I'm interested in a set of '04+ FWD heads. That's when they increased exhaust valve size and revised the exhaust port. I'd like to see how the '04 exhaust port compares to the intake. The int/exh ratio on the '00-'03 heads is attrocious for an all motor performance build. It's too bad because the '00+ intake ports flow excellently.
Beyond that, I have all the major parts I could ever use. I've sworn off production rods. Eagles are soo cheap and soooo much lighter that there's no point in using the stockers. Alan Johnson told me that the stock rod bolts wouldn't take much more than 7K reliably and the stock rods should be replaced to spin the engine to 8K reliably.
The '00 engine I took down tossed a rod with ~50 miles on the clock and the '96-'99 was a dyno mule that had holes poked in the cam covers and lower crank case so it couldn't be sold as a new engine.[This message has been edited by Will (edited 12-31-2006).]

The two guys had complained about are janitor about a month ago. Two weeks ago they sent the motor to our part time/retired parts guy. That means he was in the 19th and then I would think he took home the engine on the 22nd. He scraps the aluminum for doughnut money. The prick that had the engine in his stall said I could not touch it, because he was selling the parts on E-Bay. Six months later and no motivation on his part the engine was given to Jake. I have helped out Jake and his son a lot. I will see if they have the heads yet. They will give them to me if they have them. I will let you know.

Hello Will
I looked into moving the Intake cams. The company that did the head work was BPE racing heads. They had refered the customer to CHRF. They say that they set cam centerline up different.
For the normally aspirated engines, we have 5 grinds from mild to wild. These cams will still make enough vacuum to operate your power brakes, etc. We also set up the intake centerline a little differently to obtain more torque or more power.
272 deg
280 deg
288 deg
300 deg
310 deg
Stock for a VIN 9 was 122 +18 "1 tooth" = 130 DEG.
Something to look at

Did the head work for what? LMP cars?[This message has been edited by Will (edited 01-12-2007).]

99 Y engine has intake cam timing at 8 deg BTDC and a centerline of 117 deg ATDC
99 9 engine has intake cam timing at 13 deg BTDC and a center line of 126.5 deg ATDC
2000 Y engine has intake cam timing at 5.6 deg BTDC and a center line of 113 deg ATDC

I remember the post. I'm still wondering what that has to do with BPE.

Those are durations, not centerlines. Stock for a VIN 9 is 266/24x Intake/exhaust. You can't change duration by moving the cams.

Want me to keep an eye out for those heads? I scour ebay pretty regularly...
Strange, I too had a 2000 with a rod sticking out of the block... The rods (or rod bolts, not sure which) appear to be a secondary weak link, after the head gasket/head bolt holes

Go ahead... keep an eye out for them.
The Y2K engine I tore down had the rod bolts intact. I'm not sure if the piston came apart or if the very end of the rod came off.
