That should be great on fuel economy

How would it effect it?
How do you increase fuel economy and hp at the same time, doesn't it normally require more fuel consumption to increase hp?
Surely your not just trying to create drama on a tech thread as opposed to just answering the OP's question?

Lif the port is more efficient, power will go up without an increase in fuel economy.

I struggle with people wanting to make power but think they can make X amount of horsepower without burning fuel.

You can't save the world. We aren't out of oil. There is no such thing as man made global warming. Build what you want. Let the freaky people worry about shit they can't control.

If I were you I would get some 195 and full them in till they're about 160cc.

Then when you want to go faster you can grind them out to 230cc

Well, an LS3 does it with less bore, less stroke and 260cc heads... Is there really that much difference to what they do VS a gen 1 SBC based engine? Why couldnt you adapt the same philosophy and build the same style of engine on the older platform.

id just ignore the headcase, he is flat wrong.

For power brakes to be useable and to extend clutch life stick to 218-224 @ .50 106-110 lobe separation.

I was being sarcastic to the cam salesman

Use italics for sarcasm, just to make it a bit more obvious...…...

Yes I figured, I couldnt understand how a 220cc AFR head is too big and the 195 is fine when the difference in cross section isnt that great what would it be .125"-.150" or something. Put the same cam in as the 383 with 195cc head example on the 406 with the 220s. what would make one great and the other a disaster?

No, he's correct!
Didn't we just go through this same argument a couple of weeks ago in a 195 vs 210 thread or something? Lol

Lol.. apparently you can't even guide a donkey to water.

Oh well moo moo it.

Once you've been on both sides of the coin there is no denning that a slightly under Camed street / strip car is fun to drive 95% of the time where as a slightly over Camed car is not fun to drive 75% of the time!

You don't have to over cam it if you use a good cylinder head!

Interesting
Most streetcars I’ve done last few years are 270-280s. Some 280-290s. And these dudes love driving them weekly
Lol
