Naca Hood with aftermarket Intake manifold
#1
I picked up a Naca hood for my 351w car and have been looking to do motor upgrades to my car and I've been looking at things like the Edelbrock top end kit, but it includes the Victor JR intake. I want to know what options I have that won't interfere with the way the hood operates.

Because the 351W was never available from Ford in a 71-73 Mustang it may be hard to come by specific recommendations for manifolds that fit. Since the deck height of a windsor is taller than a cleveland (+.288?) I suspect your options will be limited due to hood clearance. If the engine is in the car it would be best to measure what the hood clearance is now and then using the manufacturer's dimensions for various intakes you are considering, calculate whether or not they will fit.

Do you plan on making the hood functional?
A Victor is tall on any engine, under any hood.
Does your engine build really require a Victor?

Keep in mind carb spacer and gasket heights, if needed, also.

I know this combination doesn't resemble your build, but I just got done upgrading my 351c 2V: replacd the stock Intake manifold and 2bbl carb with a new Edlebrock Performer Intake and an Edelbrock Thunder series 650cfm AVS carb... and the new setup is actually shorter than the stock setup. So when I go to install a functional Ram Air kit, all I need to do is fine the right siz spacer to go beneath the carb.

I do plan on making the hood functional, and I wasn't specifically looking at the vic Jr except it come with the edelbrock top end kit. But I knew it was taller then a OEM or even many aftermarket aluminum manifolds.

Not quite true Tommy but mostly true. A few 351w engines made it into the 1971 351 2v H-code cars. There was no distinguishing which car got which motor. The factory had excess 351W engines available so they were installed into the 71 mustangs without rhyme or reason until they were used up and a steady supply of 351C engines became available. Source is Kevin Marty "Mustang by the Numbers".

As far as intakes go for a 351W and ram air there are several that will work. My favorite is the Weiand Stealth.

Ford put windsor / c4's in 72's also.

I wouldn't doubt the 351w in a 72. There were no records or identifiers in the VIN to differentiate which car got a 351 W or C. All the 302s are W engines; so yes, Ford definitely put Windsors in the 72s. Tongue

For trannys in '72 there were:
6,373 C4s mated to the 6cyl engines
24,976 C4s mated to 302s
34,058 FMXs mated to 302s
All 351-2v with auto trans received FMXs
All Q codes with auto trans received C6s
