Id shure like to know.

Well, For those that are curious, the motor is in and running. Due to a series of unforseen events, I am currently using the peanut ports with stock valves, no port work. The combo is as follows:

65 Biscayne, 4000# (?)
454cid, 9.35:1cr (approx)
770cfm Holley SA, vac sec
Weiand DP intake (rect port )
GM 14092360 Heads "peanut ports"
Voodoo 60201 Hydr FT (256/262, 213/219@.050, .515/.530, 112LSA, 108 ICL)
Headers, 2.25" dual exhaust through 40 series FM's
TH400, stock converter, 3.36 gears in the rear diff.

How does it perform? Depends on who you ask. In my experience, it has very good street manners, starts fine, idles fine at about 700 or so, only a slight lope. This combo provides an exessive amount of torque just off idle and pulls very hard (IMO) up to about 5000 (highest I have revved it) although it gets a little soft starting around 4000. It will burn the tires for quite a distance if I ask it to.

Let me add, I AM NOT A DRAG RACER AND HAVE NEVER DRIVEN A SUB-ELEVEN SECOND CAR THAT "HOOKS"........SOOO, to some people, this car could very well be A DOG (or "turtle"...some dogs can RUN) and thus not very impressive. For saturday nice cruises and tire smoking to impress the chics, it does just fine.

The "dreaded" peanut ports are performing better than expected. To compare theory to reality, I can feel the choking effects start to come on around 4000 like I said (and like others have told me) BUT it is not nearly as bad as some would lead you to believe. Could be the exhaust?Again, JMO. Depends what you are comparing against. For such a heavy car, it moves very well. City mileage, with my foot in/out of the throttle, netted around 8.5mpg. Highway MPG I would guess somewhere around 11 (?). I havent driven enough highway miles to know for sure.

Thanks to all who helped me get here. If anyone has any questions or comments about this motor, feel free to PM me or reply to this thread.
