Production Class

[Clay Pitkin]

Another rule/class question:

For the production class, can a car have an engine change that is the exact same size as originally came from the factory? Or does it have to be the exact same engine that was in the car from the factory?

Does that make sense?
TIA

As long as it is the same type (same manufacturer, model, etc) of engine you should be fine.  Serial numbers do not need to match if that is what you are asking.

Swapping a 2000cc Toyota into a 2000cc Honda, would be a No Go.

Swapping a 350 SBC for another 350 SBC of the same generation, should be OK.

Actually putting a 350 SBC in a car that came with a 265 or 283 is OK in Production. They don't really mean Production. It's pretty well explaned in the rule book I think

I'm not used to seeing that said on this forum.

Dan says it all the time. And there is a lot about the rule book that is clear, so nobody talks about it. And some, like the XF and XO requirements that seem clear to me but people still want to run 392s in the class. Maybe I'm just getting older and tired of bitching.

Look at the definition of engine swap in the rule book. (I don't have mine with me or I'd quote the page number) If you do "an engine change" in an otherwise Production or Production Supercharged car and that "engine change" meets the definition of an engine swap, then it ain't a production car any more . . .  Probably would be a Gas Coupe (like your Suzuki) or maybe an Altered depending on any other changes to the car because of that "Engine Change". 

So . . .No . . . you cannot change engines in production if that engine change is considered an 'engine swap' even if the replacement engine is the same size (i.e replace a 302 Chevy V8 in a Camaro with a Ford 302 V8).

Basics, if the engine came in that type of car from the factory that year, NOT Necessarily in THAT car it's good.

So if you have a 6 banger Camaro but Chevy put a 427 Big Block in it that year, you can put a 427 Big Block in your 6 banger and go for it. good luck holding the drive train together

But yeah, default to the rule book

In the rule book section 4.N it states that an engine family is defined amongst other things as be made out of the same "basic" material.  This implies that you can't use aluminum heads unless they were available from the OEM.

However later on in the same section it indicates that a crate engine is not considered an engine swap.  This could be contradictory in that you could have a crate engine with an aluminum head when one was not available on the original engine.

To me it seams that an aluminum head should be allowed as long as it meets all of the other criteria stated in the rule.

At least with respect to GT, essentially a production class, the use of aftermarket heads is allowed, provided they are of the same design as the stock heads, use the same bolt pattern, and the same port configuration.

The snow mobile engine in your car kicks it from Production.

[RichFox]

In Production Pickup you can not modify an OEM Stude head to have straight out from the exhaust valve ports while making it a four port head. Maybe if we made the center port still Siamese? What about using a splitter on the center port? Is that illegal? It more or less makes it 4 exhaust ports. I still say, Dan was right. And the Salt Cat guys got screwed.

Rich, I find that, now that I'm older, I bitch more, I'm just not correct as much.

Back in the day, SCCA Pro Rally rules clearly said any engine from the same manufacturer. So, daydreaming, we considered a Messerschmitt car, which was basically a closed motorcycle with 2 seats in line, and the 1,455 hp V12 engine from a Messerschmitt airplane.
