F1A / LS3 Build-Up Give me your opinions on this build and if I need to improve it in some way. I want a nice easy and streetable 800rwhp. I want to run on 91 pump gas, so I plan on running on some meth most likely.
Brand New LS3 Block
4.065" Diamond -21cc Flat-Top Pistons
Callies 4.000" Stroke DrangonSlayer Crank
Callies Compstar Rods
TFS 235cc runners, 70cc chambers
MLS Cometic Gaskets, .045 quench
Now that should give me a 9.5:1 CR, is that correct and correct for this kind of build?
I am not sure on the rest of the upper end, like I have no clue what intake to put on this thing.
Tell me if I can improve it in someway folks, Thanks. Shane

I'd stay with the -21cc pistons which should give you about 9.57:1 SCR by my calculations. And that would be a great compression for a blower car. I think with that big 415ci and 13-15psi from the F1A should definitely get you in your desired goal range pretty easily.

Does anyone think that my crank would be a little Overkill for the engine? Would a regular CompStar Crank be just as good?

The Compstar crank will do just fine, I've never had a problem with them. Check out this build that we did, which is similar to what you're doing. http://www.exoticperformanceplus.com...Car.php?car=29 Bob
Also Bob, What CR do you guys shoot for in the majority of your builds? Or well this one or similar ones like it.

. In the future after its running and down the road I might even turn the boost up and aim a little higher.What intake should I run on this?

9.5/1 is what we shoot for. Thanks. Bob

There is a lot more power in it to be found. I am curious on what would happen if we swapped the Victor Jr for a FAST 92. We installed a cam that is larger than our standard blower cam, we're wondering if we'd see more power with our standard blower cam, and we have to chase down some belt slippage problems. Bob

I would opt for a 4.070" piston. The block already comes 4.065", and I would want a nice torque plate hone to make sure the bores are true. GM production tolerance is NOT race tolerance

I know I need around a -21cc dished piston. Will that work okay if its 4.070 bore?

you are bulding the setup that im ultimately aiming for. are you going to run meth?
if anyone can answer this: wouldn't going for a 9.0 cr be best? you have a enough torque from the bigger engine so i would think that aiming for the extra boost would maximize the setup he is aiming for? it would also help as far as traction on this street also,no? i would like to know this for future reference also.
to the OP, i would look for tick performance an their t56 build ups. they are priced very well. give josh a call
