    TBI350 to L31 swap. I'm told close to impossible.

    I actually list that as an option, my point is if he wants an easy swap and have it run correctly without tuning/buying anything swap the oil burning short block for the Vortec one but keep everything else from the old motor.

    TBI350 to L31 swap. I'm told close to impossible.

    Easiest way to do this just swap short blocks but use the TBI heads, intake, FP, WP and accessories. The roller cam is probably even worth a few HP. Have the Vortec heads checked for cracks and either sell them and the Vortec accessories and intake, or when you have time and money get a carb or...

    305 Is a Turd Correct?

    The 307 in my Nova ran strong but it had aftermarket cam, intake, 600 carb, headers, and some 1.94 valve heads.

    305 Is a Turd Correct?

    305 Vortec makes a little less tq than a TBI 350 but a little more HP so yeah if you have some Vortec 305 heads and have a roller block you can upgrade then go for it.

    Code 32 with a high flow exhaust.

    If it is running fine I would not worry about it, maybe a tuner could eliminate EGR like on the 96+ trucks.

    305 vortec heads and factory intake on old block??

    My 73 Nova had a 350 and the sky roof(which leaked and the engine blew) really love those years 68-79, I owned several.

    305 vortec heads and factory intake on old block??

    It might not be the original engine in that 77 and i believe roller cams were 88. Check the casting #s to find out.

    Oil Filters with good anti-drainback valves?

    My last oil change was with the usual Wix filter that was made in USA I believe in Illinois. They also made the Bosch one, I think exactly the same as Wix/Napa Gold and I bought quite a few on Amazon, so look for that filter too while they are still out there.

    90 truck with 86-87 Corvette engine

    If you are not going TPI then stick with the truck's dizzy.

    Keep Manifolds or get shorties?

    Shorties help top end which matters more in Vortecs than TBI, but if you are doing the whole exhaust anyway might as well go for it.

    Has anyone used a Holley 2 Barrel on TBI adapter plate

    If you are going old school HEI/Carb just get an intake manifold from Edelbrock/Weiand/87-88 Monte SS and put a Holley 4 barrel on it.

    Big mother thumper cam in a 89 350 tbi, is it possible?

    I'm guessing he just wants the sound. I'd look at Isky cams, they have cams that lope but are mild.

    L98 into K1500--> HEADS?

    It's not a 113 head if it is an 87 and original. They had the 128 head, which flows less over the exhaust side, has factory guideplates. If they check out sell them to a Vette owner and buy aftermarket heads., unless you really want a GM al head then send them to Lingenfelter for porting and...

    LT1 2nd gen version power steering question

    You might look at what 94-96 Caprice used for lines.

    Fuel gauge issue, but very specific situation!

    Maybe you need the 98-00 gauge cluster?

    305 TBI Header (?)s

    A relative of mine had two good 305 TPI engines I could have had dirt cheap a few years ago, i did not get them because you know 305s but i wish I had as @L31MaxExpress said good 350's disappearing fast, and 305s/334s can be good runners for daily driven trucks.

    Chevy distributor cap condensation issues

    Do a search here for the UMP cap at RockAuto or look at the reviews at Summittracing, the Summitt cap is the same as the UMP one.

    Low Cost Camshaft Options - Need Opinions

    If it is a TBI engine with Vortec heads then yes Summitt 8800, basically a roller version of that old Melling RV cam.

    Ignition control module

    Did you change your rotor? That was my problem with that code. Also I have had bad Delphi/Delco parts but Standard seems to be good, could just be dumb luck though.

    Head Swap Options For 5.7L 350 TBI Engine

    Ya sure but I believe he is talking stock heads not Mexican Vortecs so no real difference. I still think his best bet buy new heads either Jegs Vortecs which are less $ than the GM Mexican ones, or Trick Flow 87-95 heads and no worries about changing intakes/water pump but obviously cost more...

    Head Swap Options For 5.7L 350 TBI Engine

    906 and 062 are the same head anyway so no problem there, I think the difference in casting #s is two different plants.

    Are United Motor Products distributors adjustable for Cam Retard?

    You need the GM hold down to adjust it, and the code doesn't pop up unless it is +-13 I believe. My UMP ran better with a Standard cap, though I didn't have their better cap.

    880 vortec blocks, what pistons?

    You can buy a ZZ short block but it is like 4k.
  25. 98 Nitro

    Need assistance!! Please, any input is welcome...

    I think he just needs the stock adjustable hold down, that UMP one comes with a non adjustable clamp.
