that's awesome,now take it back off,make a couple dozen duplicates,and sell'em on ebay and make your money back-george
You're about a fabricatin' motherfucker. Excellent! Now about this rope, It seems I'm all out. Could you send me a piece? Billy
So, ummmm, ahhhh, are ya gonna put up the plans, there's a Biscayne I know that has a 235... Way to go! I hope FatHack didn't have a hand in it... Jay
Very sweet, way to make what you can get cheap work! With your permission gonna have to steal that one for my website, know 2-3 guys that have bitched about the price of the original style one's that will dig it. MONGO
nice job. it looks kind of cool hanging way out there parallel to the motor too. shows off the mechanics I thought there was some "science" to the size of a vacuum cannister but I could be mistaken. If it runs good that sounds like the right size to me.
That looks great except step #4 is questionable. That bracket is there to restrict the distance the rod is allowed to move and therefor how many total degrees the advance advances the distributor. Maybe the whole available travel just happens to be the right amount, maybe. If it ends up advancing too far and pinging at no load cruising speed then you might need to add some ofthat frame back on, just not the whole thing that encircles the rod. It isn't going to relate the same as the dissy it came off of because the 6 cyl distributor arm is longer so it needsto move farther, but on a different application it might need some of the frame left on. KnowhatImean?
you're not that bitchy i gotta admit,sometimes i get sucked into the drama,but i'm really here for the tech.no,really
[ QUOTE ] Boy that sounded bitchy didn't it? seriously, if anyone wants to chat a little about which vac advance for which engine....then I'm very interested. Is there an equation or formula something for this? Thanks again fellas for the compliments and all.. VT. [/ QUOTE ] dude were you bitching at me???? I'LL DROP SCIENCE on your ASS at PASO!!! LOL (kidding/drama) but seriously/tech... The size of the can/diaphram? relates to the curve of the advance. I think I read something about the sizing of "the can" in one of my inline books I will search for it when I get home tonight...or someone here must know the "formula" ?
no hard science yet but I found this instruction manual for the crane adjustable canister that sheds a little light on how it works. (learning myself too) It just talks about listening for spark knock. http://www.cranecams.com/pdf/254g.pdf "For maximum performance it is best to run as much vacuum timing as possible without spark knock."
You're welcome, glad to help out once in a while. Also glad that my buttin in on stuff occasionally helps out. Now can I go back to the dissing VDO O/T thread? and checking out pictures of germ's girlfriends on thehun?
ok here is what I found... From California Bill's Chev Speed Manual Advance chart as follows: 1 deg. advance at 600 rpm 12 deg advance at 1200 rpm 20 deg advance at 2000 rpm 39.5 deg advance at 3450 rpm Vacuum Data: 7" HG of vacuum to start travel 16" HG vacuum should be 20 deg advance And from the Leo Santucci Inline Six Power Manual: For street use total advance should occur at 3000rpm which should be between 32-38 degrees. Cal Bill is referring to Chev 41-49 distributors but probably wouldn't be too different for 50's ?
Pure genie arse, good job VonTingler, good job DrJ for being an astute observer. My limited thinking means that the simplest of problems leave me befuddled. If I were a bicycle repairman I'd attempt to change flat tires without removing the rims off the frame. Anyways I'm printing this sucker because I'm an inline nutcase. I've got a working vacuum advance that I can use to copy for correct bracket length. You guys never fail to amaze me.
