the connector wont even plug into the 60e trans you will operate in 3rd gear only. you have to change to a 80e and also a different drive shaft due to the larger output shaft in the 80e ...or.... you can have a built 60e to run behind it but you would have to find out about other computer options. the tranny will bolt up fine................................Red03silss the block is the same as an ls1 no bolt up issues.
