351C-4V Edelbrock Performer vs Blue Thunder intake comparsion & Fitech.

Took som photos of the difference between the Performer intake (idle-5500rpm) and the Blue Thunder (idle to 6800rpm).

The Blue Thunder is about 1" taller in height and are considered as an semi hi-rise intake.

Also i took some pics to show the size difference between the intakes and also show how big the intake runners is on the 351C-4V cylinder heads.

Here is how i was planning to run on my 351C- 4V CC earlier.
Edelbrock performer with Edelbrock 600cfm and a 1"spacer.

Here you can see that the Performer intake is sitting about 16-17mm
below my valvecovers wo a 1"spacer.

 I have no pic of it but the Blue Thunder intake is sitting way above my valve covers. 

I think the carburetor flange and the intake floor is about 1" (25mm) higher than the Performer intake.
