potential flow #'s on stock castings?
what's the best flow numbers one can expect for a set of ported LT1 castings? I mean can they be made to flow 300 cfm or is that a little too much.....

Not sure if I've ever seen 300 posted for LT1 heads. I imagine you can with enough $$$.
Have seen several LT4 over 300.

Why the interest in peak numbers?
I'd be a lot more concerned with the mid lift numbers than peak, unless your car is at the upper end 95% of the time it's running.

Lloyd Elliot posted an interested thread about flow numbers and the importance of head design. Flow numbers aren't the only name of the game

I've read in several places that the early ('92 and/or '93) LT1 aluminum heads had more material and could be ported out more.
Anyone ever confirm that?

Re: potential flow #'s on stock castings?
I do know that 300cfm can be had as said above but lot's of $$$. I think AI has a set of LT4's that peaked at 300+ or so.. But on avg 275's or so out of the intake of a lt1 casting is the norm...
