Ok so after 17000 miles on the new L92, milled heads, Comp VVt cam, springs etc etc, i sold my LT1 Trans Am and with the money I bought a LS3 based stroker.
My new setup consist of a LS3/ L92 block, Scat crank, Scat rods, Probe Pistons, a set of TEA stage two L92/LS3 heads with the double springs, ti retainers, and 73cc combustion chambers. Lunati cam, Comp short travel lifters, Yella Terra Rockers, MSD coils, melling hi vol/press pump, and I am finally gonna put the Vig 2800 multi converter in when we change the engine out. Truck still has stock 3.42 gearing with the 6L80 trans. I will also be stepping up from the 1 3/4 OBX headers to a Kooks 1 7/8 header, same Magnaflow 3 1/2 cat back.
There are a few things I would like to get opinions on, like throttle body and intake thoughts. Injectors, and what do you guys think happens to a cruise @ 83 17.4 mpg and cruise at 70 almost 19mpg fuel economy.

 

So I think this subject has been addressed before the actual effectiveness of the truck L92 intake. I have seen flow nyumbers of heads being flowed with the truck intake compared to the LS3 intake with heads bolted; but has anyone actually swapped and know if there are any tradeoffs in low end torque with truck intake and FAST car intake. Also is there a method of porting the truck intake to accept the 102 mm throttlebodies? My cam timing is mild to keep torque everywhere in the rpm range, but I would like to make the best of the ported heads I have had TEA port for me. Spoke with LS2 portworks but our intake is no longer availablke as a porting option through him, what do you guys think? Also I have saw where LS7 users are making 630+ hp with a stock injector, how does our L92 injector compare to the LS3 or
LS7 injector. What do you guys think. I have a week and 1 day to get these few options figured out, as I plan to finish the assembly and get this engine swapped out by next weekend.
Thanks guys for any thoughts!!
