Pretty good is correct. LSA at 110° is just slightly wide. I would order the cam with 108° LSA. If using LA heads with shaft rockers, I would get 1.6 ratio roller rockers for the intakes. 1.5 roller for the exhaust. I would seriously consider the Chev LS valves that are 1.9" I and 1.55 E. To do...

On an otherwise stock spec engine, definately so. An acceptable step up would be 214°/224° @ 0.050". With that another upgrade would be rockers with .1 more ratio, especially on the intake. An appropriate 4V manifold with 650 carb and headers to make it all come together. Exhaust a bit over 220°...

Depends on the person. IMHO that is getting a bit more duration than I would want for a street 318. To me 220° @ 0.050" is about the max for a street 318. As you are aware a larger displacement tollerates or likes more duration and lift. Personal preference and expectations vary widely.

Your Magnum heads have quench, correct? With 9.2:1 CR, I would choose a modern cam profile and run 87 fuel. I do not expect you to have a problem with that. As recommended, talk to Jones Cams and Oregon Cams. Have your engine information to send them. The more infirmation you fill in the better...

Maybe, just maybe you should watch some David Vizard and Unity Motorsports Garage videos. There are a bunch of others also that speak to ported or manifold vacuum. The short speech; manifold vacuum with an adjustable vacuum advance so you can dial it in.

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

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...

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.

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...

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...

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.

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...

Go with a TKX 5 spd.

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.

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...

Cast where ever. Once the war will pootlerstan is over I would pick Ukraine, an ally country. Machine in America.

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...

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...

Communist!

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...

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...

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...

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...

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

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.

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...

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.

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.

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...
