big block 454
Iv got a big block 454 4 bolt that i built and it constantly over heats if i drive it over 45 mph. if it is pulling, and tacking over 2,500 rpm it over heats. iv got an electric meizure water pump on it with duel electric fans, and a 4 core aluminum griffin radiator. Iv tried the timing, the gas air adjustments on the carb thinking possibly to lean.. But nothing works. and the entire engine is brand new. edelbrock heads, intake, complete rotating assembly etc! Iv checked the thermostat, and gone over everything a hundred times, just cant figure it out.
Can anyone help me with this please?? Any advise i might have over looked.
