lt1 swapped tpi. check it out if you own one. pics inside
i have a sbc 350 w/ a lt1 intake. I did the conversion myself and all the machinening myself with the help of my dad. My car went 4 tenths faster in the 1/4 w/ just the intake upgrade, ive had some issues with it but i'm really happy with it. The only thing i hate are how all the houses and wires look in my bay.
I wanna see pictures of other sbc with lt1 intakes to see how you routed your stuff.
My car has had a lt1 intake for almost a year now, love it, but i'm tired of a messy bay soooo.....
i took the intake off, painted it, ported it, and i will figure out someway to make everything look stock, idk how tho, so please help me.

Where did you source the slicone piece that adapts the throttle body to the 3" tubing?

I thin kit's 4" to 3" or 4 1/2 to 3"..
I don't have a miniram anymore, this is what I'm running now:
Oddly enough, the same adapter works on the LS1 throttle body because the outside diameter is the same. (just not oval, but thankfully it flexes to whatever shape I need)

WIRING LOOMS! If cleanliness is what you desire then wiring looms you must aquire! wires laid across valve covers and plenums? for shame! In looms they must go! mounted to firewalls and frames! Tidy it will be with wires out of sight. good day to you all and to all a good night.

Now that i look back at it it wasnt that hard of a conversion, cheap and fast. i might have spent close to 180ish.
LT1 intake+fuel rails -> free
lt1 AFPR-> 100
remote tstat-> 70
misc hardware (hoses, fittings)-> 20-30
machine job->free, my dad is a machinist and we have miling machines at home

Go get some split loom, the plastic tube that the stock harness is in. Clean the plug wires up with some acetone, or replace them. I think you can get some at radio shack if you want new stuff, or the junkyard for way cheaper used stuff.

LOL
it is not a real lt1. It used to be a tpi, but it has a modified lt1 intake, it has a distributor hole, and modified hole pattern, and water port. it is something pretty straight forward, check out www.lt1intake.com for more info. it is very simple to do if you have access to the right tools.

Re: lt1 swapped tpi. check it out if you own one. pics inside
I bought it pre-modded from a board member for about $300 everything included
The intake holes were slightly off but nothing I couldnt handle
Its been on the racecar for about a year now, no issues
Whats everyones gripe with the remote thermo? Its extremely handy
You can literally mount it ANYWHERE
I had it in the initial position you see because I was too lazy to get more tubing and just used a few bits of original heater hose. A few weeks later I got longer hoses and mounted it on the framerail
The current project needs that area so Im moving it again to the cyl head
Id like to see you move a fixed thermo around like that

Re: lt1 swapped tpi. check it out if you own one. pics inside
ok so heres a lil something. As you can see i still have alot to do but the weather is not helping, it was raining when i took the pix. I still gotta hook up the fuel lines, throttle cable and a few more wires. Def. getting rid of that air cleaner and going with something better
The engine bay is flat black so everything stands out, i ordered a blue throttle cable bracket like two weeks ago but apparently it was on backorder so i'm exchanging it for a red one tom. I also ordered the heater box without AC and i should get it tomorrow. My goal is to finish it tomorrow or at least get it started since i dont have to work or have no classes. We'll see

Those of you that have bought an intake already machined, where are you getting them? I've got an intake I can send out that's ready for conversion, just gotta find someone to do it.

Since the OP removed the LT1 intake in favor of a carb intake, I'm locking this thread. I imagine from now on updates will be posted in the carb board.
