    8010 is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from Great addition! 1978 F150 4X4 351m C-6 I bought this in November 2018 during the online sale. I installed it with only minor modification to my engine heads. 1st day - Had to remove/grind 2 pins/dowels flush on the heads to dry fit it in. Used an engine hoist to remove the old intake and thankfully I did because of the weight of the original intake. It weighed a lot. Installed new intake without the engine hoist with valley pan and a bead of grey gasket maker instead of the black gasket provided. Torqued bolts per specs. Allowed to dry and set for at least 3 days since I needed to finish the install. 2nd day - Installed Holley 600 CFM 4 barrel carb. Installed transmission kick down cable and relocated carb spring. 3rd day - Installed new brake booster line to intake. Installed new inline fuel filter and then cranked it up. This is a great upgrade to my 351m engine. I thought there was a bent rod but it was actually a leak on the back end driver's sided intake gasket. What a difference in power and performance. Still can't get over the difference in the performance of the engine.

    Rated 5 out of 5 by from 351m build Installed on a f150 351m. Good fit just have to remove the alignment dowels for the stock intake. Small piece of aluminum inside of intake from manufacturing process but overall good fit. Very noticeable power when paired with an Edelbrock Performer 1406

    Rated 4 out of 5 by from Good value Only problem I had, had to modify accel cable bracket and it didn't have a bolt hole for the ignition coil, but was able to put a stud in the intake bolt to make it work. So,overall, satisfied.

    The intake says its for the 351m or 400 with 2v heads, being that the 351 cleveland is essentially a 400 with a shorter deck height would this intake fit on it? Would it work with 4v heads? I thought the only difference was the combustion chamber shape?
