I have a frozen motor for my 1957 TR3A TS33154 (Project car).
I have a spare motor from my TR4A Parts car (Motor is also is sad shape)
I know that the TR3A motor was 1991cc and the TR4 was 2138cc - correct ? (In
most cases)
The diff in size was the sleeves.. no ?
My question is: How compatible are the two motors if I find something in my
'3 motor is no good ?
TR4 motor number is TS13959E
TR3 motor number is TS81530F
Thanks all !
Pat
PS: You have all been a great bunch and a wealth of information and help..
thanks.
