If i were to ever see this vette and looked at that motor with the car off, i wouldnt even think it was a 500RWHP car. Sneaky motherf******!!!
so im guessing with a forged rotating assembly and aftermarket 13 or 12 degree (or 11 if you really have extra $$$) heads, close to 600RWHP is likely very doable N/A and probably the limits of a N/A LS3 without using laughing gas |
While it is a nice setup and 570rwhp are believable, BUT 604rwtq? sorry but no. Dyno is off.
It trapped 128-130mph, which I think is not enough to reflect 574rwhp in a lightweight vette. Maybe its a slow track, harsh DA, idk. Vette with hyd cam only ran as good with no more than 475-480rwhp(realistic number). https://youtu.be/TjmYvs8J2Gg like this one, and trapped 128mph too. Its not 130, still you gain more than 2mph with 100rwhp more..
But still a big solid roller or hyd cam, ported heads, high comp ratio and a matching intake(short runner), close to 600 is very doable.
