340lc and 440 lc restore and rebuild

[red19lite]

motorhead ive got a long way to go before i get that light bottom end in something ive got three sleds in parts, 76 440 nitro, 77 44o nitro 76 magnum 250 and lot of parts, want to build a custom with this crank and the flat slide carbs heres a picture of my 76 crank being stuffed with high temp epoxy, i could have used a extra hand mixing and handling the epoxy

[red19lite]

forgot th picture hers the crank webs

[red19lite]

here the center webs

[red19lite]

sorry guys i got a lot more pictures , but i have hughes net and something changed on my internet explorer and i cant get any picture out.

[red19lite]

i hope the pictures work now center webs

[red19lite]

here the crank webs being pressed together internet explorer updated t 8.0 then hughes net doesnt support it had a hard time loading picture looks like we got it know had to go back to 7.0 these damm computers are making problems all the time

[red19lite]

crank all done got run out down to .002

[red19lite]

crank installed with new seal and three bond sealer and reshimmed

[red19lite]

ready to bore clyinders that were trued and squared earlier, they are set up on bottom to get true 90 degree bore alinement, the clyinders wear most at the intake and ex-ports ,these will have to go +.020 thats only +010 from each side be aware of this if you buy oversize pistons +.010 is not much only +.010 from each side i should have available pistons for 77-78 440 soon up to +080, 76 piston in about a month for resale

another picture of cylinder on boring bar all but .002 will be machined out then the ports will be chamfered, then they go to the hone for the final sizing

bottom of cylinders being trued up

clyinder head resurfaced ,any body know where to get new expansion plugs for 76 nitro heads? the thermosat side was also re surfaced, if i can find the expansion plug i will have to make one drill out for pipe plug or something any body else do something different with this problem? , the oringnal plug was a rubber coated expansion cup metric sized

[red19lite]

here water manifold, reeds with boyseens , and other parts surfaced and cleaned up

[red19lite]

here the engine for my 76 nitro about half done, new crank bearings,seals, rebuilt fuel pump, flywheel and stator and recoil installed , new pump belt,cases blasted and painted with duplicoler engine paint, this engine will go in my trail beater

Hi from Motorheadman
That is looking real nice thanks for all the pictures. Did you do any porting work or mods to the exhaust system? Also I was curious if you CC,d the heads or do you take a squish measurement off the piston domes.

no porting on this one its just a trail beater i will cc some 76 and 77 heads a post it later, i got three project engines going, need to get this one up and going we just got 2 ft of snow about the only thing i going to do on the exhaust is dump the cans for some different silincers so the pipes are easeir to get on and off, still waiting on oversize pistons, ive got a lot more to share later kevin

[red19lite]

fixed the expansion plug todat drilled and tap to 3/4 npt

[red19lite]

here the set up cound not fine replacement expansion plugs any where, i going to use a alluminum internal socket pipe plug instead, finally that problem solved

[red19lite]

made a torque plate out of a badly damaged head to be used on final clyinder honing after boring

[red19lite]

here my bottom crankcase half that i use to mill match clyinders tops,i modified it for lower torque plate for final honing, it had to be bored thu to have hone clearance , i should be able to get some great round clyinders under real torque loaded stituation
