the boat engine 4.3 had a carb intake and crap on it. so all you have to do is find a boat 4.3 with a carb swap intake and carb. regulate fuel pressure and do some other small stuff and there ya go
You can’t …… vortec 4.3 engines have what’s called a balance shaft, which mounts in the intake valley under the intake manifold , they don’t make a carb intake for a 4.3 with balance shaft and the non Vortec intake won’t physically fit the Vortec engine due to interference from the balance shaft , most people take a 91 and under non Vortec 4.3 and slap Vortec heads on them and run a carb setup that way , the Vortec heads flow much better and it retains the same mounting points as the non Vortec edelbrock intake To convert to carb in a already tbi vehicle you need to know if you have a mechanical or electronic valve body transmission, meaning 700r4 ( mechanical ) or a 4L60e ( electronic ) this will determine if it will be cheap and easy or expensive, it’s easy either way but if your transmission is electronic controlled then you would have to buy a aftermarket tcm to control the transmission for shift patterns , rpm’s etc which runs a extra $700-$1200 for the part needed Next would be fuel system , you can either keep the factory fuel pump that’s setup for tbi and just add a fuel pressure regulator to turn the fuel pressure down to 5-7 psi for a carb or you can redo the fuel system entirely by taking the stock pump out the tank, replace it with a fuel pickup and then add a Holley 5-7 psi pump in line off the frame Next would be ignition/ distributor , it’s very easy to grab a Hei distributor , this would do away with coil and all the wiring for a ignition box , all you need is power , ground , and rpm wire That’s the basics of doing a carb swap 🎉
Bro there's actually nothing wrong with a blazer. My parents to this day still have one as a daily drive and it's still kicking after 350k miles 😅 it's not as good as the Silverados or big main stream 4×4 but they can still get it done
@@xXPentEntityXxyep especially u throw a jeep front differential in it like solid axle it and a decent lift and just maintain that 4.3 that will wheel hard
