70 LT 1 Q's

[Dennis D.]

I believe 1970 LT1's didn't have power steering. Correct? Also believe the 1100884 alt was used. Anyone know of the 1100542 application? Don't think LT1. Little long distance research.

Can anyone make out the last letter in the date code?

Early 1970 LT-1 engiens were equipped with "6 quart" oil pans. None of those could have had power steering. Later 1970 went to the "5 quart" oil pan and I believe that this was done expressly for the purpose of making power steering available.

GM #1100884 was the alternator used for 1970 Corvettes with LT-1, among other applications.

GM #1100542 is a 63 amp alternator used for some 1973 model Chevrolets, but not Corvette.

When in the year would you expect to see a 5 qt LT1 pan?

Anyone with a 5 qt pan in a 70 LT1? Date?

Dennis,
My 1970 #14803 is an LT-1 with a 5 quart pan.

Dave,

Puts you about a month later than my 6/16?

I believe that the earlier "6 quart" pan engines had the "CTU" engine suffix code and later "5 quart" pan engines were "CTK".

Dennis,

Looks like the letter B for close ratio M21.

Re: 70 LT 1 Q's

Dennis/Joe,
My #14803 is a "CTK" motor. If my memory serves me right the change over occurred in the #5000 - #6000 range. I believe the 70/72 TIM & JG adresses this.

Re: 70 LT 1 Q's

My #1799 is a 6 quart oil pan with CTU designation.

Re: 70 LT 1 answers are in the TIM&JG as

well as a story some years back (pre-1999) in The Restorer. Unfortunately, I have access to neither here in San Antonio.
