| RE: Don't Lose Your Head |

The flow numbers are from memory mostly, so I'm sure I'm off a bit. What I remember is, stock Windsor heads stink. Most stock alum heads were in the 200's. Some stock alum heads made it to the 300's, but those were race heads. With porting, the numbers obviously went up, but the same should be true for any head.
Someone on the moderated forum had his CJ and Ed heads flowed. I've got all that in a spreadsheet. It was interesting that the Ed heads flowed almost exactly the same as the CJ heads. Now, I know the flowbench isn't the end-all. The head material may favor aluminum (or it may favor iron!). I also know the Ed heads have relocated valves and spark plugs, and they've got restricted oil to the rocker shafts.
What I'm mostly interested in is real-world power differences between CJ and Ed heads. I've got a set of both with the Ed heads currently on the car. It may not really matter which set I use since I plan on doing a mild port job on whichever set I use.
I would be interested in your flow spreadsheet. If you e-mail it, I'll reply with the small spreadsheet I did.
BTW, I wasn't slamming the FE for less than stellar flow numbers. I just expected higher numbers given the reputation of the 428CJ, 427, 406, etc.
One more thing. When I was in high school, I raced a 302. I'm not sure what rpm I shifted at. I ran a tach for a while, but it said I was shifting at 8,000. That's hard to believe, but I'm sure it was over 6,000. Yes, the tach was installed correctly. I've had my 428 up to 6,500 already with no worries of blowing it up. I knew several people that threw rods in Chevy 327's and 350's. The Dodge's had problems shearing lug studs. They'd be driving down the road and their back wheel would fall off. I had problems with blown head gaskets and spun bearings. The point is we all had mechanical problems. It sounds like the FE's biggest reliability problem is the rocker shafts, and that's easily fixed. The Chevys rarely won (when I was in high school), and when they broke, they broke rods. Now, everyone thinks the Chevys have the strongest engines. I guess we have NASCAR (and Ford's no racing edict) to thank. |
