Posted July 25, 2018<\/span>:<\/strong><\/p>\n

On July 7th 2018<\/a>, we damaged the 350 in the ’57. We cracked two combustion chambers in our old Dart<\/em>\u00a0Sportsman<\/em>\u00a0fully ported cast-iron heads and destroyed two piston<\/strong>\u00a0skirts. Running a dial indicator up and down the bores show a .0015″ deflection and the deck has warped in only 30 runs. The old -010 block just won’t take the higher horsepower we were making.\u00a0We’re done with stock blocks at our horsepower levels!<\/span>\u00a0We’ve had great luck with the Dart Little-M<\/em> in the Chevelle.<\/strong><\/p>\n

So for 2019 we are working with Dale Green of DG Machine<\/em><\/a> to build a new 3.48″ stroke small-block using the Brodix\u00a0STS T1 215 CNC<\/em> ported aluminum heads with 64 cc combustion chambers and 2.080″ intake, 1.600″ exhaust valves. To accommodate the wider chambers based on a 400 SBC bore, we’ll be using a 4.125 based bore Dart Little-M<\/em> block so we don’t shroud the valves with the conventional 350 4.00″ bore. We plan on using GRP<\/em>\u00a0billet aluminum rods and a Jesel<\/em> shaft rocker system to match with the 60\/40 valve spacing on the new heads along with Isky<\/em> roller lifters.<\/strong><\/p>\n

We’re looking at somewhere near 750 hp and a torque increase of approximately 40 ft. lbs from our current 350 with the improved airflow numbers, so we’ll need to be careful with the clutch and launch RPM to be kind to our old Doug-Nash<\/em> 5-speed. IF we build this motor w<\/strong>e’ll need to also\u00a0 update the old drum front brakes to Wilwood<\/em> discs to handle the higher MPH we’re expecting.\u00a0<\/strong><\/p>\n

We’ll provide far more details as the build progresses. We are only in the research stage at this time! – Roger<\/em><\/strong><\/p>\n

After speaking with Dale Green on specifics, Pam and I are moving forward on the new build which will feature Wiseco\u00a0<\/em>custom pistons with heavy-duty pins, .043\/.043\/3mm ring pack, GRP<\/em> aluminum rods, a Dart Little-M<\/em> block, Scat<\/em> crank, etc for 2019. We’ll also be purchasing new Brodix<\/em> 215 CNC-ported heads for the new engine from DG Machine<\/em> and will be using Jesel<\/em> shaft rockers.<\/strong><\/p>\n

Dale Green now has the new block and crank, waiting on custom Wiseco\u00a0<\/i>pistons and GRP<\/em> aluminum rods to begin machine work.<\/strong><\/p>\n

October 5, 2018<\/span>:<\/strong><\/span><\/p>\n

The new rods and pistons have arrived and DG Machine<\/em> is starting to machine the new Dart block. Below are a few pictures of the GRP<\/em> rods and Wiseco<\/em>\u00a0gas ported pistons with the .043\/.043\/3mm ring package and I’ve ordered the Jesel<\/em> shaft rockers for the new heads:<\/strong><\/p>\n

DG Machine<\/em> is beginning to file-fit the rings for the final assembly of the short-block.<\/strong><\/p>\n

November 8, 2018<\/span>:<\/strong><\/span><\/p>\n

Dale Green called tonight, short block and heads are done, he just needs to get the proper Cometic head gaskets and a few odds & ends and we can pick it all up! My thanks to Dale & Lane for all their hard work on this project! – Roger<\/em><\/strong><\/p>\n

November 19, 2018<\/span>:<\/strong><\/span><\/p>\n

Dale Green called today, all the extra parts we ordered thru DG Machine<\/em> are now in and ready for pickup after Thanksgiving! Dale calculated the finished compression ratio at 13.68:1, right on the botton! – Roger<\/em><\/strong><\/p>\n

November 23, 2018<\/span>:<\/strong><\/span><\/p>\n

Chris and I picked up the assembled short-block, new Brodix heads, Isky Red-Zone rollers, etc. from DG Machine<\/em> this morning and we’re delighted with the clearances in the new motor. I’ve added pictures to our photo gallery below. My thanks to Dale Green & Lane Cavar for all their work on this project! – Roger<\/em><\/strong><\/p>\n

