    305 Vortec to 335 stroker

    383 stroker will get you exactly what you want. But I nice 350 a slightly bigger cam with supporting mods can too. 305 would just end up costing you more and you'll be disappointed. I've found out the hard way.

    Turbocharging a TBI 350

    EBL flash was the last thing I did and that helps a ton, and I know it's better than chip burning

    Turbocharging a TBI 350

    The truck is still around with the vortec engine and has headers. I have a gt45 turbo set up that needs modifications to fit. It seems like if I'm not at work it is pouring rain and when you don't have a garage it makes it to hard to work on it. Plans haven't changed just delayed. Plus I had 4...

    Turbocharged 5.7 TBI

    So my question is what does it really take to swap in an LS engine? Looks like I have a lot of reading and research to do.

    Turbocharged 5.7 TBI

    Dang I never realized how much boost you could cram in one like that. Will probably go with a ls or 454 what ever falls in to my hands. I would like to just try the turbo small block just to see what it is like.

    Turbocharged 5.7 TBI

    I know that 700r4 would explode with the kind of power a turbo sbc would put out

    Turbocharged 5.7 TBI

    You very well have a point on keeping it simple I will gladly take your advice since I have little experience with either transmissions but those are after a biuld the 4 bolt main sbc I'm saving. For this setup I was thinking cheap temporary experiment with a small turbo to get me started and I...

    Turbocharged 5.7 TBI

    sounds like a good plan personally fuel injection has the most benefits. The end result of the truck hasn't been decided so the allison is still on the table for towing and a sequential turbo setup would probably be used. I like axle breaking torque so the more boost at a lower rpm the happier...

    Turbocharged 5.7 TBI

    Definitely let me know because after a couple years working the crap out of this engine I'm going to biuld the 4 bolt main engine in my garage with something like that.

    Turbocharged 5.7 TBI

    Well what I was looking to do is have the way for guys doing this on the cheap with a stock engine and fuel system with some relatively cheap up grades but if I had the money to blow well...

    Turbocharged 5.7 TBI

    Dang I have the factory 10 bolt 3.42 gear with the g80 locker it's been great so far and I get really good mileage right now I get 18+ when I keep my foot out of it. Night and day difference from all 3 of the previous engines. This engine will definitely get a turbo after I iron out a few things...

    Tbi Vortec swap ignition problems

    Yeah that's what has me puzzled because the cam was installed correctly, distributor was installed and set correctly, and it still acted like it was 180 out

    Tbi Vortec swap ignition problems

    Already have an external bypass. What doesn't make sense it back fired out the TB blew compression out the intake. It runs now thought but can anyone explain because it sounds like it was 180°

    Tbi Vortec swap ignition problems

    I eleminated the oil pump as part of the problem and it is a big block pump. turns out the dizzy had issues with the cap actually, the battery that was "good" only had 43% charge, and plugs that I left in where fouled.

    Jerking in overdrive?

    Possibly the TVCable needs adjusted I know that can effect things but not sure in this case

    Preparing for road trip, any suggested maintenance?

    If you have an engine oil cooler (most of the 4wd trucks do but sometimes I get a surprise that one is not there) but they gave me problems and can often leak. I deleted mine because I believe that on high mileage engines it isn't very good to have the factory cooler setup because usually you...

    Tbi Vortec swap ignition problems

    So what should have been a simple swap has kinda turned in to a huge head ache dealing with ignition. This is a 99 vortec block with stock cam lifters and heads the rotating assembly is from an 89 TBI engine (extremely low budget rebuild) all new bearings and also has a big block chevy oil pump...

    Turbocharged 5.7 TBI

    Judging by the description of your truck it sounds like a fun truck to drive. The throttle cable bracket is different than on my truck and I guess I can make the factory one work for now if there is a bracket for this swap it would keep things clean. But if it looks hacked and works fine...

    Turbocharged 5.7 TBI

    Alright I know it's been a couple of months since I posted an updates but this is what happened to the vortec pulled from the yard. I ended up using the Vortec heads. I was going to use the tbi heads I had from the orinorig engine but after attempting a valve job tbi heads and then comparing...

    Turbocharged 5.7 TBI

    While yes more gap will make it run crappier off boost for say. A naturally aspirated engine ring gap would be .0045 per bore inch and an engine for 15psi and below ring gap would be .0055 per bore inch. The compression ratio of 9.3 and it will build boost at 1000-1500 rpm I don't think I want...

    Turbocharged 5.7 TBI

    Ok so I decided it would be okay to gap the rings but how much should I gap them for this engine. This engine will only have 6 psi 95% of the time the other 5% will be when I finally get bored and crank it up some to 8psi. I will be getting new rings and bearings because of pitting on the...

    Turbocharged 5.7 TBI

    So we pulled heads off the engine and found a crack in the block between 3 and 5. The head gasket blown in two places. Then when we knocked out number 5 and it fell apart in my hand in little tiny bits. :Whoa::wtf2: Has any one had this much bad luck out of 4 Chevy small blocks at one time...

    Chevy G20 350 V8 5.7 Smog Pump Delete

    LOL only if you'er in first gear any rpm and or let off it above 3,000 rpm not letting the trans up shift. A single pipe sounds better to me any ways especially a 3.5in some people think I have a Big Block and the tone is super deep plus peoples faces when i point it out. I have it exit in the...

    Turbocharged 5.7 TBI

    So has anyone drilled the throttle body to pressurize the throttle shafts. I found one web site about using a throttle body spacer but couldn't you drill from the top?

    1991 Chevrolet C1500, the gas saver

    Right I know what you mean. I am actually working on putt a Redneck turbo system on my truck for fun. I am curious to see what kind of mileage I will be getting. I also thought a turbo 4.3 would have plenty of get up and go while getting good gas mileage. But all these ideas cost money. Making a...
