Looking at the HP increases.. What caused the increase from 132 to 148?
wasa it more than HD8 carbs and a different Cam profile?
I have a BT7 engine with BJ8 cam profile , HD 8s and 40+ overbore. The
internals were balanced as well. So am I pushing  150 bhp? or has something
else been tweaked on the BJ8 engines?

That's pretty much it. Of course they heads and other bits were reworked a bit
but it was principally down to carburation, cam profile, "breathing", higher
compression and that's most of it.

As for whether you are reaching 150bhp, that rather depends on what else you
have done and on your engine's general state of health of the engine. The only
way to know for sure is to stick it on a dynamometer.

Healeys probably pushed 150bhp in rally trim from the late '50s.

Hope that helps,

Peter
