Here is what I just came up with with my Heads/cam install on a Mustang Dyno. You might be giving up 25 or so HP by not having the fast intake & LS2 throttle body

Put the car in first gear--Boil the hides for 60 seconds--if they go to the rims-no tires--you have gained 50 ponies--let is know-

Unless you dyno your vette all you have are guess's. And even a
dyno will show you a general idea in hp.
Good luck---I would say you have 417 rwhp. Right?????

All cars are different but my 2000 ls1 with all the same mods less vararam + Blackwing on ls1 stock heads with 918's puts down 405 rwhp and 403 fptq. Will be putting on the Texas Speed Heads in the next few weeks.
