yes the portion that threads into the combustion chamber is the same length as the delco,the overall might be different however.I bought a street rod and it has a Chevy 350 30over pistons and a 350hp cam . It has r44t spark plugs in it. Can I use the e3-42 in it. They seem to be longer than the 44. Thanks Robert
So the electrode is farther into the head? It won’t hit the piston?? Thanksyes the portion that threads into the combustion chamber is the same length as the delco,the overall might be different however.
Is the threaded part longer between the two?So the electrode is farther into the head? It won’t hit the piston?? Thanks
No same size but the electrode sticks out longer into the headIs the threaded part longer between the two?
Thanks for all the good info. They said at e3 . Com they would work. Put them everything is good!! Havnt drove the car yet. ThanksWhen shopping for spark plugs what you want to look at is the reach dimension that determines how far it goes into the combustion chamber. Your 44's and the ones are looking to buy are the same.
