Whats the main difference in the 84-85 prelude(A20ES) and a BT? I have a blown BT in my dd and I found a 84-85 lude motor on ebay. Can I just switch manifolds? Are the bottom ends the same? All i really need is a short block.

This may be a stupid question, but what the hell is a bt? As far as motors go, Im pretty sure that gen lude had the same motor. the only diff was transmission gear ratio

The block and head are compatible. You'll probably have to use all your original mounts and brackets and such though.
