Give me a 427 sbc with aftermarket performance heads..the best motor made by Chevy

--- IT LOOKS GREAT MAN BUT. Get rid of that fuel filter and upsize it because that inlet and outlet on that fuel filter is way too small to keep the fuel supply that you need flowing..

[@Roddy_Zeh]

This got me wondering if the other way around (LT block with LS heads) is possible. Specifically, the L8T block with LS3 heads.

[@Macburton96]

Suppose you could, wouldn’t be able to use the direct injection, and you’d need to remove the fuel lobe and line up the accessories

[@Roddy_Zeh]

@@Macburton96 Yes, the main objective would be to ditch the direct injection and use the LS3's indirect system. Unless it's possible to convert the LT heads to use said system. If it's easier than adapting LS heads...

[@Macburton96]

So this video is actually quite old, since this I’ve done mpfi and then supercharged the engine, the LT heads are what is good about the engine, you can buy a plug kit to cap the direct injection holes and then get an LT style intake with port injection, or the other route is to get ICT adapter plate to go from an LT head to LS intake but all very do-able now, market is starting to fill up with options

[@Roddy_Zeh]

@@Macburton96 Now this I didn't know! Nice! 👏‍

[@reecejewell1018]

Can I use a 350 transmission with a adapter plates for the 5.3 LS carburetor

[@FPJblues]

Yes

[@forged_billions2]

We’re is the advance vacuum line going to from the carb?

[@Macburton96]

The msd 6014 has a 2.5 built in map sensor that goes to vacuum port on the intake

I just saw BTR has a kit for this swap.

What headers?

[@Macburton96]

1998 Fbody headers, got LT header flanges from motion race works and welded it all up

Decent power?

Definitely picked up a bunch compared to the previous setup

[@morganpowell2999]

@@Macburton96 interesting. I’ve just heard those adapter plates for the LS 4150 style manifold to the LT heads kill flow. What was your previous setup?

[@Macburton96]

@@morganpowell2999 previous setup was summit stage 4 cam, 799 heads, single plane intake and same quick fuel carb in the video, the plates might kill flow a bit, back then if I was smarter I should have gone with the LS7 to LT plates instead of ls3, the ports are more evenly matched, but I haven’t had this setup it a while it’s an old video

[@morganpowell2999]

@@Macburton96 nice, I figured I’d ask how the power was because I know flow numbers aren’t always indicative of power. That’s pretty good if it was up from that previous setup.

[@Macburton96]

@@morganpowell2999 I never dyno’d that setup, both cams were almost identical in spec, from the seat of my pants there was a significant difference, the LT heads flowed better and they were L83 heads with 56cc chambers, I had done some home porting on them and the bump in compression helped too

[@dridiott]

Running the same setup on my '78 TA but what did you do with those dang steam lines in front? Looks like you ran them back?

[@Macburton96]

The newer LT engine deleted steam lines, since I have LT heads I didn’t need to run steam lines

[@TheRoadhammer379]

You can get a 3 way inline coolant adapter, it goes in the coolant hose and has nipples to connect steam lines

[@hitmansniper1368]

Not working good

It doesn’t work good, it works great😂

What all would I need to carb swap my 02 escalade 6.0

Ls carburetor intake, MSD 6014 to run your ignition, prob need a new fuel regulator because the stock fuel system puts out 45 psi and you’ll need 6 for your carb

[@TheRoadhammer379]

go watch nightwrenchers vids he's done probably 30 carb conversions, some with blow through carbs and turbos. he has a shit ton of vids on everything you need

Why

[@Macburton96]

Stock Lt heads will outflow most aftermarket Ls heads, pick them up for 500 on scoggin dickies, BTR sells a stage 4 cam to make the heads work on an Ls block for 399 and get a LST efi intake @ mast motorsports for 650, your 6.0 or 6.2 is pushing 600+ EASY with room to grow for 1500ish bucks, LS aftermarket heads/cam/intake upgrade…3000+…..that’s why
