so thats where all those trailers were going last weekend, didnt know there was a division race going on, i need to try to get out to one of those events
ummm-well-in the current era-BUT Ken Duttweiler built Buick Grand Nationals went into the 7s in NHRA legal SS trim with Ron Fruchey and John galina (sp?) years ago....Also, Frucheys was 215 inches at the time
Just curious, what's the ss rule on cylinder heads? Any head produced by the same manufacturer even if not OEM? Does it have to fit a production cylinder block? Why not the new Nascar engine? Thanks for any info.
retrofits are allowed , but must be approved
I know the standard super stocker run bowtie blocks etc
