I currently have a 99 RCSB with Whipple Charged 4.8 and LS1 heads. The motor has 137000 miles on it and am getting sick my current setup. I am thinkin of selling the blower and my 4.8 and buying a low miles 6.0 to replace it with.
Depending how much money i have left over I would like to get a cam for the 6.0

My Questions are: Whats my blower worth? Its single belt with vaccum bypass.
Whats my motor worth?
Will the 6.0 with a good cam make more or less power than
my 4.8?
Please help!!

 

What's your current setup making power wise? What kind of times are you putting down? Any specific goals in mind? I'm pretty fond of the 6.0L swap myself.

 

What about picking up a 6.0 block on the cheap,
lowering the CR a bit (maybe just new pistons
& rings?) and keeping the Whipple? Maybe that
would just need a pulley change for the higher
displacement? Or are the Whipples sized different,
for different apps?

 

I'd go with a cammed 6.0 hands down.

 

Unless you fab up an intercooled whipple, I would do the 6.0 swap also.

 

WHAT SIZE LIFT IS YOUR CAM AND DO YOU GET GOOD GAS MILEAGE. AND WHAT IS YOUR MPG.

 

There is no substitution for cubic inches.

 

Sam~ keep the 4.8l. Get a real power additive and then you will be all set. That thing is fast enough for you anyways Besides you never even gave my 4.8 a run for its money
