Thread: A log of my updates on my '32 Brookville highboy

Sounds like a better idle than mine. I think it was a week from my first fire in the hole to driving it. Looks like your going to do it the following day.

Dueling 427's

The sound of music - (and probably one of the reasons I'm about 50% deaf)

Dave, It sounds great to me, too, but I'm only roughly 35% deaf (self diagnosed) since my left ear seems OK but my right ear is way down in reception. Loud music, loud cars, blasts of various sorts, working for hours in areas marked for mandatory ear protection without any. I hope the kids learn from our errant ways but I'm suspicious my deafness is hereditary since my kids frequently don't listen to anything I say. I recall it starts out as "selective hearing" as my wife puts it.

I purposely went with what I thought would be an exhaust "on the quiet side" with the two big'ish mufflers and I'm happy with the noise level so far, pending cruising for a long duration. I will probably post another video in the near future with the exhaust dropped and running open headers in hopes that it will stimulate my right ear and improve my hearing.

Bob, I'll head over there and check it out shortly.

I was sitting in the hot rod yesterday while the bomber seats were being fitted for me and I started it up, let it warm up, and then was reving it and just absorbing the sound and impact of this setup. I don't know if my words will convey the feeling which I hope to post up in the near future with videos including better sound quality, but my impression is that it sounds angry and violent and will scare most people. Perfect! Very nice!

Exhaust system and mufflers can tame the bark to a point, but the valve timing events controlled by the cam has a large influence on the sound. I've run three different engines on the same exhaust system, the 355 was a snarling, barking loud exhaust, the 427 much quieter and the 383 was a purring pussy cat. Here is the mild mannered 383....

I always like your vids, Bob. Thanks. Besides the "autocross" aspect of it, is there a name for an event like that? Would this be a gymkhana? If so, I'm keeping my eyes open for one around here.

So with some rain turning into snow tonight, and then possibly up to 4" of snow tomorrow, I'm not hitting the roads yet. Plus, the bomber seats are just getting final fitment tomorrow so I'm nice and comfy for long drives. Then that's about it except waiting on Mother Nature. Thursday this week and for that upcoming weekend they're predicting sunny and mid 50F's

I figured weather got you as I watched the national news. Gymkhana is serious drifting, tires spinning and no insurance company would touch that coverage among a bunch of bucket heads. To date, there just isn't any skill or performance contests we with bucket-t get to participate in. No drags, road tracks, or even parking lot auto-cross. Most all t-bucket folks don't care, their ride is shined up for shows, not designed and wrenched on for competition. I am the odd ball in that group. When we go on cruises, I'll never be the leader, but to make things more fun for me when the cruise is on twisty roads, I'll fall back so I can bank and crank the turns. Problem is the cars behind me after a few of these fall backs are no longer keeping up.

Nick, I got my 1st video up, it is really crappy, but due to your weather I got it up before you, here > My new baby arrived today

When stone cold mine is a bit loud, lumpy, and obnoxious, but once warmed up settles down. Still doesn't like to work hard below 2000 rpm, and after the 383 that takes some getting used to.

Sounds like it's getting there Nick!

I got my finned valve covers and air cleaner installed today. I realize the carb intake is only 5-1/4" diameter but I'm inclined to look for a thicker filter that fits between the top and bottom plate of the air cleaner. Otherwise, I really like how this looks on the motor.

Nick, I agree, it looks really nice!

Nick it looks great - but you will possibly have a problem. That little bitty air cleaner element is gonna strangle 427ci. I'm using the same size on my little in comparison 302 and you can feel it start to run out of breath over 4000 rpm. That oval element is from an '80s Pontiac Sunbird/Phenix 4 cyl engine 2.5L/151cid engine --------------------- pretty, but not too good for performance!!

I wish I could find my formula to calculate the right size.

Thanks for that info, Dave. I was on a fence about thinking if it was too small or not. First I figured that the lateral open area was quite a bit more than twice the carb throat diameter (filter is 11.5" X 7.87" X 1.87", carb is 5-1/8" diam. neck) but a few people have now told me it's too small so now I'm doubting my simple area comparison. I found a K&N filter that I think I can make fit and it's 4" thick vs the 1.87" of this one. It's the K&N which is 11.5" X 8.125" X 4"; I may give this a try but if it doesn't work it's a $55 experiment. Or I could look into stacking two of the ones already in there so double the height and lateral area. Other opinions are appreciated.


Btw, you can just about see the huge one I had on my old ZZ4 which I still have so I can use that until I figure out where to go with this one.




Btw #2: I still have these Sanderson Zoomies shown above (with all the baffles not installed yet) that fit the ZZ4 but since they don't fit the new motor I'm thinking of selling these. They're in perfect, barely used condition. Any opinions what they're worth?

Nick - there are several of us here that have been 'chartered' to help others spend their hard earned money

If that K&N works, let us know. I've seen that element but really hate to spend my own $$ on a whim I would have to turn my air cleaner 90* due to engine setback and the fact my cleaner is part way under the firewall recess, I would change it out though, dam' the looks.

That convoluted hose is 'gone'
