I have a couple Saab B207R blocks. Their exactly the same as the LSJ block except for the oil drainback hole which is in the same place as on the LNF. I checked all the holes and bolt holes and their all the same. These engines were all turboed.

 

Good deal thanks for the info Jeff. Are the camshaft gears and cam position sensor the same as LSJ? thanks in advance

 

Your already in boost when you wot shift. No issues there.

 

No on The gears. They have no key.
Cam sensor yes.

 

thanks.

 

i wouldent say that

 

just a generalization...... of coarse there are always exceptions

 

Depends who tunes it....
Anyway, if you're worried about the boost hit of an sc you can always ramp it in with the disable vs tps/mph table

 

pressure is pressure however you make it. heat is heat etc.

whatever. my forlorn LNF bare block just sits here waiting for some lucky guy to buy it. Or not.

 

What's the tag on it

You have my email...

 

The cams are different and the heads in general are different . Exhaust port is smaller and they use different stud sizes. The cranks have a different sensor wheel style on all 3 engines so be carefull when trading cranks. I will post up a crank comparison soon. The cranks themselves are the same. Its the trigger wheel which varies.

 

I still have that LSJ shortblock for you John. Its yours.

 

The Saab head is almost like a hybrid of the l61&lsj.
The intake studs, the nub by the idler pulley, and ports are like l61. But it accepts lsj cams/ cam sensor and valve cover.

 

Btw, op, this (lsj in lnf) is what I'm doing for my build. But with mr belvedere sleeves.
