wondering how to convert my hydraic flat tappet cam to an hydralic roller in my 76 351W block?

 

You convert the block, not the cam. Flat tappet cam goes with flat tappet lifters, roller cam goes with roller lifters. They sell retrofit kits, it's cam a lifter setups that are roller designed for non roller block. I've heard you can also do a bit of machining(drilling and tapping) and use a factory style roller setup, but I haven't done this so I'm not 100% sure if it would work on your block

 

you can do it on any flat tappet block. you need the cam lifter the dog bone that holds the lifters in place so they dont spin in their bores and then shorter push rods since the lifters are a lot taller

 

they sell retro fit cams and retro fit style lifters...however they can be quite expensive....If it were me I'd look for a early to mid 90's I believe 351 that came from the factory with a roller cam

 

ive got an 94 351W block will that work and i just use a roller cam and lifters

 

but i found alot of chucks in the oil the size of green peas, but ive got all new cranks an everything this be okay?

just take it apart and have it cleaned and magged at your local machine shop..that'll tell you if your working with a useable block
