This is a new vortec build 5.7 liter converted to 750 CFM Edelbrock carb first run on the stand using a vortec intake from Edelbrock set up for a street rod
Any vortec will bolt up to a Chevrolet trans they did not change the bolt pattern you will need a different flywheel or flex plate the bolt pattern on the rear of the crank shaft changed the TBI and vortec's have the same crankshaft bolt pattern pre TBI engines IE 1985 and earlier have a different crankshaft
Should I pull the 5.7L vortec out of my escalade.? The registration is 4 yrs now old owe $1,000 in late fees. Ive had it at my parents pad just sitting. I Procrastinated big time, but i had another car so I was not trippin. kept saying I would get it smogged but shit wasnt in my name. Im most likely gonna get another Gm truck or suv, but I dont know much about cars, could I swap that engine in another gm truck or suv right?
@@jimmycope5421 yes, but make sure to check if your vortec has the double holes on the passenger side of the water pump inlet on the block. if not, drill holes in your thermostat. if you dont, itll overheat.
I have a 1996 5.7 l Vortec with Edelbrock performance intake manifold how do you switch over from fuel injected to carburetor do you have a video of the process of switching that over
@ In stock form they won't win any drag races. I think around 255 horsepower and great torque. But the L31 cylinder head is a great upgrade to an older style small block chevy. (requires an intake manifold swap as well because the bolt pattern is different) The real downside to the L31 is that they only made it for a few years. 96 through I believe 99 before switching to the LS platform. So at this point they aren't "as" plentiful as say a 5.3LS. But they are still real easy to find because GM sold a lot of trucks and SUV's with the 5.7 L31 in them.

@@Shane-Singleton They are getting a little tougher to find in my pick and pull. About a year or so ago though they were plentiful. I pulled about 3 or 4 880 blocks to be used as basis for building a couple of boat engines. Volvo Penta used these with the vortec heads for their FI engines.
What Hei distributor are you running? I know a msd or something up there is best but been looking for a more budget friendly distributor which there's like 1000 brands out there nowadays lol but I know some are completely trash and u get what u pay for but there are also some decent brands that are budget friendly and still reliable just not sure which to go with lol
6 years to late but what the hell 🤣🤣 maybe someone will find the info useful....If your wanting edelbrock go with the RPM Air gap, its pretty damn hard to beat for a street engine, being a stroker you could probably go with a taller single plane intake and still have plenty street manors but honestly those Rpm Air gaps are just perfect for a built street engine with some cubic inches. I'll never use anything different on any 350 or 383 I build there's just no point in doing so and if you got some decent flowing heads then all the better 😁
Pull the intake and get some new gaskets and clean all mating surfaces extra good then apply a good 1/4" silicone bead in place of the front and rear gaskets and especially in the corners. It shouldn't leak after that. And while you have the intake off check your oil sending unit for leaks
Sam Loudermilk the guy I had put it on put the wrong gasket on number one cause it was leaking air also but I found out where the oil leak is coming from it’s coming from the oil pan got to get under there to fix that also smdh
that is a flat tappet cam,what year is your block? leave the stock l31 vortec cam in if you have a vortec engine or go bigger roller cam. it will run better,smoother,better gas mileage.having 4.56 gears and a turbo 350 means you can not drive on the highway,period .you will be revving at 3-4000 rpm at 60 mph
when you hook the fuel psi regulator up,do you run it straight from the fuel pump in your tank to it and then to the carb,also would it matter if you used a fuel pump from a tbi(88-95pickup) instead of the vortec(96-99)pickup,thanks
You don't need a vortec intake it won't bolt to the TBI heads on the 91 engine but a regular 4bbl intake will you hafta slot the 4 middle holes on the intake and Jegs or summit has some collars for the 4 bolts in the center. HEI distributor and an adapter plate for a spread bore carb( if using a Quadrajet) and whip bam boo mine fired right up bo and sounds great.
What all is involved in the conversion besides a new intake and distributor? I have heard the worm gear on the distributor has to be for that specific cam? Also can you use a block mounted mechanical pump or do you have to use a frame mounted electric pump?
did you find solution .... I know camshaft needs to have provision for mechanical fuel pump. did you find camshaft that has pump lobe that works with stock vortec valve train setup?
you need a melonized gear for your distributor,i just drilled out a gear from a tpi distributor(which was undersized diameter) and reamed it to 0.491"you can buy the melonized gears from summit,jegs or general motors.most L31 blocks are not drilled for a mechanical fuel pump,mine isnt.you can have it drilled and tapped to accept a mechanical fuel pump but i dont think its cheap(machine shop)
i have a couple chev 4wd's that im putting together and i got a 95 with the vortec 350 but the guy i got it from took the engine harness, can i bolt a carb to the stock vortec intake using a 2 - 4 barrel adapter plate?????
Whats the fuel to air ratio setting on the carb? What jets etc? I have a new 750 holley rebuilt carb on mine untuned for any car and its way too rich... got the engine converted to carb already. Help! Lol
The A/F ratio is controlled by the jets if it's to rich you will need to change your jet size the adjusting screws are only for A/F at Idle everything off Idle is based on jet size
Just running a Holley is your first mistake lol find a good q jet and run that it will be way better on fuel if you stay out of it and be a lot more dependable for street use dial it in and no Holley will match it's performance ..
what spark plugs did you use on it. I have a 5.7 vortex w/ 906 heads I believe that came out of a 97... carb converted with a 600 cfm edelbrock and an edelbrock rpm eps intake, but it diesels when I shut it off and timing is at 12° before tdc. it's horrible on highway and this is a crate motor with about 60k miles.
also, 5.0 vortec dont actually have "vortec" heads. they are a different design and dont make as much power, but are still miles ahead of any older 305 head.
supri45 It's always best to break in a new engine with quiet exhaust if you run them with open exhaust they do sound Tough as you put it but the problem is you can't hear the engine. I do have some other videos of engines running with open exhaust
+Aaron Pedersen This one is hand built so it's one of a kind however they do sell pretty good run stands on EBAY it was just cheaper for me to build one rather than buy one THX
Can you build a reliable, daily driver like this? vortec, roller 350 with a carb? In my build, I've got spec'd a 46mm throttle body, which i've already bought and i'm waiting on my cam kit. Of course, last of all i'll be having a chip burnt for the TBI setup, but I was just curious, I know gas mileage will undoubtedly suffer. What do you think?
Gas mileage will not suffer nor will performance carburators do just as well on both ends as fuel injection they just need to be tuned and tuned more often is all
how is the timing set, and what timing cover is being used? I just bought an 82 c10 with a 96 305 that has been converted to carb and HEI and I'm having trouble setting time.
Jaime Huerta Fel pro, mr gasket, and edelbrock has gaskets for the vertec to carb intakes don't know the # right off but Edelbrock's web site has the info
It's I believe a 350 vortec crate engine. I was just looking at them online last night. 255 hp stock specs 290hp with 670cfi carb and dual plane intake.
there is a pipe plug in the engine by the distributor that can be removed and that is a great place to mount a temporary oil pressure gauge so you can run the engine out of the car like this guy did. Once the engine is installed in the car/truck you can use the same plug to mount your hose or sending unit (depending on which gauge you have/like) and run the gauge under dash in the vehicle.
