L92 flow results with manifold.
L92 flow results with manifold. So we did some touching up on some L92 heads. We opened up the exhaust and just barley touched the bowl area on the intake side. The radius to the seat on the intake needs some attention to it, but thats all. These results were done on a superflow 600 bench, 4.100 bore, 28" water.
No manifold

With manifold
.100_67 .200_153 .300_224 .400_268 .500_301 .600_323 .700_323
Exhaust was done with no pipe. So numbers will be lower than if there was a pipe on it.

Hey Rick,
Thanks for the info. Was the intake the GM carbed manifold or the EFI manifold?
Did you do any work to the manifold to get it to flow so well on the heads?
Thanks,
Glenn

Marginal......... looks like the intake flow numbers equal cathedral port numbers with no intake. My L92 and L76 are ordered.
I think there's going to be a bunch cathedral port door stops laying around in the near future.

Good stuff Rick. Need to send that intake off to Mamo to have him port it. Might be some further gains!

The only thing that sucks is that the intake is a one piece unit. Not sure how much meterial is in it.

I am not sure if you would even call it that. More like fixing something.
