1970 LT1 ZR1 Convertible

[TimG]

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.

And then you still need to find the rotors.

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!!!

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

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.

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?
