FAST single plane inlet manifold SBC

[Webby]

Considering converting my EZ-EFI Throttle body injected engine to individual port injection. Current inlet manifold is victor junior port matched p/n2900 which goes well with my AFR 210 CNC heads. Anybody know what port dimensions the FAST single plane manifold has and also its height as I am severely restricted under the hood.

It is the Edelbrock EFI intake, Victor EFI.

Yes Brian. I have found the Victor however port sizes seem to be a lot smaller. Do they do a port matched version?
I have also found one by World products about 1 inch higher though. Not sure if it will fit under my hood.

The Fast is the Edelbrock intake. No they don't have a port matched version. Too many different head combos so they leave it to you to finish. I have the same Fast intake on my daily driver 283 Nova Wagon.

OK thanks for your help once again. It is difficult to get Chevy stuff here in the UK. I have ordered a Victor EFI from American Speed who built my engine. They are going to port match it to the AFR CNC heads that I have on my engine. This is to convert my EZ-EFI throttle body to individual port injection. We have discussed it before. I need individual port injection in order to run the racelogic fuel cut traction control system that I have. Having installed that the next question is whether to go to XFI and sequential injection. Your comments appreciated.

The XFI and sequential is a much better ECU than the EZ EFI but also cost more and application for it is different.

Sequential is often not really needed, I ran a Fast classic on my drag car for for 4 years with a bank to bank mode and 160 lb injectors. Last year I switched to the XFI and ran it in bank to bank for a couple of races then switched to sequential. It does spool the turbo faster in sequential than it did before but in overall horsepower and et at the drag strip that only changed .002 faster.

Big injectors and a small engine I think there is a benefit to running sequential. On throttle and off throttle it will help also.

OK Brian so I fit Victor EFI with 8 injectors and bolt a FAST 307603 throttle body on to it. Where how do I fit the IAT and the MAP sensors? There does not seem to be provision on the throttle body. Or am I wrong?

Fast throttle body (not ez efi) has a vac line on the back side of the throttle body. Intake air can either be drilled and tapped into the intake manifold or in the air cleaner.
