I found the casting numbers on the block. They are E0AE D30. So that means it's a 1980 block right? I also noticed the firing order is 1-3-7-2-6-5-4-8 and runs smooth. So does this mean it already has a cam since the H. O. didn't come out until 82 I think.

On a side note, where can I find the numbers on the block to verify my motor? Is it possible to see them with the motor still in the vehicle?

Actually any EFI grind makes a carb more responsive. The stock Ford F4TE cam in the roller 351 works great with a carb. Do yourself a favor and build a 351, don't waste your time on a 302.

A crate motor with a warranty is never a bad choice , or if you want to build your own get a 351 with a roller cam . These motors came in 94-96 trucks , if you search you can find one cheap.

As money allows then buy the parts you need for thr rebuild , once you have the parts have the block machined then assemble or have it done .

Depending on the quality of parts chosen a crate motor can be less expensive.

I am currently looking at getting a 351w roller block. Any ideas on which way to build the motor? Build it one piece at a time or just get a complete top end kit? Which would be the better outcome in terms of performance? I still want to shoot for the 350-400 hp range with around 400 torque. Should be pretty easy on a roller 351. Still looking for a slight lope at idle but good driving manners, but if I have to sacrifice manners, I am ok with that. Also would like to build it for a supercharger in case I add one later down the road. Rather build it that way right now instead of having to do it later.

I have found the 351w. It has 385hp and 410tq. Any recommendations on a tranny to back it up since it will destroy my aod. I am slowly converting this truck to 4wd so a tranny that will work for both would be nice.
