Awesome cars!!!! Ed Foss had #2950 at 2013 NCRS Nationals in Hampton, Virginia!!! Wow!!!

I should have said, 1970 ZR1 Corvette's are awesome. Have no affiliation with this car or if it's legit.

Brought darn good money. Very nice car.
Other than the M22, the power brakes, what else is different between an LT-1 and the LT-1, ZR1?

Stiffer springs and shocks?

White LT1's are few and far between, not a common colour for LT1's for some reason. Convert LT1's are rare, but a white convert ZR1 would be one of one or two(??)

Zr1 option got all the L88 parts.. smaller 10" flywheel, hd shocks, bigger sway bars, j56 brakes and TI ignition (not 100% on the last two)

HTH

I am sure someone will correct me if I am wrong, but I believe the only brake upgrade would be power. I think the calipers are the same.
Both would have received TI.
The bigger sway bars and hd shocks make sense.

[69M22Z]

ZR1's,ZR2's had to have power brake and J56 big brake.

Thanks for the correction.

Guessing the big brake parts are impossible to find.

And then you still need to find the rotors.

ZR1 included M22, F41 (although I don't see it on the paperwork), and J56 (automatically includes PB). Also, no fan shroud and 10.5 inch clutch. The pilot 1970 going through Mecum has F41 on the paperwork and my understanding is that F41 was part of the ZR1 package. Every document I have for 70 - 72 ZR1's has F41 included.

The calipers were the stock ones with the top pin hole ground off. They had a reinforcement bracket for the caliper too.
The calipers are the same as stock, the pistons have a shorter piston with an insulator screwed to the piston.
Stock calipers were easily converted, finding the bracket was the hard part ( some one was repoping them)

1970 was only year with a fan shroud. M22 and F41 was only on a ZR1 in 1970. 25 M22's and 25 sets of F41 suspension parts in 1970. ZR1 was an LT1 with a bunch of L88 parts. Power brake, big brake. Awesome cars!!!

[69M22Z]

Couldn't get a radio. Pretty sure no power steering either but not 100 % on that.

[TimG]

No Power Steering on a ZR1. I have many documents for '71 and '72 ZR1's and all have F41 and M22. In '71 and '72 heavy duty suspension was coded as F41, but called Sport Suspension.

[Lynn]

My understanding is no power steering on LT-1 in 1970 until late in the model year. PS required a different oil pan.

That's correct. ZR1 had a 6 quart pan.

This appeared to be a pretty nice car and restoration. I love the options and color combination. I did not see any documentation, is it a known car?