Piston to wall clearance (coated skirts): .0040″<\/strong><\/p>\n

Main bearing clearance: .0028″<\/strong><\/p>\n

Rod bearing clearance: .0030″<\/strong><\/p>\n

Rod side clearance: .020″<\/strong><\/p>\n

Crankshaft thrust clearance: .005″<\/strong><\/p>\n

Camshaft thrust clearance: .006″<\/strong><\/p>\n

Deck clearance: .011″<\/strong><\/p>\n

Quench with .040″ Cometic head gaskets: .051″<\/strong><\/p>\n

Lifter body clearance: .0025″<\/strong><\/p>\n

November 24, 2018<\/span>:<\/strong><\/span><\/p>\n

Today Chris and I set the valve timing, used modeling clay to check for valve-to-piston-clearance and dome-to-combustion chamber clearance after mocking up the Jesel<\/em> shaft rockers and determining what pushrod length we need for the new motor. We also checked the intake match porting to the new heads and they are on the money which makes life easier! And we checked the valve spring installed height on the new heads and both closed and open spring pressures which are looking good!<\/strong><\/p>\n

November 26, 2018<\/span>:<\/strong><\/span><\/p>\n

Today we got the old oil pan on the new block. Chris had to use his bench sander to remove a slight amount of material from the pan rail sides of the three center main caps – like we’ve had to do in the past – to clear the integral scraper inside the Moroso<\/em>\u00a0kick-out pan. Of course we did NOT<\/span> remove any material in the saddle area! We installed the Isky Red-Zone<\/em> Maximum Endurance<\/em> lifters and primed the oiling system making sure we have oil to the pushrods before we install the heads!<\/strong><\/p>\n

November 27, 2018<\/span>:<\/span><\/strong><\/p>\n

Today we got the new Brodix<\/em> heads with Cometic<\/em> head gaskets on the motor and installed the Jesel<\/em> stands for their shaft rockers. We also leaked down the new engine and are pleased with the results. Now, just waiting on new Smith Bros.<\/em>\u00a07.750″ pushrods as this build is nearing completion!<\/strong><\/p>\n

December 2, 2018<\/span>:<\/span><\/strong><\/p>\n

Smith Bros<\/em>. .116 wall pushrods arrived, and the Jesel<\/em> shaft rockers are now fully installed with all the recommended lube. Next we’ll fully prime the oiling system with the rockers on before installing the intake manifold. Good progress on the new 372 for our ’57!<\/strong><\/p>\n

Chris came over this afternoon and he primed the oiling system while I manually cranked the motor over and we have oiling at the Jesel<\/em> rocker arms, so next is installing the intake manifold and this build will be complete! We’re looking forward to the 2019 season!<\/strong><\/p>\n

December 5, 2018<\/span>:<\/span><\/strong><\/p>\n

Today I installed the intake manifold, distributor & valve covers. All that is left is indexing a set of plugs, installing the front motor plate and header plates and it is ready to go back in the ’57 !!<\/strong><\/p>\n

December 18, 2018<\/span>:<\/span><\/strong><\/p>\n

I got the header plates modified today for the new exhaust ports and installed and indexed the new sparkplugs! So, this new bullet is ready to go back in the ’57 in the new year!<\/strong><\/p>\n

Again, my thanks to Dale Green, Lane Austin Cavar for all their work on the shortblock and to Chris Young\u00a0for helping me assemble the rest of the new motor! And to Pam Young\u00a0for all her love, support and remarking the old harmonic balancer so I can read it with her steady hand!<\/strong><\/p>\n

Before the car goes to the track, we’ll be updating to Wilwood<\/em> front disc brakes thanks to Chris so we can get the old buggy stopped! We’ll have more on that upgrade when we begin the installation. – Roger<\/em><\/strong><\/p>\n

February 21, 2019<\/span>:<\/span>\u00a0<\/strong><\/p>\n

We’ve been waiting for the weather to cooperate to get the new motor in the ’57. Unseasonable low temps, rain & snow have delayed getting the car put back together. – Roger<\/em><\/strong><\/p>\n

March 2, 2019<\/span>:<\/span><\/strong><\/p>\n

Today Chris got the engine compartment painted after the mess we had from the cracked head. As soon as the weather warms we can install the new bullet! – Roger<\/em><\/strong><\/p>\n

March 16, 17, 2019<\/span>:<\/span><\/strong><\/p>\n

On Saturday, Chris, Paul and myself got the new engine in the car along with the clutch and transmission, radiator, etc. Pam kept us well fed and kept the coffee coming!!<\/strong><\/p>\n

Sunday morning we got the headers installed on the car, primed the oil system and fired the new motor off. We set the ignition timing, had excellent oil pressure and it was oiling well on the top-end and ran it through the gears. I’ll recheck the valve lash prior to our first outing. My sincere thanks to the family for all their hard work and support getting the old buggy back together! It was great hearing it come to life again! – Roger\u00a0<\/em><\/strong><\/p>\n
