i heard rumors on all pa tracks going to 360 motors and full sized wings nest year. I know they ran full sized wings at lincoln for no reason a couple weeks ago. Any updates?

I asked this question a couple of months ago over on the Williams Grove board. See link below.

I personally like the idea. The 358's and 360's are already running together several times per year. It seems like allowing them to flex both ways would have a positive impact.

With that said, per the Williams Grove thread, it sounds like the 358 car counts improved this year. They may have tabled the idea...

Can anyone offer a brief explanation of the difference between a 358 and a 360? I assume it goes beyond just the 2 cubic inches of displacement. Thanks!

i did think that put the growing amount of cars during them 360 races of cars running a 360 motor

It's horse Hockey. The reason for the big wings on the 358s at Lincoln was to try to get everyone off the bottom.  At Lincoln the 358 races usually end up single file around the bottom. The track after the 410 feature is used up and really the only place the 358 could run was the bottom. They let them run the big wing one weel as a trial to see if it helped the car ability to move around the race track, and produce another racing groove for them. Guess what that night i saw the best 358 race of the year. 

yea slink i was there that nite too and id say it was a homerun for the 5x5 trial. look for more of that...

As far as I can tell the biggest difference in the 2 engines is on the top... the 360s have to use injector stacks with a max diameter of 2 & 3/16 while I have seen several 358 running bigger injectors... the 360 motors have to all use the spec Brodix 11x aluminum head with the ASCS logo in the ports while the 358s are on steel heads (usually Dart) and I think they are allowed to do port work on em.... I think the rest of the engine is pretty similar, and when they run head to head it's usually a toss up as to which one is going to be faster...

I have a feeling that the 358s are much more affordable to build for some reason, because when you look at classifieds a used 358 seems to be priced at around half what a used ASCS 360 motor is priced with a similar amount of races on the two.

Loose is when you hit the wall with the rear of the
car, tight is when you hit the wall with the front of
the car. Horsepower is how fast you hit the wall and
torque is how far you move the wall.

The 5 x 5 wings will only peter out the 360 motors for a rebuild sooner than needed compared to a 358. If the idea was to create better racing, I am not sure that is the answer. It just makes it easier for the drivers to run flat out with the bigger crutch on top. Unhook the cars & you will see if a driver can drive or if he just flat foots it all the time.

Not a $$$ saving idea what so ever. If they would have left the motor rules alone without the ability to redo the heads the car counts would still be around 35 per race & the cost factor would be more under control. That is what the class was created for.

The 360's have been running the 5x5 wings for years.

360's run aluminum heads. stack diameter is different too

Exactly! I'm in favor of letting the 360's run with the 358's, but with the 4X4 wing. Even the 410's are locked down too much with the big wing on the 1/2 mile tracks.
