You gotta wrestle these gorillas around with big forearms and an eggshell between the gas pedal and a sensitive right foot, becasue that is the real way they were steered around. Racing starts around 5:25.

Lots of power, but lots of grip and very light weight, only about 1500 lbs. I’d love to dive one.
My Dad took me to a few races in the late 60's and early 70's at Riverside International Ra ceway.

I read an article about a shop that was rebuilding a big block can am motor for a McLaren. Although the crankshaft was thirty pounds, it was still lighter per cubic inch of displacement than a modern-at-the-time F1 V8 engine. Which meant downshift blips were always in danger of zinging past redline.

Those motors were the ZL-1 427 big block Chevy’s. There wasn’t much difference between those race engines and the production units that went into the 2 ZL-1 Corvettes and 69 Camaro’s built in 69. They were monsters. The production engines were around the same weight as a cast iron small block.

CAN-AM and TRANS-AM were some of the best racing ever in my opinion. CAN-AM being the wild and crazy series and TRANS-AM being the production car series with the best drives making for some of the best racing. I always enjoy seeing the old TRANS-AM cars being tossed around tracks. The owners/drivers still put these cars through their paces.

wasn’t much difference? From my Pete Lyons book, he discusses t he Mclaren M8' s used bore and stroked 8+ liter motors . Their 495 ci motors had 600+ lb ft torque from 4k to 6k, 750hp peak, with good power all the way to 7800 rpm. They were using Reynolds Aluminum blocks.
And that was 1971 .
By 72 they built 565 ci motors/9.62 liters, But they couldnt turn that 800hp at the higher rpm. I dearly wish the turbo big block projects actulaly worked. They just couldnt get it reliable enough, but then their dynos couldnt measure 1000+ lb torque so they really were limited in testing. 4500 rpm and up was just guessing mostly.
So the only similarity to the street motors were the older Can-Am motors pre 70. Everything inisde was full custom.
Its a fantastic book. get it if you can.

That was great stuff, I have seen the vintage Can Am grid at Road America a few times. The cars, though certainly not tiny, are a lot smaller than they look (to me at least) in pictures. Big V8 and a small chassis.
Assume you saw the video of the big fly by on the main straight at Road America, man he is lucky it took off after the bridge.

I would love to drive one, but I think that is more power and performance than I could wrap my brain and aging reflexes around.

Love that stuff. Love it loveitloveit. I wanbt to build a 66 Mustang notchback with the flares and wheels and suspension look they used there. A real canyon carver, but weirdly an aluminum headed 200 inline 6 with itb injection on it....call me weird.

They were still Chevy based blocks. I know the Chaparral’s used the ZL-1 based block starting in 67 I think. Chevy took that engine block and had to add a fuel pump provision to use a standard mechanical pump and then they used a L88 intake and carb if I am remembering correctly.I dont think they did more r&d on intakes.

Yeah I’ve wanted to build a 67-69 Camaro that looks like a vintage trans am from a distance but have all modern drivetrain like a LS motor and 6 speed with really good suspension and brakes.
