    Blown head gasket 350

    I am looking at purchasing a 1998 K2500 with a vortec 350. It has less than 100k miles on it and the owner stated that he had to get a head gasket replaced on it. What could have caused this head gasket issue? Could it possibly be a tirepatch fix for a bigger problem?

    HEI wiring, electronic choke wiring and carb linkage for an edelbrock

    Hey everyone, finishing up the carb swap on my 88 C1500 and I’ve been reading a lot on this forum. From what I’ve read there seems to be a lot of talk over an electronic fuel pump, I don’t believe the 88 model had an electric fuel pump isn’t it manual? Correct me if I’m wrong What would be...

    Haven’t posted here for a while hope everyone is doing well. I’ve got a tbi 350 in my 88 C1500 and I'm planning on switching over to a carb setup. I’m well aware that TBI heads are inferior to vortec heads but let me explain why I’m keeping them. My truck has been running way rich for a...

    Engine Running Slightly Rough And Code 42

    Recently I did a cam swap in my 1994 k2500's TBI 350. After which the engine ran quite smooth and I was pretty happy with it. Over time however I started to notice it was progressively running a little rougher, like I could hear each individual cylinder firing more distinctly. The last...

    Trans Swap

    TLDR I have a 95 K2500 350 Suburban and a 94 k2500 454 suburban, both are 4l80e's. The 94 tranny (no 4th gear) is bad along with the torque convertor I believe, and the frame of the 95 is bad. Can I straight swap the tranny from the 95 to 94? if so can I swap the T-case, and Torque convertor as...

    Stock 350 3/4 ton transmission options

    Hey Everyone, my name is Ashton from Iowa. I recently acquired a fairly clean ‘89 3/4 ton Chevy with a stock 350 small block. It currently has the 3 speed manual which I find to be horrendous for anything above 55mph. I’m looking into the idea of a 4l80 swap and was wondering if anyone has a...

    Top end build worth it?

    Will I have to balence the rotating assembly on forged rods and pistons?

    I’m planning on putting high comp forged rods and pistons but keeping bore and stroke stock. I had someone tell me I will have to get my rotating assembly balanced. Is this true? I thought it was only if you change the stroke and bore to a 377 or 383? Thanks, Korbin.

    Good cam specs for build?

    So I had plans to do a 377 stroker but my 450r bike blew up bottom and top end and the suspension has been out for a while so I’m a bit tight on play money. Rather than doing an all out 377 build iv decided just to do a mild build on a 350. What are good can specs/can you recommend for the...
