Connecting rods

[roadrash375]

Near ready to send the 235 to the machine shop, am planning on putting 270 rods in (Full floaters versus semi's ) Planning on running in E/PP so this should be OK . My question is, are these rods allowed in the XO/XXO classes should I choose to run in these classes ?  Thanks in advance Mark

You can run titanium or wooden rods in those classes -- no restrictions.

In the recent past I attempted to run a 256 GMC in E/FR class. No go. Vintage engines must run in vintage classes. So you will be in XO or XXO Gas coup I guess. Bad deal.

Even if you turbo it Rich? The question has been bothering me.

Trent, it's my understanding that a turbo will take you out of Vintage class, and into a modern engine class- no turbo's in Vintage.

You can run tubos and EFI on vintage engines, just not in vintage bodies. Tony

Your right Tony.

Cool, thanks. Clarifies some stuff in my head

Deleted . . . wrong information

I ran turbos on my 270 in my Vega. As do the Salt Cat guys now on their Buick. But with the Turbos on the 270 in my 32 I was given the feeling that I wouldn't be running at all. Or just for time. As always, after listening to me you might want to check with somebody who knows what they are talking about.

A Turbocharged 235 in a tank would run in XO/BGas or Fuel Lakester. With a Wayne head it would be XXO/BFL

 Thanks for the responses.....little clarification on my part. The truck I'm planning on running in E/PP is a 59 Chev and the 235 is the original block for it . Nice to know XO and XXO are options for the future! Thanks again

You are planning on a 235 Chevy 6 against a standard 800 HP 258" SBC?

Good luck,

Dan’s point is a good one but may have added some confusion. You have to be careful and be sure the “X” motor is listed in the class. For example, in PP or BMP an “X” rated motor is listed (pun intended). Therefore, it will only have to run against another X motor and not against an “E” motor. If the class does not have X listed then you are running your X motor against anything of similar cubic inch sizes.

For further confusion, the Classic Category (1928-1981) has no X motor. So if you wanted to run a turbo flathead (XF) in your 71 Nova you have to enter the car as a blown gas coupe BGC in the Modified Category (post 1982). You would be severely handicapped though, because modern sedans have much cleaner aero.

XO and XXO asre your only options. E is not an option.
