Wasn't the 250 the heavy duty version with 7 main bearings? They say that one is good to 7000.------------------ '70 Mustang Mach 1 M code 351C 4V/FMX/3.25 open '72 Mustang Sprint Coupe 351C 4V/FMX/4.30 Trac Lok '94 F-150 XL 5.8L/E4OD/3.55 Limited Slip '97 Probe GTS 2.5L DOHC Keep your driveway ALL Ford!!!

Yeah, the 250 has more cubes and is more durable. Its a better starting point, although I've heard that the 200 heads flow better.

The post-'66 200 also has seven mains. The biggest problem with putting a 250 in a Falcon/Comet/Mustang is the height of the engine. The block is almost 2" taller than the 200 and makes airfilter hood clearance an issue. The 200 and 250 often came with the same head castings so there's really not a difference in capability. The big rule of thumb is later-is-better. Post-'69 heads have bigger ports and logs. Post-'75 heads have bigger intake valves (1.75" vs 1.68"). Post-78 castings have induction hardened exhaust seats for unleaded fuel. Check the Ford Six Forums for a 200-250 swap FAQ. ------------------ Jack Collins '66 coupe 250 Crossflow / T-5 Click here to visit the Mustang Six website!and The Ford Six Performance Forums
