302 Clevor engine in 2wd Ranger

[1990 sc]

Back in the 60's Ford found a way to dramatically improve the performance potential of its 302/351 motors - enter the Cleveland engine. The new Clevelands had radically redesigned heads, included cavernous port volumes (especially in 4-V form), massive valve sizes, and altered valve angles. Never mind that the Cleveland heads bore a striking resemblance to those porcupine heads on the big-block Chevy, their flow potential (especially in modified form) far surpassed anything available for the Windsor. The fact that they performed so well in NASCAR, NHRA, and even Trans-Am racing helped sell the Cleveland as a high performance street motor. Though the flow was up considerably compared to a Windsor casting, the performance-orientated 4-V Cleveland heads proved a might too large for most street applications.

The 408 hybrid stroker was installed on the engine dyno and allowed to break in for 25 minutes before we changed the oil over to Lucas synthetic. It was then run in anger and tuned to perfection using the MSD billet distributor and jetting/air bleeds in the Mighty Demon carb. After only a handful of tuning runs, the Clevor thumped out an impression 660 hp at 6600 rpm and 595 lb-ft of torque at 5200 rpm on (91 octane) pump gas. The torque curve produced by the hybrid stroker was impressive, exceeding 550 lb-ft from 3.7 rpm to 6.3 rpm. Even way down at 2500 rpm, the stroker thumped out over 500 lb-ft of torque. Obviously, the CHI heads and intake combination were doing their job, allowing the 408 Clevor to not only produce exceptional peak power but also (and more importantly) one heck of a potent torque curve. so dont tell me it cant be done no 4.6 will kick my ..Hinny lol its funny when i will be the last one laffin. an the chevy boys are crying at the track

just be known, u will need to box the frame all the way back, cross brace the hell out of it. the ranger frame simply isnt made to handle the sort of stress such a motor will put on it, i have seen time and time again rangers with powerfull small/midblocks and big blocks
