how do these rules compare to john sears rules?

i ask cause Nate's Ultimate outlaw race runs johns rules and will be at piedmont. Hoping some guys can do both races
B, the guys that run 275RS run 5.50 - 6.0 for the most part, they run with Mike's series inconjuction with X275. Plenty of cars to go around for each class in that area.

It would be cool to try and run these at all the ultimate outlaw races ...including milan...but why the 525 bbc limit ...540/555/565 is so common at the tracks seems your excluding tons of cars ...hell very few people build under a 540 unless is to class like NMCA ...just asking the question...or is there a weight penality for being over ??? I could run both as my combo is a 555 with a plate...

Is there any kind of cubic inch limits on 4 cylinder entries?

Are the trickflow LS heads not legal since they are not 15 degree?

all ls heads must be 15* . no ci limit on 4cyl entry.

harleyman , the bb ci limit is not just chevy , its all bb IE: FORD ,CHEVY, MOPAR. that ci limit will stand at this time. i'd like to keep the rules the same for the remainder of the year. unless something drastic happens. thanks.
