Been a slow moving summer but starting to get unstuck! Late cams, bad parts, you name it, but weathering the storm!

This is the little 347 we did for a beauty of an early Bronco, will have 33-inch-tall tires, AOD, and a Sniper setup, so not your typical drag machine. AFR 185s, custom hyd roller with enough spread for vacuum and strong torque, Edelbrock Air Gap, Mahle pistons and S**T rods and crank.

Surprisingly fought the Sniper a bit on the dyno, but we'll get it...spun it up with a Holley and made a smooth 421 @ 5800, and 437 ft lbs @ 4500, was a little fat but the carb isn't going on this engine so we didn't chase it beyond 12.25:1. Leaner would have been meaner :) but table flat curves with HP within 3 HP from 5400-6000, it should be a runner in the EB!

Dual quad 427 FE power in a 340 lb package! Thanks Harry Heads & Auto Machine for giving it a spin!

Here is the next in line! My cherry picker moaned a little with the cast iron headers, crank and bell on it, but we got there :)

I'll get it inventoried and stripped down next week and see where we are going. However the plan right now is to stay 3.78 stroke, minimal bore with the ful CnC torque plate machining, upgraded remaining rotating assembly, tool still lifters, Nitride flat tappet, modern valve job and blueprinted heads.

The low riser should haul the mail when done!

BTW - don't try to call the number on the sign, that's the number to our family shop in Massachusetts my dad opened in the 70s. If someone answers, it's not us anymore :)

Steve Brown I thought you and the gang would like to see Jim Woods fine work. Gang, this beautiful dual point is prepped with a custom curve Jim Woods calls the Tasca Curve. He went through this distributor and it's a beauty. One more of the blueprinted pieces that makes it that much better.

We are lucky to have sharp FE guys doing distributors, Jim Woods on the east coast. Wes Adams on the west coast. This one is Jim's handiwork so a high five to him, always beautiful and right!

Keep your eye out for the next one...you have seen this block before, but it's freshly back from ArCut Performance Machine. This Dove alum block was CnC squared, torque plate honed, and it needed it. It's 4.255 bore x 3.98 stroke for 452 cubes, internally balanced and using Eagle rods and Ross pistons from its last iteration, with Dove medium risers, HS rockers, Trick Flow tunnel wedge, a pair of carbs from Air Fuel Spark, MSD ignition, and a custom nitrided solid flat tappet and tool still Trend lifters.

You can of course why I dislike Glyptal, over time it's not particularly happy and can chip, but what's there is on there solid

Last is a patient but stout 496. This one was not all affected by parts availability, but we did delay so I can plan all FEs on the dyno the same day.

This one is a 496, pump gas, RaceTec Pistons, K1 Technology rods, S**T Crankshafts steel crank, custom hydraulic roller, ported Trick Flow Specialties heads and ported medium riser dual quad. Carbs came from Air Fuel Spark, the only way to fly for these big FE and dual quads.

This one has plenty of cubes, cam, compression and carb, it should do well!

Continuing the theme of "things that should have been done already if parts were on time"... Here is a nice little 347 ready for the pump! I am whining a little but this was a perfect storm of all things, cam availability early in the year due to CnC machines going down and core availability

347 cid, about 10:1, custom hyd roller ground to our specs by Howards, Mahle pistons w/ 1/1/2mm ring pack, S**T Crankshafts 28 oz crank and rods, AFR 185 heads and an RPM Air Gap intake cleaned up by Dave Lasi. All block work done to tight specs by ArCut Performance Machine.

Owner added a Sniper and Dual sync, should be a stout performer in an early Bronco!

Been a wild July, family matters, unique parts issues, but finally getting there! Need to get some dyno time with Nick and Dale at Dale Meers Racing Engines and deliver a few big boys!

This one is a 511, race gas build, RaceTec Pistons, COMP Cams custom Bullock's hyd roller, S**T Crankshafts steel crank, Molnar rods. It's got ported TFS heads and a cleaned up Victor by Dave Lasi and a 950 Holley. This one should be a stout one!

Need to work out some dyno time and get 'er done!

Well, the boss said no more playing outside need to come in and prep for guests coming over for the 4th...the AFR 185-headed 347 is almost done. Just need to come up with plug wire routing and loom plan, a couple hoses, PCV and a few NPT plugs, drop the distributor and program the Sniper. It's a pretty little engine, should run very well too!

As I wait for parts to arrive for the remaining builds, I decided to jump back on my own. Genesis block you have seen, CnC square decked and align honed at 4.350 by ArCut Performance Machine with a 4.25 forged steel S**T Crankshafts internally balanced, K1 Tech 6.700 rods, RaceTec Pistons with metric Mahle ring set. Makes 505 cid.

I haven't really decided on the end results, but it will be an COMP Cams cam, ground to my specs, hyrdaulic roller, Morel lifters

TBD on heads, but may really lean into a set of Trick Flows for this one.

What do you do when you have 3 strokers going and waiting for parts? Start another of course. This is one for me, I think, I am pretty attached to my 489 FE but I have a few more tricks up my sleeve since I built it in 2006.

This is a Genesis block CnC machined by ArCut Performance Machine, 4.350 bore, S**T Crankshafts 4.25 stroke forged crank, we have a set of K1 Technologies rods, and RaceTec Pistons. 505 cubic inches.

This one is a little of a "build the plane in flight" kind of build. It'll get a custom hyd roller ground to my specs from COMP Cams, but who knows what that will be because I haven't locked in a head yet...either big K***z Stage 3, with port injected Victor EFI, or the same EFI with modified Trick Flows....I better decide soon! and I better decide if it's a Mustang engine or for my F100 while I am at it!
