221-302 are 8.2", not 9.2" Tom

Now might be the time to buy a single stage belt driven oil pump. Eliminates a lot of issues. Tom

OEM 351 Windsor block is 9.500" That is incorrect. OEM 351 Cleveland block has a 9.200" deck height OEM 351 Windsor bock has a 9.500" deck height However the hot setup is buying an aftermarket Windsor block with the 9.20" deck height and 302 mains if you want to race. Tom

Everytime an NHRA Pro Stock engine had the deck height lowered a .100" they picked up 15 HP. Now Pro Stock deck heights are down to as low as 8.600" It's not a secret that lower deck heights allow for more horsepower to be made. Tom

A normally aspirated engine will always prefer a bigger bore to allow larger valves to move more air. Higher rpm racing engine you would want way over square 4.375" or 3.91" stroke. Heads up you're going to need it still pulling at 7500 rpms without running out of head. Depending on the level...

I use Lucas or Amsoil Red Grease, so they don't require checking but twice a year and rarely require more than one or two pumps if that. Tom

I absolutely wouldn't spend the time and money to upgrade them. Even if you gained 10 HP and I really doubt that. You'll end up losing TQ in the RPM range. FYI: I have 1-7/8" headers on a very well built 499 RB and that's all the header that engine needs. Tom

In Milan you can buy gas at the track. Dirty Harry's Performance Shop - Milan Dragway Tom

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 out all over down there too for housing developments. Hopefully a few tracks will still be...

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

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

Indianapolis Raceway Park was supposed to open this weekend and the cold and rain did it in until next weekend. Tom

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

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...

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...

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...

That's actually 503.55", not 505.55" Tom

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...

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

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

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...

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

65 cubic inches Tom

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...

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...

It's been a long winter Tom

Stopped at Alkydigger in Nashville, TN today and bought an Enderle Birdcatcher setup. Took a few photos around their candy store showroom to share with you guys. Tom

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...
