Okay to go along with this subject...
I have a friend who has the same year Galaxie that is sort of a bastard car.. much has been changed on it from the previous owner that he was unaware of....
Before I met this guy he had made some modifications to it on the advice of some other poeple that didnt really know what they were talking about. He has been complaining about not making enough power. He has a 390 FE engine that used to have a 2BBL carb he replaced the intake with a 4V manifold and is currently running on stock Cast exh manifolds. Also he has replaced the cam with one of unknown specs but was told that it was "high performance" He is running a C-6 trans, and a 3.00 9-inch rear axle with a detroit locker.
I know a bit about engines, but mostly I am a chassis designer/builder/tuner....
anyhow he asked If i could look at it for him so i went to look.
There are some things that bug me about this and maybe you experts here will pick up on this right away...
the engine runs smoothly, but the timing is about 40 BTDC w/o the vacuum adv. and around 60 with out any detonation occuring at all. The car does not produce enough torque to break the tires free. now I know that this is not the best platform for a race car and all, but he just wants to be a kid with it and burn rubber when he's cruising! lol
anyhow aside from the obvious... heavy car, small gear and stock exhaust.. what do you think...
The timing, just doesnt make sense to me.. is it possible that the cam is indexed incorrectly, perhaps retarded by a tooth? Would that make it possible to have 60 degrees of advance without detonating?
We are going to tear the engine down when he puts it away for the season at which time I will slap a degree wheel on it and verify the cam timing and review the profiles
I have told him all about the other things he needs to do.. I.E ignition system, weight, taller gear, new manifold, bigger carb, headers,
he loves the car, and just wants to show off with it.. not race it.. go figure!
any ideas would be greatly appreciated JonnyB |
