I only have a backfiring problem when the engine is under a load or i put my foot in it to pass or something. But i can sit in park and rev it all day and not get a back fire from it.
the 350 has been in it since 2012 i've now developed the back firing issue, its always had sort of a rough idle anyway but never where it skips and picks up idle etc, My timing mark isnt in the right spot its been that way since 2012 when i did the cam and intake swap it was the only spot i...
Im gonna pick up a map sensor today on my way to work, I just replaced the vacuum lines going to the MAP and the EGR, I also unplugged the hose going from my master cylinder to the metal tube that comes out of my intake and the idle picked up like its supposed to and i pressed the brake with it...
Hi I havent been on in awhile, Ive got a 93 chevy with a 350, the mods done to the motor currently are an edelbrock 3702 cam and intake. I believe im having a timing or vacuum issue could possibly be fuel. If i try and put the timing at zero (computer should correct it 10 degrees when plugging...
I have no idea. Part of me is thinking he wants to just wants me to buy his custom chip, fuel pump and regulator. I mean ive read about swaps like this for sometime now and ive never herd of ppl needing more fuel. But I dont know...
Thats what I thought as well. But the tbi chips guys says that the heads need more fuel and without changing the pumo and regulator it will lean the motor out to much resulting in a motor loss.... I think im just gonna put them on and up the fuel pressure a bit.
I think thats what im going to do. It will still run fine with just a head swao first so i can slowly swap it out over time. Its basically the same build as someone else did there making about 280hp and almost 400ftlbs thats not to bad for a tbi plus there getting almost 20 mpgs.
The guy from tbi chips i saying i need a new fuel pump fule pressure regulator and a custom chip just to run these heads.. any truth to this? Everything else ive read says you can put them on and adjust the fuel pressure a little bit. If I have to go threw that much work and money I might as...
I just picked up a nearly brand new set of 062 vortec heads. Im gonna throw them on my 350. I know i need an intake but whats the deal with the egr? We dont need emmisions here in Maine so can i just disconnect it and call it good or will it cost me horsepower and fuel mileage? Also will my...
Change in plans... I just picked up a set of 062 Vortec heads with one summer of use for 100 bucks. Anyone Have any suggestions for an intake other then the vortec tbi intake? Id like to keep the tbi for now. Also will anything need to be changed with the tbi or can i bolt these heads right on?
