Ls3 head flow numbers Ive looked everywhere, but I don't see any consistent Ls3 flow numbers. What im looking for is: flow numbers for PRC ls3, stock ls3(0821), GMPP ls3, SDP CNC ls3 and any other ls3 heads at comparable bores. I just saw someone that showed their flow for ls3 heads on a 4.030 bore and compared it to Texas Speeds CNC heads but the stock 4.030 flowed better..., this is why Im looking for some accurate numbers.

Trying to find good data on a 4 inch bore is tough. Many list numbers on a 4.125 that makes them look better. Look at MAST, I believe their small bore LS3 offering is on a 4 inch bore.

Please see the attached hoping this will help...
As advice, the flow number will be usefull if you know the cross section area of the runner to determine the velocity.
The key is velocity.
I wish if they could post velocity (m/sec) instead of flow (m3/sec)
Thanks
