hey guys, i have a chance to get a 351w from a truck for $150. the motor has a knock to it, but it turns over freely. my question is, is this motor a roller design? the truck is a f250 and i think its a 1993. the sticker on the drivers side door said the production date was 5/93.. i did some searching and it seems the magic year is 1994. so can someone help me out? thanks chad

 

yea 94 is the first year of the roller

 

Serial number will start with F4 for a 1994
and will have the holes in center valley to screw down lifter hold-down spider

you can still use that block with a roller cam you just have to use
the expensive ($400+) conversion lifters

 

do what r.barn says and check for the F4 # and please confirm if its true that 92-93 blocks were roller ready, let us know what the valley looks like.....either way 150 is a good deal

 

ok so i checked the number on the block and it starts with F4TE, so that means im good to go right?

 

yup... it means you have found the weakest model of 351w block.... good luck

 

Not really depends on how you get it prepped. I run that same blockand have over 300 passes on it and still runs strong its the motor in my sig.`An d its even .040 over.

 

still stronger than a 302

 

well weak or not, it doesnt really matter. im not looking for high horsepower numbers. i would like about 350hp with equal torque. i want a strong reliable motor for the street. i dont drag race my car. just want a quick street car. i would rebuild a 302 if i could find one, but a buddy found this one for me, so i thought i would go with it. thanks for the help guys
