Hello all, been lurking on here watching a few builds for awhile and had a bright idea last week to pull my newly built 331 stroker out and go LS.

Figured I would make a build thread to document the progress. I currently do not know how long it will take me to complete this swap.

I have had the car for a little over a year now, car has suspension and some chassis modifications. It should be fairly light as well.

Build Goals:
5.3L
ON3 Kit w/ 78mm
LS1 Intake
LS6 Cam, new springs
Head studs
Microsquirt
TH400 or Glide.

Here is what the car looked like when I purchased it.





After some suspension




We threw in a buddies nitrous 351w and had some fun for awhile while I was building my SBF 331 Stroker.

With a good friends help we ripped off the GT body kit, added the LX bumpers/panels and dropped in my 331.







So today, I started pulling out the SBF and picked up a 5.3L

Picked up an Fbody oil pan and ordered a few things such as, Headgaskets - Fbody pickup tube, dipstick - Fuel Pump, Pre & Post Filters, Regulator - On3 Turbo kit W/ 78mm turbo - Paid a local guy to build a powerglide for me and a bunch of other things. Pictures of some progress below.

Heck yea! That's a good parts delivery!

Looks great. Why an external fuel pump? Can you not just put a more powerful pump in the tank?

matt_u

I no longer have the factory tank just the aftermarket 10ga cell or I'd do an in tank pump.

Anyone have any experience with a glide and say.. 3.27 gears on the street? Car will mainly see the track as I recently purchased a trailer, but would still like to drive it around on occasion.

Also thinking the car is going to be alot quicker now so after I get it running, its time for a better cage, better rear end and minitubs.

MalcolmV8

Ah makes sense.

matt_u

Few more parts came in!

80lb Injectors, 3 Bar MAP, PAC 1218 Springs, Fbody windage tray, dipstick, LS9 Headgaskets and an AEM Wideband

I should be getting around to gapping the factory rings and starting to put the engine back together this week, put an offer in on a house today so progress may slow down temporarily.

Paid for my Powerglide today, picked up an LS1 car intake and, gapped the factory rings..... jeez thats some tedious work.

MalcolmV8

Why not an LS6 intake? From what I read they outflow the LS1 intake.

matt_u

Picked it up for a good price with a DBC throttle body.

Not super important when boosted

MalcolmV8

But it still flows better and makes better numbers when boosted doesn't it? I realize the gains would be more pronounced when naturally aspirated.

Probably not as you would think

What 3 bar map you go with? what did it run with the 351 and 331 setups? Nice project.

matt_u

I ordered the injectors and MAP sensor from EFIsource.

The 351 was stock bottom end with a set of 185cc heads and a 200shot it went Mid 6's.

The 331 was N/A and only taken out once it went 7.1.

Thanks I am a long way out but hopefully will be making some noise this year.

Have a few more pictures of the progress. Slowly but surely it's coming along.







Gapped the rings


New Intake


Threw some heads from a 00' Vette on the motor along with the PAC1218's.
