Swapping a 351m for a 460
Performance Automotive Warehouse CA pawengineparts.com? sell a frame adapter from Transdapt #9433 about75$. The egine isolators can be bought from your local auto parts... the application is for a 73 to 79 f series 2wd with the 460 option (i just paid 56$ for the pair). The shells that mount to the block are from the same application but i just recently tried my local dealer and he said they are obsolete.?! you may have to scrounge the junkyard scene or fab or get lucky in the aftermarket (let me know, i'm going to fab mine but would rather not) finish off the swap with hooker #6841 engine swap headers... the cheapest? price for those is at summitracing.com $370. some thicker flywheels may require you to notch the bell housing for clearance and watch the throw out forks, too. the alt and power steering has to be mounted high a fab project. My first swap was from a tired 400 to an approx 500 hp 460 and got 8mpg from the 5600 lb truck. but i trade the 850 dbl pumper for a 750 vac and now get 9mpg ... but it needs to burn premiun 10.5:1 ratio. good luck dnadzam@atsengineers.com
