New engine options 1993 K1500 5.7l tbi 4l60e

[Jskingry]

Hello,

So I should get my truck back from paint this week, the interior and exterior will be done and now it's time to maybe investigate making this truck a little more powerful but definitely more reliable.
I would love to say money is not an object but we always know it is. I have two options I am looking at and just wanted to see if people had cautions or experience I can draw from to make the right engine decision. I do want to keep the engine running on 87 octane so not looking for a hot rod engine.
Option 1:

GM SB Compatible 350 c.i. Engine - 341 HP - Base Dressed - Fuel Injected

BluePrint Engines 350 c.i. small block GM style crate engine - dressed NEW BluePrint Cast Iron Longblock with fuel injection. Includes 30 month / 50,000 warranty & BPE Dyno Promise. Part #: BP350CTF

This is a nice looking engine, ready to drop in. I have started researching the Holly TBI units and reviews are not kind. Additionally looks like this will not control the transmission and my cruise control will probably no longer work. The engine makes good power and still allegedly runs on 87 octane and uses the stock torque converter.
Option 2:

GM SB Compatible 350 c.i. Engine - 341 HP - Deluxe Dressed - Carbureted

BluePrint Engines 350 c.i. small block GM style crate engine - Base Dressed NEW BluePrint Cast Iron Longblock with carburetor. Includes 30 month / 50,000 warranty & BPE Dyno Promise. Part #: BP350CTCD

Buy the carb version and get an adopter plate for my TBI, of course I will need to mod my TBI to support this kind of air/fuel flow needed. The positives here are Stock TBI is very reliable, controls the transmission, and should be able to get the cruise control working.
Option 3:

TBI Truck 1987-1995 - GM SB Compatible 350 c.i. Engine - Long Block

BluePrint Engines 350 c.i. TBI small block truck 1987 -1995 GM style crate engine - dressed longblock. Includes 30 month / 50,000 warranty & BPE Dyno Promise. Part #: BP350TBICT

Something like this, it's made for my manifold and TBI to bolt right one. 260hp is a nice bump but not as nice as the 341 from the other 2 options. Positives are stock TBI, transmission, cruise control.

I am brand agnostic I only chose the blueprint as they have the full range of blocks/engines. They are expensive but appear to be fresh cast blocks and high quality.

First Option: If the Holley Sniper won't control your transmission, I'd pass. Ignition timing is not controlled by the computer; I suspect there's no knock-sensor. No EGR. Not emissions-legal. I'd think the cruise control would still work unless you disable the DRAC.

Second Option: Why buy a carb and distributor you don't need? At best, you could recover some cash by selling them. No EGR, so you'll be tuning the computer, and it won't be emissions-legal.

Third Option: The easiest-to-deal-with of the bunch. Not emissions-legal if that's a concern.



The Blueprint blocks have no cooling system bypass, they'd be a poor choice on any vehicle that has a heater valve that blocks flow under some conditions. I'm not enthused about drilling the thermostat.

I agree with @Schurkey that option 3 would most likely be best how ever this may also be a good choise it from blueprint it is a 383 vortec you would need a 4 barrel intake for it and a tbi adapter https://blueprintengines.com/collec...tec-383ci-stroker-crate-engine-small-block-gm

Or, the GMPP intake here which appears to have provisions for EGR too. Just order it, don't look at the price

it is a real shame that is the only tbi vortec intake on the market
