Subject: Re: Season's over and time to rebuild. by rklessdriver on 2013/12/9 19:26:33 Wanted to show you guys some progress on my new engine. This is a brand new Howards Track Smart 3. 4340 Forged and 100% USA mfgr'd at Callis. I was able to get a great deal on this crank as my sales rep at CP sold me this crank for $680 on a "Cyber Monday" deal. This crank checked out and mic'd 100% perfect. 2.4480 on the mains and 2.0990 on the rods. Dead straight on every journal w/less than .0001 taper.

Here it is set up on the Vertical Mill getting ready to have the plenum cut open with a 1" end mill. [URL=http://s50.photobucket.com/user/rklessdriver/media/IMG_20131125_111237_zps022c4b2a.jpg.html]  [/URL]Here is a direct over head shot of the finished plenum after I cut it on the mill and radiused the runner entry's. [URL=http://s50.photobucket.com/user/rklessdriver/media/IMG_20131125_134642_zps62c2e5b8.jpg.html]  [/URL]Here is an angle shot looking down into the runners where you can see the crosssectional taper from the plenum roof to the runner roof. [URL=http://s50.photobucket.com/user/rklessdriver/media/IMG_20131125_134651_zps643fb700.jpg.html]  [/URL]BTW I removed .400 of material out of that plenum (.400 in all directions). All in all this work too about 6 hrs to do and I did not touch the runners (porting) past just thinning out the divider wings that extend into the plenum. If I get more time to go down therre and work before the intake goes on the engine I will fully port it.. if not it will go on as is. I'm sorry I didn't take more pics as I went along but this was never meant to be a "how to" thread anyway and operating equipment like this takes some level of concentration not ruin a $400 intake. I'll let you guys in on the parts and new engine combination. 434 cubic inches. 4.155" bore X 4" stroke. 5.850 Rod length. 13.1 SCR Dart Little M Sportsman block. Howards Track Smart 3 forged 4340 cranshaft. K1 Technologies billet steel 4340 rods. Diamond nitrous pistons, gas ported, 9cc dome. Perfect Circle Fire Power rings. .043, 1/16, 3/16 King HP series brgs. Titan Sportsman oil pump. Kevko box style drag racing oil pan. QFT Q Series 950 carburator Edelbrock 2892 Super Victor 2 intake manifold. Monty Smith Perf nitrous plate kit (380hp). Speier Racing Heads VFactor Profiler v2.70PF 250cc. You can see here, they are bad SOB's for 23* SBC. http://www.vfactorracingheads.com/vfactor-23ordm-sbc.html Jesel Shaft Mount Rocker Arms 1.7 ratio. Trend 3/8" .165 wall pushrods. Morel .903 roller lifters w/pressure fed axles. Comp Cams 6100 Belt Drive Mike Jones Camshaft custom ground to my specs. 332/348 @ .020 282/294 @ .050 .472/.465 lobe lift .802/.790 lift w/ 1.7 113 LSA 108 ICL GZ Motor Sports Super Pro Vacuum Pump. Stahl Headers 2" primary tubes into 3.5" collector. Schonfield 3.5" inlet/outlet bullet mufflers. Exhaust will be made by me from some 3.5" mandrel bends. At this point everything is set in stone (ordered and most is already here or being mfgr'd infact) except the rocker arms. The cyl head supplier may be able to get me a better deal on some rockers from LGM Engineering and they are 1.65 ratio which will lower the lift on the cam to .770ish but that really depends on how much money they save me over the Jesel's once my heads are ready. This motor should rock. The real hold back will be the 4150 carburator. We are still looking to make just over 700HP on motor. My Engine Analyzer shows a good bit more power than that but I don't want to get excited about a computer program.... Peak power should come in right at 7500 rpm. I hope you guys are learning something from all this. Will |
