    348 stroker in mag

    Some issues with the CHP issue I ran out and grabbed the CHP mag 'cause I got two 348's and I'm hot to build me a stroker motor. I was pleased to read there is someone in So Cal that knows something about W-Motors, since a lot of you guys seem to be in the Mid-west. I gotta agree with...

    Starter ?

    Beware Beware of the mini starters that do not have a support on the snout of the pinion shaft for the starter gear. I have found they tend to wear out pretty quick in hi-torque applications. If you go to a good starter/generator shop and tell them what you want, they can build it for you...

    Dual quad tuning

    Today was a bright, clear, cloudless day her so I got the 39 out and warmed her up real good, then set about tinkering and tweeking per you guys suggestions. Yeah, I was way behind on the ignition timing. Bumped up to 12 degrees initial, can't tell where I am at all in, timing mark seems to...

    Dual quad setup

    No hot start MRHP - no I don't have a hot start problem. Once I fianlly get it started it will start right up all day long. I'm running shorty block hugger headers, I have the crossover blocked off at the heads, I'm using a Holley electric fuel pump regulated down to 5 PSI, I have phenolic...

    Dual quad setup

    Btw That 32 with a 409 is looking good. I made good use of the Offy rocker covers I purchased from you last year.

    Dual quad setup

    More info Mac, no, I only have a choke of the rear (primary) carb. The choke plate is removed from the secondary carb. My hard-start problem sounds the same as yours. This is a weekend only car. I think I can set up my progressive linkage to run both carbs at once. I'll give that a try...

    Dual quad setup

    I running dual Edelbrock 550 square bore quads with progressive linkage on an Offenhouser mainfold on my 348 with an Isky 268/268 hydralic cam. My question is in regards to setting up the carbs. Most advise to shut down the idle circuits on the front carb, but I have mine set up with the idle...

    Is This edelbrock 6x2 intake wrong for my 409?

    No dividers I have seen this manifold before and the whole area below the carbs is open, like a tunnel ram. The primary difference between this mainfold and a tunnel ram is this mainfold has no long runners to create any port velocity. The concept was to allow any cylinder to draw from all 6...

    Stroker 348?

    Dyno results This sounds great guys. I hope you will all post the dyno results with spec sheets for each of your engines. This is the kind of information you just can't get from any other source. If we could have 2 or 3 different engines of different bore / stroke combos with all the...

    New Edelbrock pics...

    Grand national Roadster Show I was just at the GNRS in Pomona this past weekend. I spoke to a guy at the Edelbrock display in the vendors area. He said they were expecting a release of the heads on March 15, 2008. Wouldn't give me a price...said he didn't know what they price point would be...

    Stroker 348?

    With all the big-inch 409's around, I am wondering if anyone has gone to the trouble to build a stroked 348. I realize the bore is a .25 smaller, but will the 4" crank from the 454 fit? With a .60 overbore, this should give something in the range of 450 cubes. Add the new Edelbrock heads and...

    mini alternator mounted down low

    Driver's side vs. Passenger side Yoknow, I had a little trouble with the steering shaft for the Mustang II rack also. Tried to switch to the passenger side, but it just didn't work as good with the mount. Yeah, I don't have a lot of room to get the belt tight, but it works, and thats what...

    Need help with Bellhousing numbers

    Get a scattershield I used a Lakewood scattershield for a big block on my 39 with a staggered block mount starter. bolts right up and looks pretty slick. I don't think my 348 has the beans to blow the crap out of the clutch and flywheel, but I like having the extra insurance and the...
