ha, my grandfather bought a new Buick back in the day with "radial" tires

looked flat and slapped the cracks in the pavement with a popping sound

of course, when drag racing my 70 Nova SS, I'd let a little air out of the back tires - 14 inch 60s

Summer tires today make a large difference in traction versus all seasons, which are still way better than any 1970 tire.  Put summer tires on that GTO and I bet the 0-60 time would come down 0.5 seconds.  Or more.  Sports sedans today can generate 1.0 g on the skidpad, way more than a sports car from 1970.

Tires are amazing really when you consider they appeared to be largely optimized by 1980 or so with little additional benefit to be had.

If you can manage it, running summer and winter tires in season provides a large benefit.

I have two sets of wheels for my pickup, therefore summer/winter

I can swap them as easily as a rotation in my driveway

My choice for an older muscle car would be a restomod with better brakes and suspension and an LS engine with the frame stiffened up as much as possible, and modern tires of course.  The solid rear axle would be left I think, maybe one could add modern positrac if needed.

Tires have improved a lot since 1970 in terms of traction, which aids acceleration off the line.
And cornering capability.

I think I remember the 1973 SD455 Pontiac Trans-Am cornering at 0.8 g, the highest any American production car had ever achieved.

Yeah, that's about right, my 1973 Nova was listed at 0.74g with bias belted tires and the F41 suspension.

My 73 cornered decently well on smooth pavement, for the time period.  It had the F41 suspension on it which meant higher rate springs and shocks and a rear stabilizer bar.  It also had leaf springs of course.

They didn't label it an SS in 73 for whatever reason, though it had a 350 in it.

I think that 5.7 L engine was rated at 185 hp, which is pretty pathetic really.

My Dad had a blue 1970 Lemans.  It was a nice car for the time I thought.

GM had a 350 cid engine for every mark except Caddy and they were all different engines.
