That would be as measured at the rear wheels...the hp rating at the flywheel and/or as rated by Ford would be higher. :wink:

For the 3.3 or 200 cubic inch engine. Generally called T codes from 1963 to 1980, then B code from 1981 to 1982, X-code for 1983.

Net rear wheel hp never actually varied at all, despite fractory gross pre 1972 ratings going from 125, to 120 to 115hp, then post 1972 net ratings flying from 85 to 87, 88, 91 and 92.5 hp. Some were rated as SAE net, with or without the fan clutch in operation, and were fitted to cars with different emissions equipment depending on if it was auto, manual, California/High Altitidue or so called 49 states.


Stock manual transmission 200's in good shape from 1963 to 1983 always put out 65 rwhp. Emissions equipment made no difference at all, because Ford engineers always added better flowing cast in head intake manifolds, exhast headers, electronic ignition, better cam profiles and, eventually, better CFM carbs. The compression droped from 9.2:1 to 8.6:1 over those 20 years, which is a few rear horsepower lost. Some years, used awfull replacement part carbs, which would loose hp and economy, like the Holley 1940 Autolite replacement.

A manual trans is worth about 0.5 seconds over a quarter mile, or 4 or 5 rear wheel hp differnece on a stock engine.


The 250/4.1. Generally L code from 1968 to 1980, then Code C from 1980. The engine was a 155 hp gross engine, but later rated down to 145hp gross by 1971, then listed with net ratings of about 98 to 99 hp by the last time it was listed, as a C code.

It always gave in excess of about 74 hp.

Comparitively, the 250, despite its 25% increase in capacity over the 200, never made a 25% power increase because the extra dispalcement had to flow through the same restictive log had as the 200. It may have been listed as so by Ford, but it never gave the hp claimed.

When modified with a better head, the bigger engines (like the 1968-1995 164 hp gross Argentinian 221 SP and ME engines, or 2-bbl M code Aussie 250 170 gross hp version from 1971-1975), would become a standout perfromers, but until the Classic Inlines head, the 250 engine option has always just a stump pulling option, never a standout American performance engine in any of the bodies it was offered in. Its potential is just as great as the 200.
