3.42 + big cam like ms3 on ls1 347cid will not make your setup more streetable and the drivability will be off the line ! .. unless you have great tuner that will spend time tuning the car on the street ! I think Faisal Dashti is the way to go there if you still wanna go with the big cam route

You will need smaller cam ; lower 23x duration or higher 22x for better drivability to take the advantage for small-mid cams powerband N/A

Big cams make more power up top and sure as many said you will need lower gear ratio (4.10 or 3.73) to take the advantage of the big cam powerband. Small cams on the other side make more hp/tq on lower and mid rpms which your (3.42) will like more and in your case with the beauty of TFS-215 and such good compression, I'm confident that you will make nice top end with much smaller-streetable cam

Vengeance / Parick G / Predator Z / Geoff @ EPS can set you up nicely in this with custom camshaft

Nice comparison you need to look at

 

thanks for the info
but i really like the ms3
many of my friends have it
and i guess ill install the 3.73 gears like many suggested so
it will be better with my setup
but i hope i will be able to use the nitrous
with great turnouts

 

Swapping the cam you have for an ms3 is pretty pointless. Unless your doing it yourself for free I would not waste the money on it. I would spend my time finding someone who knows how to tune it right.

 

my friend will swap it for me
he is a car machanic and he also has a camaro
and he moded his all by himself
he has a mini garage in his backyard
and in there youll find the 1100 whp beast camaro ss
that he owns
which no one in the streets of kuwait wants to race with
it has a stroker engine + supercharger + nitrous
he made 740 whp without nitrous
and he uses a duel nitrous shots of 200 hp
his car is just a monsters
and he know what he is doing...
so swaping a cam for him is like a walk in the park
also my friend told me to take it to some tuner he knows which will hopefully tune it right but now im waiting to by the 3.73 gears and wait for the weather to get fixed so i can tune it
its really dusty and windy now and it gets around 50 •c
in the day time
extra hot weather now a days in kuwait (((

 

Arabian Gulf weather = buy a car cover and keep it until November when it is get cold .. and we are waiting new eXtermination VIDEOS

Guys from US .. can you just close your eyes and imagine yourself driving your H/C f-body in 122 F .. that's what we got here ..
