Question: Can a late model 5.0 cam be used in a 69 302? I realize that after a certain year (85-86?) Ford switched to a roller cam, obviously this would not work without a major retrofit. What I really want is the 351 firing order, is it possible to attain the later firing order with only changing the cam? or do I have to order other parts? The only reason I want the 351 or 5.0 firing order is to facilitate a possible future EFI conversion... thanks.

Yes you can use a 5.0 roller cam, but you will need a late model dist gear & retro-fit lifters ( FMS-M-6500-S58). The firing order changes and you just move the wires to the correct position. ------------------

Get a 351 Windsor cam. It'll fit the 302 and it has the H.O. 5.0 firing order 1-3-7-2-6-5-4-8.------------------

Kevin is right, you can install any 351W cam and get the firing order, but for future EFI compatibility you want to stick with something with around 112 lobe speration and not too radical.------------------

I just checked that out on Ford's page; EARLY BLOCK HYDRAULIC ROLLER LIFTER SET Is there anyway I can do this without spending the $469 to convert the block to accept the roller cam? If not then I will gladly stick with my early firing order... thanks

hey thanks guys, everything I needed to know! p.s. once I select a cam I'll post back before I order it to make sure you guys think it is 'ok' for my setup. So there are no real drawbacks to using a 351w cam in a 302? No other parts need to be added/modified/or swapped? thanks

302 and 351 camshafts are identical aside from firing order. The only information I've found leads me to believe the stock cams have the same duration and lift as well.

Thinking ahead, if you are going to do a EFI swap and use the EFI distributor, you will have to change the gear on the bottom of the distributor to match the cam. Regular hydraulic cams can be used with a standard distributor iron gear. Roller cams are harder and will eat up the gear, so people switch to a bronze gear for a standard distributor. Likewise, if you use an EFI distributor (to match your computer) you would want to match the gear to the type of cam you are running. Scott

I'm running a steel gear with no problems, the bronze gears wear out too fast if you drive any on the street, IMO. I would prefer to run one of the new composite gears but I haven't gotten around to getting one installed.

If you use EFI with a mass air flow meter you can run a lot more cam than a speed density setup will tolerate. I put 1989 Mustang GT SEFI with mass air on my 1967 F-100 and the F-303 cam sounds pretty nice for an every day driver!------------------

if you are talking a 5.0 hyd roller cam then the only way is to buy expensive link bar conversion lifters. If it is to use an HO efi system then I think you can just swap the order of the injector wiring to match a non HO firing order......I think.The easiest way to go roller cam in a 302 is trade your 69 for an 85 up 302, theres plenty in the junkyards I see them all the time in my local pick your part shortblocks for 75.00 complete engines for 150.00 might as well just get a 351w after a while you will want more anyways, now I'm doing a 408 cuz the 351w isn't enough....... my 67 vert http://htwheelz.smugmug.com

In order to use the 5.0 roller in your block without buying all that upgraded stuff, you can very carefully drill and tap the block for the lifter retainer

If you use the 5.0 roller retainer and lifters, then you have to get a small base circle cam. Stock 5.0 cam and lifters are too tall for the early lifter bores.------------------
