IHRA ss/am Attn: Jim Reynolds

[Ron E]

Jim doesn’t spend much time on the boards, so if you don’t mind I’d like to address your post. My association is only that our shop does Jim’s airflow work.
You may already be aware, but if not, Jim bumped the mark in totally legal SS/PB-1 trim. Stock stroke, single carb, and 3500 lbs. Also, when he bumped the record he was shifting only 300 RPM above the peak power RPM. The plan was a slight bump
His big block was designed for around 900 more peak RPM than it is currently. It was dialed back with a different cam. This was to keep the valve spring costs below that of a typical heroin habit. It was agreed that if the need ever arises, the stick and springs can be changed. The heads are already sized and flowed through the lift range for the extra RPM. We’ve had some 3-teen CI motors with intake lobes as big as Jim’s big block. So, it’s an understatement to say there is more when needed. Add the RPM and another carb and there’s still an easy 100+HP on the table.
Jim does have a much better (on paper) ss/am combination (different car/engine) that can run at minimum weight. But, the ’57 is relatively new and has been the focus for the past year or so. Besides, it’s just plain cool to see such a tank like that ’57 run as hard as it does.
Since I answered 1st, can I claim the steak and beer offer?
