Sheet Metal intakes
 

Ive got a New 632 BBC running with Ported Brodix BB3 Xtra-O heads. It has an Enderle Methanol Bird catcher and Edelcbrock Victor 2R Ported Tunnel ram.

If i change the intake to a sheet metal type (Hogans etc) and keep the Enderle Hat. Will i make more HP and Tourqe????

You may see some but I think ultimately the head you have is too small for the cubic inch. We are running that head on a 582. My buddy is running Dart Pro II which I believe are 380s on a 632 with the hat injection. He feels he is leaving a little on the table with that head as well. Are you trying to stay conventional headed?

we are flowing over 480cfm with this head after some alterations.which is more than a big cheif/duke at standard.

That is some serious work. What did you do to open the head up that much?

x2 At what lift are you gettting the 480? A CNC ported 365 only flows 460 at .900 lift.

Alot of metal removed and alot of quick metal put back in to reshape the ports. around 950 lift. about 2 weeks of development for the first port.

we are trying to stay with conventional heads. Sheetmetal intake???? 20ft lbs maybe????

IMHO, not worth the cost...........Stick with a good cast intake that's been properly ported and port matched.

Thanks. Thats all i needed to hear. I was always wondering if it was worth the tremendous cost or not.
