I have had my 1977 F-150,(460) completly redone everything inside is new except the crank, just needed to be polished,the cam(comp cam) is the biggest you can use with a stock torque convertor,stock heads,airgap intake,Holly street avenger 670 cfm,long headers/dual exhaust,stock distributor,roller rockers,C6 tranny,3:50 rear gears with 235x75x15 tires.I set the timming @ 12 btc.My problem is that I have a 74 f-100 stock 460 except for the 4Bbl and headers,350 gears,same tire size, when I drop the tranny in low hit the gas the tires smoke all through low gear.When I drop the built(mild) 460 into low hit the gas it won`t even break the tires loose.If I break torque the 77 it still does not have the power to break the tires loose.It is not exactly a pig but the stock 460 will show me its tail lights.I put more than a few dollars into this 77F-150 and the stock (except for the headers)74 460 beats me home every time....anyone with any ideas.Thanks in advance!
