To run a Carb or not?

rockauto for spectra prem tank and sender MINUS pump option and then the acdelco pump if you want that one . use the 5% disc code in the vendor section .

but also check ebay for the part#'s i found tanks a few bucks cheeper there when i did mine .

stay away from the china cheepy stuff tho .
 
So roughly this could be if I install it myself about $3000.00 ballpark....

If outsourced potentially upwards of $5000.00 ballpark?

Even with a slightly higher quote if outsourced, it is still significantly cheaper than an LS swap, correct?

There is no way I can LS swap my truck. I just don’t have the room in my garage. So it would have to be outsourced.
 
Me too. Apparently the 381 is just under the LPH rating. Of course that is a full throttle requirement....
I’m probably not using enough fuel for it to be a concern then.
I'm very interested in this. Last time I towed the camper up to the mountains, I really wondered if it wasn't getting enough fuel at the higher rpm pulling the passes. I haven't had a chance to try again now that I can see fuel pressure in the cab.

If fuel pressure drops off at the higher RPM would that indicate the pump isn't able to keep up?

For BroFlow? I would think you would be closer to $2500, but I'm not sure what you're looking at doing along with it.

Assuming your filter, regulator and lines are in good shape then yes, your pump would be the problem.

I'm running the factory TBI hard lines and filter. But there could be a restriction at the tank selector valve. I know it's okay for the pressure, but come to think of it I've never seen anything listed about flow thru them.

Flobro and fuel system... yeah about $2500 for me to do it. Which would probably take 1-4 months for me to finish.

Shop about $5000 I would say.
 
Hard part is most shops might not give you a set price to do the install unless they've done a few of them. They would probably say their shop rate is $125/hr and the total cost will depend on how many hours it ends up taking them.
 
The Edelbrock kit comes with the O2 bung and a plug so that you can take it to a shop, get the bung welded in and then drive home to do the installation of the rest of the system.
As Bent said, it isn't too hard to do. Running the fuel lines so that they are protected from abrasion AND heat can take some time. The wiring can take a little bit of planning because you have a lot of options for ECM mounting. Inside or under the hood. I like the idea of having the ECM separate as I can unplug it easily if needed. I put mine in the factory ECM tray behind the glove box.
 
Got dang guys. An ls swap is simple stuff. Y’all make it sound so difficult. It is literally the opposite. DM me your contact info and I will share whatever info I have. I have no problem helping a fellow ck5’er. My swap is running like a dream and I want nothing more than helping more squares hit the road.

Where did anyone say an LS was difficult? I sure missed that.
It isn't just buy the engine and bolt it in, though. Difficult, no. But the parts ( $$ ) can add up.

Agreed that it's not that difficult. With the swap brackets the LS drops in like any small or big block.

Depending on how you want to take on the swap makes it more or less expensive and to a certain extent changes the level of difficulty.

One guy might buy a wrecked truck for a donar vehicle and harvest all the items needed including the harness. The rework of the harness isn't overly difficult as it is time consuming, but some don't want to go through it. Aftermarket harnesses are good options. Still the stock ECM needs tuned to eliminate the security and any emissions monitors not required that could be above someone's skill level. Options are to by the tuning software and learn to do it. Another is sending the pcm for programming or just taking it to someone.

Others might not have the time or space to dismantle another truck to get the engine and go through an outfit like Tilden to get the engine/harness/PCM ready to go in one kit. Costs more but saves time. Time is money after all.

There is no one and only way to do it. Many ways and variables based on what you start with. To a novice it's a daunting task. To a seasoned guy it might not be that hard. We have that range from complete beginners to experts here on this forum that what may be easy for some isn't for others. Just comes down to how they want to get it done.
