    Any cb’s that would fit in the radio slot?

    My truck came stock without a radio, and I’m doing fine with Bluetooth. But now I want a cb, and don’t want to mount it under so my knees don’t bump it, and I’d rather not roof mount it because the headliners pretty nice. But since I already don’t have a radio, are there any cb’s that would fit...

    4-6 speed, hydraulic operated shift, automatic transmissions that work with first gen 350

    My trucks got a th350 right now but in the future I want to swap the transmission and do a 4wd swap. What would be a good transmission to swap in it for better gas mileage and towing etc? Also paired with a good transfer case. Needs to be heavy duty for off road use. I’ve been thinking a 700r4...

    Idling high and can’t get it lower

    My sbc 350 is idling high. I have the idle screw backed out all the way and have pulled the throttle back and it is still high. I was thinking it might be the choke because it’s not closing fully, it’s the electronic one, and someone I know told me it might be the thermostat but I wanna check...

    How much oil pressure is to much for a stock 350

    I got a stock 350 4 barrel that I just replaced the oil pump on, and I haven’t had it idle for more than 5 minutes at a time, mainly cause I’m working on it in the middle of the night. But whenever it is idling it starts up great, then goes up to 55-60 psi. And if you rev it it goes past 60...

    sbc 350 oil pressure from 60 to 5

    Backstory: I started it up fine and it was idling at 45 psi, which has been pretty normal lately. I figured it was just cause its been a little colder. As i got offroad it went down to about 30 psi. Then i went offroad and i noticed it didnt sound like it was firing right, but i was already up...

    Question on battery/starter

    Backstory: Keep in mind the battery is a week old. My truck always starts easy, normally within a few seconds with 1 pump of the pedal. The other day it started just the same, even with it being below freezing. I drive about 5 minutes then it was parked for ~2 hours and when I tried starting it...

    Did speakers come default or was that an added option

    My truck is stock with no radio, it’s got a plastic cover in place of the radio. But it has a dash with holes right in the center that looks like a speaker would go there. Did some digging and some are saying all had speakers, some saying it was an option. Could just be that all dashes were...
