[quote=fast68plymouth]On the two stroker motors I dynoed that had Indy heads and a x-ram intake with edelbrock 750 carbs, when jetting for best power, I ended up with jetting quite a bit richer than the as delivered edelbrock jetting.
One was 675hp, the other was 745hp.

One of those came to me with torched head gaskets from being run too lean.....and those carbs were richer than stock as well. [/quote
Were they the stock mani or aftermarket, my jetting comment was based on the stock mani. Some of the NHRA Maxie stockers are near the 650 HP range and not varying far from the factory jetting that was right for the maybe 400 they made stock. I'm guessing cam design, aftermarket head and mani ports and large headers make this a different animal. I could be wrong but IMO that motor that burned the head gasket had some other issue if it required much larger than stock jetting.
