4:45 ..... even though the ports look smaller here, the official holley/hooker video states it has a 1 5/8" cross sectional area. Either way, these are nice for mild 283 to 350 engines keeping that stock appearence, figure 383 or larger engines, stick with 1 3/4" long tube headers.
@@brad3139I feel a little bit in the low range from my 350 in the Chevelle for sure. The sound changed a little and its now deeper too. Im happy and they look fantastic and are noticably lighter.
I was hoping to get these to maintain the same connection alignment to the bottom exhaust system. Can you confirm that these manifolds have the same exhaust alignment to stock exhaust??

If you’re going to use these to replace the Rams Horn manifold you’ll have to replace your exhaust right? What’s the real benefit?
just got mine for my 73 camaro, goes in monday. I'm excited to see how it sounds and what performance gains come with it.
I'd like to see a dyno test holley manifolds vs headers vs stock manifolds
did you ever install them on your 73 camaro? any performance gains over stock log manifolds that you can tell?

Was looking for a follow up vid. Wondering how well they fit the Nova. Particularly steering box clearance on the drivers side. ?
I am definitely interested in picking up a set of these. I’d like to see what you think after they are on your nova.
After having these for a few months now, how do you like them? New exhaust manifold or headers will be my next big purchase for my sbc.
I guess you never installed them?

I don't know that for sure, but they look simular to the stock manifolds
Wish they were 3 bolt. There's no extension pipe to weld into existing pipe
Let's here them instead of rubbing on em.
Hi have u ran them yet?
No have not, I'll make a video when I get my engine swapped
@@venturahwy76 I just bought the same set. Did u coat them with anything?
@Guns & Gears I'm sure they should have washers . U agree?

@@lordsauto yes I would
That was 1 3/8" not 1 3/16"
