Firing order swap

What would be the advantage or reason to swap the firing order on #8 and #2 cylinders?
I was looking at some roller cams on Cranes' website and they have these listed as SF01 firing order.
I used the forum search but found nothing about this.
Thanks.

Easier on the crank and bearings.

the ford 8 - 2 swap is the same as the chevy 4 - 7 swap, the firing orders are actually the same. the numbering scheme is just different

in you research it may be easier to find reference to the chevy 4 -7

It may be worth a few horsepower with certain intake manifolds however, cost probably makes doing this prohibitive to most.
This is also the same firing order as the flathead Ford used years ago.

If you're going to order a cam that isn't off the self, I can hook you up and it won't cost more than any other custom grind. Let me know.

the Question is why change something that has worked for say what the last 40 or so years? If it was so hard on Bearings wouldn't KY's engine show it? He is definitely hard on one and his bearings looked New....JMHO I think it is a waste of your Money I have not seen any Proof it is better or worse, no Dyno Proof, no real time run proof. just some one thought it sounded good so whalla it is better.....

Oh I have some majic snake oil to sell only 8 bits a bottle, it cures all, aches and pains,it cleans stains on cloths, and you can drink it also

Yeah I know Coug. I have not tested it myself. Kaase has, and he says its better, so that is why I had my new cam ground that way. The only guy more knowledgable with BBF is probably Randy. Its a Monkey listen - Monkey do for me! Charlie had made a very good comment about the firing order in another post.

Now, if its not an all out build, then by all means, get a cam off the shelf and save a couple of hundred for the pro comp upgrade.

If I get Kaase to say to fart in the intake it will be better does that make it better?


I would like to see proof, (on 2 cam same size exactly alike just dif firing order) on the very same engine done back to back on the same Dyno everything the exact same but the cam just having the different firing order swap..... That would be proof in black and white....These Pros that build these Big Pro engines they will jerk your wanger so you won't keep up with what they are building.....their secrets are just that their secrets....

This is from Kaase's 2005 engine master "Pontiac" article.

The engine has a changed firing order. It's a 1-8-7-3, or a 4-7 swap. Because of this firing order it seems like it caused some problems in the manifold, and it made the number eight cylinder lean all the time, but with a different order it would have been somewhere else. We went to that firing order on our bigger [race] engines, and our crank life improved, so I think it is better on a bigger engine, but on a single four-barrel, I'm not sure."

New here. I was informed about this site at US60 Speedway 2013 event a week ago.

Everyone knows how Well the 302 was Transformed in the 80s with the 351 Windsor Firing Order. Apparently this FO is also far Less Stressful on the Crank and Bearings and the Mains. I performed this swap myself in 83 knowing how different/Better a 351 ran compared to a 302.

The 302 and 385s share the Same FO. I questioned Kaase Engines about the Use of the Windsor FO, if they ever tried it and I'd be Very Interested in Dyno Results of such a swap. I also asked why they do Not build Ford's Pro Stock Engines. I was emailed by Cliff Moore at Kaase and he informed me that they have, in fact, tested this FO. He said "it Made MORE Power, But our engines make so much power anyway, we don't feel the need". (???)

I feel that this cam/fo swap would make a Huge Difference like the Unleashing of the 5.0 and it would also Sound Different !!

I am planning a couple of different mule engine BBFs for dyno testing of my heads and manifolds. This could be an interesting test. Baseline the engine, then just change a "swap" cam for an identical grind with conventional firing order. My 618 has the swap order on the 60 MM Comp stick. As I recall, our Comp rep recommended the feature for my application.
It would be much more cost effective to do the test with a standard journal cam...and not the 60mm.
More things to ponder and test....$$.
Thanks

It's only money Keith, you can't take it with you! Seriously though, I'd be interested in the results of an honest test like you're talking about. Keep us posted.

Hey Keith,you are OUR test mule. We always enjoy your tests. Keep up the good work brother. Me and Hobbs will save a spot for you at BG. If we're not there when you pull in,We've went for more BEER.
