302 TO 351W NEED LIST OF SWAPPABLE PARTS

[Blackbirdws6zzz]

I am building up a 351W right now. It's a 74 truck block and everything is brand new on the inside including the crank, the pistons are forged trw peices. they are slightly dished with valve reliefs. the rods are forged as well. Has a crower flat tappet cam.

I have an intake and carb for it.

Now i have a 89' LX 5.0 I just purchased. Is half way switched over to carb. Car is a Auto. Can someone give me a list of parts that are swappable from a 302 to the 351W.

Can the timing chain cover?

Thanks in advance!

If you do a search for this 351w swap you will find all you need to know.

I have done my research. VRDSTANG or whatever has helped alot. Didn't see anything about the timing chain cover?

 

[86bluecobra]

I believe the timing chain cover is reusable.

Yes the timing cover will work. I'm using timing cover from an efi 302 on my 74 351w block.

I'm also using the roller lifters, spider tray and the dog bones from the same 302.

While this setup does work, it is not recommended.
In order to use the stock 302 rollers in a non-roller 351w block, a small base circle cam must be used. (so I am told).

The small base cams are harder on the valvetrain components and there is a limited selection of lobes available.

I have run the reduced base cam for about 10k miles, but most will say that it is not the best way to set things up.




I will have to double check my writeup on the timing cover.

A friend of mine who owns an engine machine shop told me about the reduced base cam. I'm planning on running a cam with no more than .530 lift and driving it no more than a few hundred miles at a time max.

I'm no expert on it, I just don't want to spend $400-$500 on link bar lifters.
