did a convertion for a friend. silvertop in ae111. he run a bearing in the BT.
convertion was heart of motor ST
BT extrators, throttle bodies, intake, computer, everything elce realy. only changed the "long block" to ST.
I got to drive it once, but man, did it fly! before the convertion the clutch was on its way out (yet still able to hold) with the change it would slip HARD in second gear, forget nailing it in top. (yes, adjustment of clutch was fine). it certainly wanted me to put BT throttle bodies on my ST ae101. no way did this lose bottom end, or mid range.
yet, with a computer like the BT has, it simply took advantage of the package.
compression is less so can hold a higher ignition advace before knock pulls timing.
bigger flowing throttle bodies and exhause system leave the head/cams to be the limiting airflow issue. also state of engine (unknown kays) so no history and wasnt torn down or freshen up.
more proved the BT computer, or more the package deal is a better unit than ST.
Put it simply, it was a mutant.
Pitty the owner was too and crashed the thing
