The Syclone/Typhoon 4.3s are liquid-intercooled aren't they? There's a guy around the corner from me with a mint lightly-modded Syclone, he has a huge heat exchanger is in the bumper's lower opening and I couldn't help but wonder.

 

Sounds like an awesome project, are you keeping the AWD? I never cared to pay attention to what transmission they used, but I'm assuming the 700R4 is a RWD trans?

yes they have a liquid to air intercooler mounted @ the throttle body from the factory. i will be using a front mount air to air in my car. i only bought the motor/trans, the owner of the Syclone has a 6 liter with a 4l80e in the works and is looking to get 900hp...

 

the truck comes with the 700r4 with transfer case for the AWD. all i need to make it RWD is a tail shaft..

well i set the motor in just to see what i will need to do for the oil pan and motor mounts. to my surprise it almost fit perfectly, the pan does hit the center link but not by much.

look how low the pan sits :eek1bluegreen: i'm going to swap out the pan with a 2wd pan, i was told it's about 3" shorter.

my car is still at the stock hight.

Sorry to throw this thread off-center, but I was just thinking ...

 

If the 4.3 fits so well in our cars, does that mean a 4G63 wideblock or G54B would just as easily fit in an older GM truck body like what the 4.3 came out of? I wouldn't mind having a 4G63-powered S10 to take to the drags, just to piss off the muscleheads.

 

Back to your project, I can't wait to see the final installation and first burnout. :D

thanks Joe... here are the motor mounts i going with, they are solid mounts for the 4.3. going to use a polly trans

mount to help with vibration.

i hope to get the motor and trans set in this week. speaking of the trans going to use the th400 with 3000 stall.

cant use the 700r4 because it's AWD :( i thought i could just swap the tail shaft but that wont work. would have been nice to have the overdrive, oh well.

 

i need to find someone to give me a hand on the wiring. me and electrical dont work well together...lol

I cant wait to see this thing man! Why not try and go with a manual tranny? just curious.

 

well i already had the th400 and the 700r4 trans i got with the motor. trying to keep the cost down as much as posible.

the th400 will have a full manual valve body, i could always swap to a manual trans later on.
