Drove it all over today with new coil worked great . Went to sleep got up for work drove to gas station about 2miles great went inside came out and started it back up missfire cyl 6. So looks like the inj is going bad. When it misfires if I give it a lil more throttle it clears up and check engine light goes out. Then it does it again a little later. I'm gona send injector for a rebuild but I need another stocker to test and make shure that's the issue . Code is missfire cyl 6. Not multiple cyl miss
Already bought the coil if it don't fix it ill have spare. If not I'm gona run a compression test I doubt it but may b bent pushrod. Don't seem like it thoug cause it runs fine cold then breaks up
Fuel pressure is 55psi pre start and 60 when running also same when misfire wich is why I'm rulling out inj I can feel it fire when its missing and the unburnt fuel is popping in the exhaust.
Went and got a new coil if this fails id like to try a inj. It shows num 6. Its intermitin but once it starts to act up it stays turn it off and let it cool and it starts and idles smooth then it starts again. Inj feels normal when its missing
Hey guys my camaro is showing a missfire on cyl 6 I replaced the plugs and wires but its still arround. Its intermitten me and steve drove it all was fine then 10 min later it won't run and hates life. I need a stock coil and injector to test and see what it it is. If u have these lying arround I need them
If u want a motor to last u treat a 12 sec motor same as a 8 sec one. Every machine step is nessisary for a long lasting engine. Anyone can build a motor that fails in 1000 miles. The tq plate hone is required for a round bore and longer piston - ring life. As well as a align hone for long lasting bearings. My 355 ran for 14 yrs so far been 11.78:1 with a 6-71 blower at 10psi. Tons of spray at 12.4:1 and its went 11.02 at 127 on motor alone. Still running in my s10 blazer and will get a 225 shot.
Here is the parts list in that motor. Trw forged piston very heavy eagle sir rods and stock gm. Forged crank. This motor built improperly with shitty machine work wouldent last very long. Reason I suggest the preped summit 383 block is simple. He's not looking for much power and it its way less money with all the work done.
Ok it seems a 6.5 is a 10.14 dunno if I can go that slow on 9psi I may have to slow the 60ft a lil. Can I run this class or is the rules against me again.
Its easily over 600 to properly bore tq plate hone deck and align hone a used block. U can buy the one at summit for right at 600. If u can't afford 600 for a completly preped block u proably shouldn't be considering a build. My 350 for splayed caps was well over 1200 for machine work. And my dart block has about 700 in machine work and its a 1500 dollar block.
