The 2v is no different but with smaller ports and less hp capability. I see no reason why the oc head cannot make 600 hp. Infact my guess is the ol boy’s probably ...

A buddy bought the other. He has problems with it being rich also.

Rest in peace Pat. I’ve used your book as reference many times. In fact wore one out and bought new copy. Lost a dear friend it feels like.

If you are pulling oil from valley your intake ports will show signs of oil residue. Especially the amount it’s using.

I have two of those qft1050. You have to check and make sure its not for a boost motor. Mine were and that requires adding a vac line for it and adding power valves. Otherwise they run way rich.

Finding a flat tappet core might be next issue. Last two Clevelands im doing roller cores only?

It definitely was in the 90’s when i talked with this guy. Do not recall his name. Was excellent to talk to and got a lot of information from him.

It could be mag. Im not exactly sure. We actually ran the engine with k&n stub stack filters. When i removed the filters and just ran bases it made 712@6700. The car is a heavy tub so we tighten duration hoping to get this land yacht outta gate better. Just going to stuff in.

I remember when i first bought the kbs I talked to there tec for some info. He told me his own 347 stroker was the test mule. They had a 350 shot of nos on it and it worked awesome. As mark mentioned he also stressed tuneup tuneup tuneup. But thats like everything I suppose.
