Gear drives…
Anyone recommend a brand- or not recommend a certain brand?
What brand is the loudest and which it the least? My motor is mostly stock, but I like the way they wine. (not sure if I want one that's too loud though.) s/t

Re: Gear drives…
They are all loud ... even the "quiet" ones.
The "cool factor" wears off very very fast and becomes incredibly annoying. I wouldn't recommend one for a daily driver. |

Re: Gear drives…
I put a Proform in my wife's '68 and it is noticeable but not loud. I think it sounds great and not annoying at all.

Re: Gear drives…
I got that one, along with the rest of the guts, from Northern Auto Parts. Their prices are really hard to beat.

Re: Gear drives…
I ditched my Pete Jackson, went to a chain. LOL, it makes a great paperweight now.

Re: Gear drives…
After looking into this more, I decided not to do the gear drive. Although the noise is what I liked it sounds like it will get old in a hurry.
So I inquired about a new chain system too. I’ve decided to get a stock timing chain system. Nothing fancy just a stock setup. The reason for this is because of the mileage on the engine now (116k). I’ll just wait until I redo the engine for the double roller unit or possibly a gear drive - after I hear some in the meantime. Thanks, s/t

Re: Gear drives…
I have the Eddelbrock noisy gear drive and its loud. My truck isn't a daily driver so I love it. Never heard that they rob horsepower.

Re: Gear drives…
My brother has a gear drive in his 65, it was cool for awhile. I have read somewhere that gear drives on daily drivers can have problems with harmonics (vibration problems) that can cause stress on the drivetrain. If I ever come across it I will post it up. It was pretty interesting. I did a quick google search but didnt find it.

Re: Gear drives…
I used to do a lot of V8 swaps in toyota 4x4s ( hence the CHEVOTA in skchevota) on the one I built four my self I used a pete jackson Quiet gear drive , I loved it. All though it could of been just the hole truck together that I loved, somthing about smoken 35"s on a detroit locked dana60 in a lifted rice truck with a heathy TPI 350 growling and a geardrive whineing going sideways down the street that gets my blood pumping. I do belive I miss that truck. any way I loved the gear drive...tobad I dont have any more V8s...although there is the old moter home in storage,hmmmmm.

Re: Gear drives…
If ya get the gear drive, be sure to get a torrington bearing for behind the gear drive. It protects the block from wear. Oh... and be sure you get a cam button - preferably roller to keep the gear from 'walking' your cam to far out of the block.
