I'm replacing the stock 2bbl carb and manifold with a Sniper 4v EFI and aluminum manifold on the 351w motor in my '69 Mach1. The problem I'm having is hood clearance. The motor is stock other than a small Comp Cam. I got the Sniper and a Weiand Stealth manifold from Summit and before I even got the manifold out of the box I could tell it was too tall. Over 2" taller than the 2bbl manifold. I cleaned up the heads and placed the Stealth manifold on the motor to measure. With a straight edge across the tops of the fender the 2bbl mounting face was 7-1/8". The Stealth was 5", and with the Sniper setting on the Stealth with the 1" EGR spacer there was 3/4" to the air filter face. When I had the scoop off of the hood the middle hood hole on the left side had 3/4" to the top of the air cleaner. Looks cool, just doesn't fit. There's not room for the air filter to go up into the hood bracing either. Back in the day we'd just cut a hole in the hood, slap a Boss 429 scoop on it and be done but I'm not cutting this hood for a stock motor.
So the question to all those who've done this is, what manifold/air filter combination will fit at a relatively stock height or at least under the hood? My primary goal is EFI, not high performance as I use this for road trips. Almost any manifold I choose will improve performance.
NOTE:
The pictures are without the 1" EGR spacer between the Sniper and Stealth so there is less room than shown.
