Siamesed Intake and Plenum;
441rwhp and Torque 373 ftlbs Enlarged Plenum(+80ci) with Siamesed Runners: 426 RWHP 361 ftlbs Any thoughts? 36MM all the way through siamesed stock intake with Siamesed 1" at top and bottom of runners? Buy a LS7?

and the cost of the build would almost be as much as a z06

more cubic inches or a different cam profile? Perhaps a different header design... Is there a specific rpm range where the torque becomes less on the before and after tests?

Whats Next?
Use the LT5 for a boat anchor. Install a LS engine and enjoy. |
