So I quickly realized that the adapter for the Holley to Weber is for an approximately 36MM bore, the Sniper is 40mm bore, no biggie, I have to get the intake off and hogged out, so I will get my guy to make it bigger at the same time. I am pulling off the intake tonight (hopefully) to get my guy to work on it tomorrow.
The height seems ok, the EFI with the adapter is about 10CM to the air cleaner mounting surface, I measured the Weber to be a bit over 11CM, If I were to include the adapter I use, it would add about another CM on top of that because my adapter sits proud of the lip of my 32/36. So air cleaner clearance seems ok.
So it is kinda like putting a 40x40 DGV Weber carb... The question will still remain if it will flow properly at idle. Because the Sniper is synchronous and the 32/36 is progressive, It will be that more fun to tune.
Here are some measurements of the height of the sniper vs a regular 32/36. Enjoy, I will post some pre and post pics of the intake.
