So I got a tired early 70s 350 in my FJ40 that I want to swap out for a fuel injected 350. Optimally I'd like to go port injected (O2 sensors, etc) and something I can put new in a long block configuration. If it matters, it has Vortec heads with Corvette exhaust manifolds right now.
What is...
less (thiner) air = more (richer) fuel mixture = fouled plugs. I don't think hotter plugs will help. My motorcycle with a carb I need to have adjusted for high altitude driving.
I would check to make sure that you are not already running rich at the altitude you drive at often. Or perhaps...
If you have problems with temps on the highway you have a cooling capacity problem. The engine is running harder on the highway and needs more cooling but the radiator sounds like it can't handle the job.
Accel wires
Ok, this is what it looks like now (sorry for the bad picture) and from the look of these ceramic boots I don't think I'll have a problem anymore.
I guess the combination of ram horns and vortec heads didn't exist so maybe I'll lay off Edelbrock :-)
Anyways, thanks for the info. Those Accel wires are PRICY but if it gets the job done then I'll givem a try.
Well I don't think that the routing of the wires has anything to do with this problem because it is the actual boot that is getting burned out. Anyways I'm running the wires on the front two cylenders down then around the from of the head along the top of the intake manafold. The back two...
So I built up a 350 with Edelbrock E-Tech Aluminum heads and Corvette 2.5" Ram Horn exhaust manafolds and every time I get on the freeway (when the engine is really working) I burn through one of my spark plug wire boots that is near the exhaust manafold. The engine starts misfiring on the...
Thanks for the info. I really think it is a crankcase pressure problem because it doesn't just drip out of the valve cover screw holes but flows when the RPMs get high.
I had a new 350 engine built up with Edelbrock Aluminum heads and a high pressure oil pump. I mash the gas yesterday and when I got to about 450RPM a big cloud of smoke comes into the cabin. That kinda freaked me out.
So today I start slowly increasing engine RPM while under the hood and sure...
If the engine runs hot when on the freeway it is usually a radiator capasity problem. If the problem is a low speeds, it is usually the fan. Running without a thermostat makes the water move so fast it doesn't have time to cool in the radiator (at least that is the theory I've heard)
If you...
