this 4.1 engine, it was very famous here in brazil his name and chevrolet opala, and there are videos of him winning from new camaros ie the 6.2 and mustang gt 500 and others we thank you for making such an engine and at the time it was launched competed with Maverick V8 302 and dodge charger V8 318 and even today he makes the cars of this generation go to shame and thanks again for making this engine
The two wires that run to the coil,one is a run circuit with a resistor to cut it to 6 volt ,other is a start bypass so it has 12 volt to start. The way you wire it will use 6 volt to run , but hei is designed to run on 12 volt. Find a terminal on your fuse box labeled "ignition-fused" , and run a new wire from there to the distributor
@@38Sporty start from the ign post on the ignition switch and go directly to the distributor, the ignition is the only circuit that is nor protected by a fuse or a circuit breaker, you can fuse it but you should install a fuse of a much higher capacity than the requirement so this fuse will onbly blow in the case of a major shorting as in a crash to avoid fire hazard.
You may have found out by now, but those plastic fuel filters will let you down. I had one fail just last week, came home from town and later smelled gas in the garage. When I moved the filter it drained on my hand. Best stick with metal shell fuel filters, the extra cost will pay off.
Good Job Brother. This is a good post..and it allows for comment, hopefully constructive, to add to your very well explained conversion. If i may put my 2c. I love the 63. Many my age were spoiled with v8 sndrome. Imagine if no v8 was ever offered as an optional engine, the aftermarket would be overflowing with performance parts for this amazing engine. The inline 6 is awesome and dead reliable and obviously has a lot of potential. As Les Gallivan and probably others mentioned. One of the issues when running the old coil on 12 volts (im coming from the marine environment) is that the coil will overheat after about half an hour of running..and it will start to badly misfire. My guess is that with heat comes higher internal resistance. There have been some solutions to this..but basically it involves some kind of restance just before the coil.. On mercruisers, the wire itself has a higher resistance..and it is called "resistance wire." If that wire is INSTEAD, a regular copper wire, then a physical discrete resistor (discrete, as in separate. youve probably noticed them..they are usually rectancular blocks with a wire coming out each end)) is wired in series to the positive, cutting the voltage to around 6 to 8 volts and the overheating coil is solved. Otherwise, with neither the wire nor the discrete resistor, an internal resistor is built into some coils..and you would run Neither the resistance wire nor the external discrete resistor. What happens in boats..and im sure in cars too..is that when you try to start the engine with only 6 volts to the coil, the starter itself hogs the energy, drops the coil voltage..and you dont get the plugs to fire ..that is, the energy has to go thru all the windings of the starter before giving the coil its needed 6-8 volts, and the voltage there is drawn down too for the coil to "step up" the voltage needed to jump the plug gap. The solution to this is to use that second wire which is tapped to the start solenoid...before the starter.. which then runs to the + coil , bypassing the starter circuit. and is only energized to battery voltage as the key is switched to start. I'm pretty sure i got this right..but others smarter people will correct me if I got something wrong...or hopefully some one adds..
I often wonder if a full12 volts to the coil provides any added benefit...prior to the overheat...ie, hotter spark..say for a car that is drag raced only, as it will only be running for a few minutes at a time. And does that transfer to more power.. Which,, by the way begs the question. Does the HEI, besides adding reliability provide better power?
These were not very fast, but tough. I has a1954 in about 1958 drove it the 18 year old ( WIDE OPEN ) no problems. Sold to a older man he drove for 25 years.
Great video! ... is there a H.E.I. available for the 153ci inline 4 chevy II engine?.... And is there a difference in distributors between the 151 iron duke and the 153 chevy II inline four engine?
What kind of carburetor should I buy for mine I’m not sure parts are kinda tricky to come across for this engine or I may be looking in all the wrong places lol.
I'm looking at doing this set up on my 76 Apollo boat with the 250 straight six. Would like to see a video of it running and know how it all worked out for you.
yo man I got a 1972 nova inline 6 250 with a 350 tb tranny and I got the old points system and wanting to upgrade to something like this anyway u can make a video like a quick how to with demonstration I'm 19 and this is new to me helppppp
I got the just of it just need a better understanding like all the old wires what to do wit them or like how to clip the new wires in where they go what else u need other than JUST a new distributor ya dig brotha?
bade idea swaping from a external regulated alternator to internal regulator and I tell you why expecialy in winter time if that is a wariabel voltage regulator you can actualy buff up litel your baterry voltage meaning faster turning starter motor by bypassing you resistor to ignition coil you get a hoter spark you shuld by abel to turn over your car lot bether in winter time because fuel quality is shity lot of those older cars have lot trobel to turn over use lower viscositi oil and aditives for fuel posibly best solution to have fuel ore oil heaters perhaps even engine block heater you shuld consider to apply spay protection on all of your electric terminals moisture and heat protection that mostly kills the spark plug wires and posibly build a drain valve on your intake manifold gasoline engines dont like moisture at all if I were you I wuld shose that variabel externaly regulated alternator ore if you have a delco remy stille starter motor with a R starter selenoid terminal to bypass curent directly to ignition coil those older cars are a bitch to turn over
