540. Cam is going to hold it back. Could get closer to 600 with the right cam.

750's are for small blocks.

Ok so lets say I do the mill on the heads. What cams are recommended. It looks like the 731 is slightly smaller than mine now. And from research I dont have queit enough comp to swing the 741 and maintain bottom end. How much lsa can I really get away with since I have dry to tip exhaust

At 9:1 or better you'll be fine with a 741. I'm going slightly larger on the same compression albeit 502 bottom end. Remember a 741 is the same cam as 525 except it's on a 112 Lisa and 525 is on a 114

Is the 741 the best off thecshelf cam for my setup or should I take advantage of the lack of reversion and look in the 108 lsa sizes

Is that cam pretty small especially for a single plane manifold?

Edit: I was referring to the original cam.

I originally built motors on budget with intention on doing heads later. Originally it had l29 vortec heads 99cc chambers pocket ported and rpm air gaps with those cams. Spun bravo 26 to 71 at 5100. Good runner for what it was.

Like I said I'm running a larger cam with a 502 base. EQ heads. I'm gonna mill .030 to compression around 9:1. I'm using merlin intakes and QF 850 carbs.
