Weiand 8120WND Action Plus Intake Manifold

First off, I'll say I'm very happy with this intake overall. It is a Street Warrior intake, NOT an action plus. The high and lows are as follows:Pros:-NOT an Edelbrock-very well machined-two tapped ports in the front water passage, great for a block heater return-Needed minimal port matching for my heads-Lighter than my factory aluminum intake.Cons:-Cast in china, machined in the US (just like all new edelbrocks, but without the made in usa stickers plastered on it)-no rear water passage. My factory aluminum intake didn't have them either, but it had solid flat points that could be tapped for a crossover line, this intake does not-Throttle linkage mounts did not match up to factory linkage plate-distributor hold down relief didn't match the factory hold down..minor annoyance, but it took me a bit of time fighting with various bolt lengths til I had one that would fit OK. Could have cut the back tip off my hold down, but would have lost the "loop" for the bolt to go through and would have just had a U, didn't like that idea.-Alternator bracket mounting points were 3/8" off from factory. Plan on enlarging the bolt hole in your bracket.-A/C compressor mounting point (R4 compressor)was about 3/16" off from factory.Overall, a well made intake with a few minor installation problems, nothing that is completely unexpected with an aftermarket "universal" part.

There are more then one type of 350 small block Chevy engines. Mine is a 1972, 12 bolt manifold but there is an 8 bolt as well. It fits but holes don’t line up, supplier was great, no hassle return and got the correct one in days.

Installed in 1978 corvette. Lots of air cleaner options. This is .5in less carb pad height than edelbrock square bore. That half inch comes in handy. Replaced Qjet on edelbrock manifold to this with edelbrock carb. There is enough height with drop based cleaners. The stock cleaner will fit with short spacer but the front vaccum actuator on left side is real close to hood.

I've been wanting to upgrade intake on my classic car for a long time but wasn't sure of performance gain........finally upgraded with this Weiand aluminum intake and WOW WHAT A DIFFERENCE!!!!! I highly recommend this intake to anyone looking to get better performance from their small block Chevy engine. It also improved my gas mileage!

Nice simple intake. Excellent price. I did have to remove a big chunk of aluminum from an intake runner. (casting defect)

Recommend to anyone thinking of upgrading to an aluminum manifold for street use, easy install, no problems with threads or holes lining up. Crisp throttle response (used with Holley 1850)

Center 4 bolt holes machined wrong for 88 c1500 with factory iron heads... Even if they weren't the setup of this intake would make it very hard to properly torque the center 4 bolts.
