rear sump v belt market application of the engine various durability tests may be run sometimes as severe as 50 hours at wide open throttle full power others may be cycling tests where the engine accelerates from peak torque to peak power then decelerates back to peak torque then repeats the cycle for many hours the tests selected vary depending on the market application upon successful completion of durability testing the engine package is released for production m-6007-347nst 347 n/a n/a 10.0:1 z304da f303 hyd roller cam 3.40 stroke forged 4.030 forged victor jr billet distributor m-6582-r302 7qt rear sump v belt m-6007-s58 351 250 350 8.5:1 production cast iron standard hyd cam 3.50 stroke cast 4.000 hypereutectic frpp dual plane ford duraspark m-6582-e302p full sump production v belt m-6007-c392rt 392 475 495 10.0:1 z304da high flow hyd roller cam 3.85 forged 4.030 forged victor jr billet distributor m-6582-e302p 7qt rear sump both m-6007-z347 347 450 400 9.7:1 z304da high flow crane hyd roller cam 3.40 stroke forged 4.030 forged victor jr billet distributor m-6582-boss 7qt rear sump v belt m-6007-j58 351 240 340 8.5:1 production cast iron standard hyd cam 3.50 stroke cast 4.000 hypereutectic 2v aluminum ford duraspark production full sump production v belt m-6007-c392ft 392 475 495 10.0:1 z304da high flow hyd roller cam 3.85 forged 4.030 forged victor jr billet distributor m-6582-e302p 7qt front sump both 82 techline 800 ford788 not legal for sale or use on pollution-controlled motor vehicles direct replacement part see pages 2-8 for important safety emissions and warranty information.
