I threw the Mildon gear drive out of my big block when I found metal shavings coming off the gears when I went to retard my cam a little. They also induce valetrain harmonics which lead to early valvetrain failure. I am an avid fan of Rollmaster timing sets now...

Shane the last geardrive I was "involved" with actually retarded the cam itself 2 deg at the cam (4 crank deg) after only 10'000 km's or even less, But it was a popular $270 cheapy from sydney ,since then I wont have anything to do with them.

cool just check the pins that the idler gears run on, Where they line up with on the timing cover cause thats where mine kept drilling.
Me personally I would just get a double row timing chain like a rollmaster series. If you want the noise either buy a blower or a set of gilmers. Anyway let us know how you go.

you cant run the normal mechanical fuel pump on a clevo with the gear drive , so youll need a blocking plate ( easily made ) and electric fuel pump/s , regulator etc Yes you can, you can run a mech fuel pump with a gear drive, mine runs just fine (for now at least). Ps, Didnt end up buying the Holly elec Fuel pump, decided not to, but i got lots of valuble info on it - thanx.

on my gear drive i couldnt bolt on the eccentric ring for the pump to run on , i dont mind , im happy with the electric twin fuel pump / filter set up ive got
the cam i want means ill have to get another set of v/v springs , it,l coist about $900 for a cam change - so ill have to consider it a bit more i think as ive just put deposit on house and 3 kids / holidays cumin up |

did your gear drive crap itself?
im really confused now about this geardrive situation. i think i might put it in for a while and see how it goes, and then check it again after x amount of k's then if i see early problems ill chuck a chain in it. thanks for all the replies, as i keen to hear both sides of the story. also with my gear drive, i got these "bush" things that have off set hole drilled in them. and they slot into the top gear, i think i thas something to do with the camshaft? |

checking after a few thousand ks is the go i think as some walk and cut into the timing case.
i had to grind some of the idle shafts to sit squarely the bushes are to dial in the camshaft -which is cheep power and keeps everything running smooth, to do this youl need a degree wheel ( and a dial indicator (preferably) a engine builder can do this for you at little cost |

yeah im thinking of taking my engine to a shop and giving them all the bits and go, "can you put this together for me?" and see what they say, then i know it would be done properly, but i really want to build this engine myself so i can say, yeah i built it, all of it, and this is how well it goes.

i say go for it Mate, i did it & and couldent fell better about it, i set out to make a nice simple Hway cruiser - that will last me for years - and thats what i ended up with, and if somthing major goes wrong with your engine - you will have a better understanding of whats gone wrong and how to fix it your self, good luck. oh and Pinkbits, sorry to here about your Gear Drive, i always thought they were better than timing chain.

itll cost too much at a shop , but they will do it right
i do them myself- a bit scary when starting as theres no warranty, but yuoll feel better that youve done it yourself i build from a book - rebuilding 351 / 400 / 429 /460 fords or something i got a cloydes premium chromium double roller chain set for $170, im hoping that wilkl do the trick |

yeah ive got Tom Monroes how to build ford v8s 351c-351m,400,429,460, and i think its the best book ever written. it just makes things so much easier to understand. im going to build it myself as i think the personal pride is worth it alone. i might get professional help when it comes to installing the camshaft tho. at the end of the day i dont think its too hard really, and if im patient and careful it should turn out well. well thats the idea anyways!
I hear pink bits will be at the summernats this year? if so ill have to catchg up and have a chat to you! |
