    Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

    Chinese companies will produce to the quality standard you demand or allow.

    Cheap 318 performance mods.

    Look into David Vizard's videos. Dual pattern does compensate for a less than beneficial exhaust system. OEM iron manifolds definately fall into the less than beneficial category in most cases. There have been a few pretty good ones for performance engines. Cast manifolds for the OEM are...

    Cheap 318 performance mods.

    OK. I can accept that. Just my experience and the technology has come a long way. Just my opinion is to build a torquey engine for the street first, keeping in mind the possibility of installing gears or/and converter later.

    Cheap 318 performance mods.

    My experience of pulling wrenches for 30 years points not to the Magnum having less cylinder wear than the LA engines because of design. All manufacturers engines took a substantial leap in engine life with the introduction of EFI. The throttle body systems improved fuel atomization so wear was...

    How far in the hole 318 pistons

    There could be a number of other factors involved that the factories could have used beside fudging the numbers. Camshaft profiles could be one. Lower intake lift but longer duration is one I found in the TRW cam catalogue. This applied to Mopar, Chev and Ford bread and butter engines of the...

    How far in the hole 318 pistons

    Very true Rusty. The open chamber heads did have more tendency to detonation. Other factors in the emissions systems of the day caused drivability issues. The eengineers were having fits trying to figure out how to lower all the pollutants and be able to have reasonable drivability. The VW...

    Yup. More than one way to skin the cat. Now to figure how to get at the left dishonourable prime peckerhead of Canada, daesh dustbin turdo so we can skin his sorry arse.

    How far in the hole 318 pistons

    By 72 emissions were kicking in and the CRs dropped into the outhouse basement. Between either dish pistons or 0.040" to 0.100" down and combined with open chamber heads the combustion was terrible and prone to detonation. Best bet would be figure new pistons to zero deck it with modern rings...

    Do I wait for the 5 speed?

    Go with a TKX 5 spd.

    Small Blocks

    How so on the rod to stroke ratio. You take up the difference of say 0.5" in the piston compression height. Stroke and rods stay the same.

    Headlight Relay Kits

    No worries on the lights getting hot enough to damage the plastic grill. I would check the wire gauge to the relay power (30) and the out to the lights (87). Should be 12ga and then the bulb ground should be 10ga. This will ensure good bright lights that are trouble free. The ground is part of...

    Cheap 318 performance mods.

    Calhoun, first is what is your intended end use? Do you mainly want a Cars and Coffee cruser or something with more zip. When building any project you need to have an honest conversation with yourself. Self, what have we got to start with and where do we want to get to for a completed project...

    Cheap 318 performance mods.

    Ya Ya. Hi stall is OK for more of a track car. With the stated 3.23 gears a 3500 stall converter will always be "slipping" creating heat and poor fuel economy. With a short duration cam, a slight bump in compression, a 4 barrel intake of 2 plane design and headers, a lot of stall is not required...

    Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

    When you purchase Chinesium Yak turds ****, you are selling your soul to the communist Chinese guvment. Choose your poison wisely. As for me, I try to avoid that. Look at Europe and how dependant they were on fuhrer shorty the shirtless for gas to heat their homes. Since they figured out they...

    Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

    My problem with Chinesium **** is it comes from a pretty much unfriendly adversary country. These companies are affiliated with the CCP guvment, so their profits prop up and aid Xi Wanshortdong and his aspirations to take the US of A down. If you want to set up a business in China you put up the...

    Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

    Making incremental improvements is what got us where we are today. Looking at some product and thinking I could improve this if I just changed x is what builds a new product and probably patent(s). What Speedmaster did was an unashamed and blatant copy, leaving the logo in place. To do R&D to...

    Cylinder wall weld??

    IMHO, that is definately not JB nor brass. Appearance is like stainless so it is nickel rod. You need to be careful.with cast iron as it can crack at the edge of the weld as it cools. You must take steps to stress relieve the area. I could see preheating the area and using a tig with a nickel...

    Cylinder wall weld??

    Looks like high nickel rod. Frequently used for cast iron repair.

    I think i broke rear main bearing

    Definately not. The pump body must be flat and tight on the main cap to hold it in place. Remember the output that then goes to the oil filter passes through there. If it is not tight it will leak like a rabid babboon with diharea.

    Headlight Relay Kits

    I would use 12ga to each power to the bulb filaments and 10ga ground. You will have no voltage drop and lights as bright as possible. The OEMs have to take profitability into consideration so they use as small wires as possible. Smaller wire is less Cu and plastic for insulation. If they save...

    Headlight Relay Kits

    That is why it is good practice to shut the compressor off at night and drain any water out. You probably do not want the compressor running all night or weekend.

    Headlight Relay Kits

    Power wire supplying power to the 30 terminals should be 10ga or 8ga so no voltage drop. You can use one relay to turn power on for the low beam lights. Two relays can switch from lo to hi or just to turn the hi beams on.

    Headlight Relay Kits

    I do like fuses coming from the power supply to the relays, just in case. Local Ford dealer had a shop fire a few weekends ago. Service department is totally shut down. Word is they had a truck on the hoist with a wiring issue bad enough they could smell hot wiring. Now how any responsible...

    How to achieve this stance please?

    Some young fellas in a small town in Saskatchewan, Canada were into street racing Mopars. One had a Duster 340 with 4 spd trans. He got ahold of a narrowed rear axle for it. The car sat level like off the showroom floor. Another young fella in a small city an hour away had a Charger 440 with a...

    273 Commando - UTG

    IMHO there is nothing wrong with the 273 for the time period. Ford had the 260 and 289 and Chev had bored the 265 to 283. All good engines that got further displacement increases. And they were reliable. The SBM was generally good for 150,000 miles while the Ford and Chev were usually pretty...

    I think i broke rear main bearing

    Really the only proper way would be to find another block. You could look for a rear main cap from a scrap block. That requires engine removal and complete disassembly to enable align honing the mains for proper alignment of the new main cap. Taking the cap to a machine or welding shop to be...

    Headlight Relay Kits

    Lots of those are chinese crap. Easy enough to make your own with Bosch relays and American or European made fuse folders. The less Chinesium we use the better. China is a hostile adversary, so we do not want to support it if possible. Watch the video about Summit removing all Speedmaster products.

    Headlight Relay Kits

    Dash lights probably due to less current draw so less voltage drop through the switch. I doubt the tail light difference would be noticable. To really brighten the tail lights you would need to run a fused 10ga wire to the trunk. Three 30A relays. One for the tail lights and one each for left...
