    Is Bradenton Fl. going to get closed down by subdivision?

    The track in Bradenton is way out in the country east of Bradenton. They were clearing land across the highway, north of the track when I was at the race in February. They're also taking Orange Groves at all over down there too for housing developments. Hopefully a few tracks will still be...

    Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

    You have to change a product 10% to not be infringing on a patent. However the knock offs don't even care about that. Tom

    Bad wreck in pro stock at Arizona

    If you lift the gas pedal or let go of the shifter handle on a Clutchless Liberty transmission it falls out of gear. Tom

    M1 Tunnel Ram Top Plenum Volume Reduction with Photos

    Got the plenum bead blasted today and tomorrow I should have the powder coating done. Need to get this one finished, so I can start another one for the Birdcatcher project. Tom

    Block off plates made and installed today covering the machined surfaces. There is no point in filling the inside with trash and dust. Hoping to get it bead blasted tomorrow and call it done. Tom

    452 heads on a 1965 Wedge ?

    Compression ratio is the volume of the cylinder sweep divided by the volume of the cylinder head. Nothing more to it. For what is worth I would never use a an .080" thick head gasket on an engine unless your running a Top Alcohol (Blown) class (which they do). Easiest way to figure compression...

    Will 383 pistons work in a 426 Wedge ?

    The math is: Bore x Bore, or Bore Squared 4.28" x 4.28" = 18.3184" x 4.375" stroke = 80.143" x 3.14159265359 (Pi) = 251.77666 x2 = 503.55" Or in the case of using a 4.50" stroke crankshaft it would be: Bore x Bore, or Bore Squared 4.28" x 4.28" = 18.3184" x 4.50" stroke = 82.4328" x...

    Will 383 pistons work in a 426 Wedge ?

    The cost of all big block kits are the same regardless of size. I posted the 541" kit as an example of what is included in my kits. I actually just looked into building a kit with a 4.28" bore, however the available pistons are not going to work with a 4.375" stroke. Below is what I've come...

    Will 383 pistons work in a 426 Wedge ?

    That's actually 503.55", not 505.55" Tom

    Will 383 pistons work in a 426 Wedge ?

    Then you still have to add the cost balancing, bearings, shipping, and sales tax. My kit is $3335.79 complete for any cubic inch size big block up to 541", and you get a Molnar Technologies crankshaft and connecting rods, ICON pistons, and King XP bearings. [FOR SALE] - 541" Molnar...

    M1 Tunnel Ram Top Plenum Volume Reduction with Photos

    The filing of the weld has finally been completed. I might have to do a small touch up here or there, and still have some sanding to do before it's ready for glass beading. Went ahead and removed the Mopar logo and the part number (something I always strip off of every intake I use) and...

    It's going to do some back to back testing when the time comes. I am also getting ready to cut another top right under the carb pads and weld a plate on that will accommodate an Enderle Birdcatcher. Tom

    M1 Tunnel Ram Top Plenum Volume Reduction with Photos

    Just about finished with only 4-3/4" on the end left to do out of the 41" all the way around, but I need to give my sore thumb a rest for at least a day before I can work on it again. Fortunately the end is a lot easier to do, so it will go quickly. Tom

    M1 Tunnel Ram Top Plenum Volume Reduction with Photos

    There's really not much to it. You just need an assortment of files (two rounds, a flat, and a triangle), some 50 & 80 grit sandpaper, and a glove to wear when sanding, so you don't wear your thumb out (It hurts). The blue handle file is a really coarse and cuts with ease. I find that I've used...

    M1 Tunnel Ram Top Plenum Volume Reduction with Photos

    I have about 3 hours worth of filing and sanding to be half way finished with blending the weld in at this point. Now that one side and one end is totally finished I am really happy with the progress so far. I'll do a little more sanding before I glass bead it and no one will ever know. Tom

    M1 Tunnel Ram Top Plenum Volume Reduction with Photos

    I've been really busy the last 5-weeks, but managed to get back on the plenum project a few days ago. Got the edges all beveled and the halves welded back together. Started filing the welds smooth and a little 50-grit sandpaper works wonders on aluminum. Once the filing and sanding is all done...

    I'm thinking I put too small a cam in my 360 Magnum...

    Regardless of whatever the actual lift you have on that cam I think the spring pressure is way to light for a 6500 rpm hydraulic flat tappet cam and especially from a single coil...

    M1 Tunnel Ram Top Plenum Volume Reduction with Photos

    There was no need to use a saw blade. The aluminum is only 3/16" of an inch thick on the sides of the plenum. The cutoff disc only removes .062" and in my opinion a whole lot safer than a toothed blade for my application. It cut super clean, took no time to do it, plus it was a very easy and...

    It's just a 1/16" thick, 4" cutoff disc from Harbor Freight. You can buy a package of 10 for $6.99 4 in. x 1/16 in. x 3/8 in. Metal Cut-off Wheels, 10-Pack The arbor is a fine thread 3/8" bolt that I cut the head off of and two washers/ two nuts. I only ended up using one disc to do all the...

    M1 Tunnel Ram Top Plenum Volume Reduction with Photos

    I did a 65 cubic inch plenum volume reduction on a Mopar M1 Tunnel Ram top to better suit my intended RPM range usage. I think it turned out very well. A little beveling, welding, smoothing, and it will be ready to go. Tom

    What Fuel Pump Are You Carbureted E85 Guys Using???

    I've been a long time MagnaFuel customer having bought a ProStar 500 in 1998 and never having any issues with it. Plus I like the looks of them better than Aeromotive. I am now 99% sure I'll be buying the MagnaFuel Quickstar 300 for this project. Maybe a little more pump than I need, but should...

    1350 dana 60 - 8.75 pinion yoke ?

    Peace of mind is sometimes worth more than the additional cost you had to layout. Increases in safety to you, your car, and others that are in the vicinity of your car are priceless. Tom

    1350 dana 60 - 8.75 pinion yoke ?

    Yes, but only because I tossed a driveshaft out at 115mph years ago so now I am super anal about heavy duty parts in the driveline. The Strange $12 U-bolt kit will never let you down. The OEM style straps weren't the cause of losing the driveshaft, as they were still bolted to the yoke, but I...

    1350 dana 60 - 8.75 pinion yoke ?

    Not that you'll probably need it, but the Strange has a machined area where you can clamp/ bolt Pick-Up Collars on it so you can monitor driveshaft speed. The others have no provision for this. Tom
