Are you saying the new head is good for approximately 80hp alone with no other engine mods?
as a stock 9.2:1 comp 200 I6. peaks out at 179 Hp @ 5k, great numbers, considering running it through the program with just "low perfromance stock heads" which is factory set at 100 CFM at .100 lift and it figures that 4 times. it comes up with 109 HP.
He was saying 70HP (179-109=70) and I would have to say its a pretty reasonable assumption. When you see the head, you'll understand why.
However, to take full advantage of the extra flow, you'll want to change the cam too. I can't imagine anyone spending the money on a high performance cylinder head and running a stock cam.
We haven't dyno'd one yet, but we have ten proto types heading over in a couple weeks. Most of them are going to members with OZ heads, so we won't be able to get a comparison to a stock log head. One IS going on a motor that has a log head, however he's done almost every other modification you can think of. Including a 274 cam, Holley carb, headers, DUI dizzy, and all the tricks you can do to a log head. Its a far cry from stock, but it will be interesting to see the gains he gets.
are you going a have a distributor or two in oz?
Yes, Australian Muscle Parts will have them in stock. As well as some of our other parts, like the DUI dizzys, alloy valve covers, etc. I don't know what his pricing will be, as that will be up to him.
does that mean I might get a new 300 head for my birthday in Jan?
Well, their working on them, but I doubt they will be ready by Jan, more like Mar or Apr.
