Alot of the H, J, and I gas classes were filled with 6 banger cars --- but the record setting cars in those classes were ~~~~~~~ 4 cylinder VW powered cars - google Empi Inch Pincher, Deano Dynosuars, Tar Babe, and see some of the famous VW gassers from back than
I got the pic from here (modified production post) --------------------------------------------------------------------------------
There are pictures of the Seibert & Bugenski Vega that ran N/Gas with a "Jimmy" in the Bill "Redman" Floyd collection.
Late 60's Early 70's classes G/Gas 14.0 lbs. per cu. in. or more. Was flathead class H/Gas 6.00 to 8.99 lbs. per cu. in. I/Gas 9.00 to 11.99 lbs. per cu. in J/Gas 12.00 lbs. per cu. in. or more. K/Gas 10.00 lbs. per cu. in. or more. A bit of explanation is probably in order regarding the H/Gas through K/Gas classes. The H, I, and J classes were for “Non-supercharged flathead V-8s, in-line and opposed six-cylinder, straight-eights, and in-line and opposed four-cylinder engines with any type heads.” K/Gas was for “Non-supercharged flathead V-8s, in-line fours or sixes and straight-eight engines of American manufacture with stock production type heads installed in American production bodies.” Basically what was happening was that NHRA was making a place for the VWs and Fiats that were starting to appear in great numbers in the lower gas classes.
This 39 Chevy reminds of the 37 coupe that used to run every year at the "Antique Nationals" at OCIR and at "old" Irwindale in the 70's. It was primed "red oxide" - no running boards and ran a late 235 [?] with a 4 speed. It would scream - driver was so smooth it sounded like he was running an automatic. I wish I had a pic to post.
It was based off of a DUGGAN 292 block , but now it is BILLET Try GOOGLING [HARRISON RACING] for IGOR
The Hole Shot 6 ran from 66 till 72 with several different paint jobs and engines including a 292 Chevy, an OHC Pontiac 6, and a Pontiac tempest 4. It held a G or H gas record for several years until it was sold in 1972 without the motor. After the sale the car was never heard from again although their were rumors that a small block was installed and it was seen bracket racing occasionally around Michigan. The three partners on the car Tom Langdon, Marv Weigand, and Matt Martino then turned their attention to Streetrods and are still active members of the Michigan Hot Rod Association Millwinders. Many inliner also knew Tom from Langdons Stovebolt, and Inliners international. If anyone knows what happened to the Hole Shot I would be interested to know.
Actually it's a 230" Chevy I6 with an Aussie Duggan head, roller cammed etc, I almost read the printing off the pages when the magazine came out in June '79.
