Hey all I'm almost done my LT1 Conversion. I was wondering what kind of numbers you are putting down on the dyno, and track (1/4).

 

Anyone rofl?

 

95 m6
long tubes
40s dumped
306 bone stock heads
1.6 rockers
mail order tune

made 335hp/360tq
ran a couple of 12.8s @ 114 on street tires with crappy 2.1+ 60 foots. Then spun #7 & #8 rod bearings in the water box.

 

Jeezzzz.

 

Do a search. 330 to 350rwhp seems to be about average for the CC306.

 

cc306
1.6 nsa rr
gmpp guideplates
csi electric waterpump
stock heads/bottom end/intake/timing chain
stock injectors
mail order tune

automatic no hp/tq numbers but it went 11.9x at 113 (1.66 60' spinnin)

6 speed it made 353/358 and went 12.7 @ 112 (2.0 60')
both were in about 3450 pound cars...

 

mine is going on the dyno next friday but it has ran 12.4 @114 in a full weight hardtop without the jack, spair and front swaybar.
