390 rwtq from almost stock 5.3
#33
I managed a 8.2 at Irwindale and 13.3 at Fontana in the heat. It is like people say Dynos don't mean anything they are just a tuning tool and to see if the mods you installed helped. The real measure is the track.
Also, the 408 was built with boost in mind so it has a 9:1 cr and I am running stock exhaust manifolds and stock intake/box. The numbers were from a load bearing dyno(Mustang and DynoDynamics) not a DynoJet.

Well, that is not bad for a 5.3, maybe i will dyno my 5.3 when it is done, i am shooting for 350 RWHP or so, not that it will reflect what the track times look like, but in a 86 TA with a stall and a larger cam, it will be fun. I really want to know what the little 325 is capable of with cam only, but i am cheating, using a carb. Unfortunately the shorty headers i will be using will hold back a bit, but i am chopping the collectors off for 3 inch pieces to do what i can to retain the ability to get the exhaust out as much as possible.
