I know there are some folks on here that are well versed in the Quad 4, my question is... what parts/pieces do you use to keep from running a serpentine belt? I've seen some killer pics of a Model A that is running one. Thanks.
The Quad 4 was not equipped with a V-belt option of any kind. I've not found a V-belt crank pulley to fit the crank yet. There is, however, a set of threaded holes in the end of the Quad's crank pulley to install bolts for a puller. Some 70s and 80s Chevy inline 6 water pumps had a third shive sandwiched between the fan and the double set normally found. That accessory pulley will fit into the front of the Quad's serpentine pulley. The center of the Chevy pulley would need to be releived to allow for the washer under the Quad's pulley bolt. A spacer will also need to be fabricated as the Chevy pulley is not deep enough. Then the pulley will need to be drilled for three screws. I am thinking about just cutting a V-groove in the serpentine drive for a drive belt. The Quad only needs to drive the alternator as the water pump is driven by the cam chain.
Mercruiser had the alternator in the harmonic balancer. If it's got a SBC snout you might go this route. Just don't run electric fans or EFI as only about 15 amps.
No SBC crank snout. The Quad unit is larger, so a guy could bore it. The keyway would need to be recut, though. A good machine shop should be able to do that. While we're getting complicated, a motorcycle stator could be mounted on the timing cover with a modified rotor mounted to a modified Quad crank pulley. It would look cool as hell.
Not to be a buzzkill but after woking on Quads over the years (auto tech), I don't really like 'em all that much. What's the attraction?
Great replacement for a worn out 4 banger. Small & lightweight; factory parts still available; 180-190 stock HP - more if you tweak it right; speed parts available; can be converted to a beautiful sidedraft carb arrangement (see above picture); cheap enough to be affordable at the salvage yard; easy to find; fantastic block steel and castings which will often still show the honing marks at well over 125,000 miles... need I go on? But perhaps this is most important: With that UGLY factory cam tower cover off the thing looks sooooooo much like an Offy it's enough to make a grown man cry. Especially if he knows what an Offy costs nowadays.
Excuse me. I thought the HAMB was about "traditional" hot rods, i.e. cars and motors '62 and older. I recall the Quad 4 originated sometime in the 1980's and therefore falls outside the "traditional" realm. If you use one doesn't that put you in with the "street rodder", billet, gold-chainer bunch that some here continue to rant about? I personally don't care because the Quad 4 has demonstrated real hot rod potential and people continue to use them in unique ways. Yes, they can be made to "look" like and Offy, but then its about looks and fau-realism. Like I said, I don't care. I personally wouldn't use one. If what you can afford is a Quad 4, then by all means use it and enjoy it. If I'm going to use a 4-banger then I'll opt for one of Henry's from the 1930's. More of a challenge to me. Everyone has to make choices.
Faux-realism??? Gimme an F-in' break!! - half of what goes on here falls under that heading. Alternators and electric fans, disc brakes, radial tires, air bag suspensions, dummy spots, blue dots and a blind adherence to the unwritten "flat black/red wheels/wide whites or cheater slicks/rolled cuffs & pomade" code of Rodding. None of this is genuine "roots" rodding but we all seem to accept it because it falls in the spirit of what we do. So what!!! Hell - half of real rodding is about at***ude and it's hard to project at***ude without looking the part. Alot of guys on here are the real deal, but we all can't be that way. Like you said, if it floats your boat then do it that way but if we're all gonna start ousting each other for "breaking the rules" then this board's gonna slim down and in a hurry. Chevy valve covers that look like a Hemi valve cover or an SBC diguised to look like a flathead - That's "faux-realism". Someone building a Quad4 and not hiding that fact is rodding, pure and simple even if you can't see it through the narrow mailbox slit of the chopped windshield of your mind. That's my 2cents and I'm stickin' to it. Anyone that don't like it can kiss my hairy white ***. Man, I gotta stop having so much cough syrup for dinner....
DAMN! I've only recieved one email notification so I had no idea anyone even saw this thread. Anyway...the reason I asked was WAY off topic, but I wasn't going to share that, but here goes... It seems I need a new serpentine belt tensioner on my daily and I've never had to deal with serpentine ******** before. I was hoping there was an easy way to swap in some other pulleys and have something I could trust that won't require removing all of the accessories to replace the damn tensioner. Oh well...I guess I'll just do it the way I'm supposed to. As for why people love them so much...they can take a hell of a beating and, in my case, I've got about 145,000 miles on it and still get almost 30 MPG. Slow as hell in my car but I bet this Model A will haul ***...anyone know whose this is?
I 99% sure that is the company car for Quads 4 Rods. They have a web site but I don't know the addy. I think if you type in the name and Google it, it will turn up
Damn Deyo, I thought you put together an A coupe for a minute.. When did you put a serpentine system on the Ford??
OK so with the sidedrafts, they look pretty cool. I guess I dislike them just a smidge less than I did before.
You got my point. I said that the Quad 4 has demonstrated real hot rod potential. Most of what "we" do is faux because there is no way we can duplicate what the old guys did in the past. We have to use what is available to us now. Nobody is talking about ousting anybody. We NEED all the input we can get. Hot rodders have always used what was available and what they could afford to build their cars and go fast. I have a very open mind. Thanks for expressing you 2cents. And thanks for correcting my mis-spelling of "faux-realism". My old fingers don't always work the way my mind tells them to. I'm glad that someone did get the info to Deyomatic.
