![]() 69-70 are great but slightly smaller deck height 71-74 are the ones i look for. try and get one with all the excessories and hardware with it. I always look for a vehicle that has been rear ended also look at trucks and station wagons before pulling from a car. if you want a roller like 86 up but i cant remember.
351 Block Castings C9OE-8 69-70 DZAE-BA 71-73 D4AE-DA D4AE-AA both 74-78 -deck height increased to 9.503 D9AE-ED 79-82 E3AE-BA 83-93 -change to external one piece rear main seal F4AE-?? 94-98 -change to block for roller lifters Deck height: 69-73 9.480" 74-up 9.503" 69-76 heads all use 1.85 and 1.54 valves with 60cc chambers. 69-78 heads all use rail rockers. 69-74 heads had L shaped water passages with 16 bolt intakes. 77-up heads used 302 size 1.78 and 1.45 valves with 69cc chambers. 79-up heads used pedestal mount rocker arms. 75-up heads had square shaped water passages same as 302 with 12 bolt intake.

![]() Thanks for that great info!!!!!
Looks like I want the 351W out of a ford lightning cause it is a roller motor. I plan on getting it rebuilt with 10.5 to 1 compression. Then get my Canfield heads port matched to a trick flow R intake manifold. Cant wait. Well hell i gotta blow this one up 1st.

![]() 69 351W blocks are supost to be the strongest from what I've heard.
The late model ones are really great though, with their roller cams and one piece rear-main seals -Josh, aka the tireburner
