A couple of months ago I posted some issues I was having with my 340. I thought I had sorted them out by adjusting the valves. In all fairness the car tricked me. Because if I drive it, that's when it all goes to ****.
It will run beautifully for about 15 minutes. I take it on the road, and it starts loading up like it's getting too much fuel. The oil pressure drops. Idle drops. Power drops. I could surmise here everything I think could be wrong. Instead, I will tell you what's new and done to this p.o.s. motor.
New blue ignition box
New Moroso plug wires.
New Champion plugs
New intake gaskets
New resistor
.Stuff I did.
Trunk mount battery (hard to start when hot)
Pro Comp alluminum heads
.070 Cometic head gaskets (.024 deck height on pistons)
Solid roller cam (flat tappet Crane disintegrated)
Comp Cams extreme pressure valve springs
Pro Comp roller rockers (die grinder clearanced for springs)
Jegs electric Holley style fuel pump (Shitty Holley pumps leaked/ or just quit)
I have noticed that sometimes #1 exhaust, #4 & #6 exhaust stay cold even after car is warmed up.
Sometimes they operate normally. Fuel pressure reads 12.5 psi no matter the regulator or pump. I gave up on troubleshooting that crap. Car seems to not care most of the time anyways. I posted a video of it idling normally on youtube. I can provide a link if anyone cares. Wondering if when my hydraulic flat tappet cam died that caused damage? Cold idle I have 40 psi. Hot idle is 5 psi but climbs with rpm. I am at my wits end with this damn 340. Never spent so much money to have something run so horrible.
