Just asked for an update - to be honest it's one of the last things on my mind right now.
 
Yeah, the dark side, as in an oil burner that produces real power:flipoff2:
 
Yeah, can't get any power out of those LS motors :censor:
 
I've owned an LS motor vehicle and spent enough time on a school bus to know that both of those options aren't for me :)

A ricer, through and through.
 
Nah, I have two land cruisers with Chevy 350's. I also had a suburban with the LS, and a Buick with a 455 so I'm no stranger to American muscle. I'm definitely not a ricer. That said, I do love boosted engines.. :)

Closest thing I've owned to a diesel were an 81 Rabbit and 83 Peugeot. Both gas, but sounded and drove like diesels.
 
I could give you an easy formula to hit over 400ft/lbs in that Tbi for around 1.3k.

that may tide you over for the two weeks it takes you to get the boosted 80 back.

Any real updates from the shop? I'm still hopeful that this thing will be running this year.

Ok let's hear the formula!

This was a few years back that a friend and I did for his 3rd gen camaro. Quite a few of the parts we got from the huge pamona swap meet or ebay so the exact cost will vary. But even all the parts brand new from retailers aren't terribly expensive. Many of the parts were brand new but the pamona swap meet is pretty much the biggest car parts swap meet in the country and things can be found and haggled for for cheap.

Stock L31 vortec heads- .050" machined off the valve guide, slight porting to the exhaust and 1.6" valves installed. Valve springs were swapped out but i'd have to get the specs off my friend as I don't quite remember what they were. (EDIT: these are the non LS based heads that for some reason got stuck with the vortec nomenclature also, these are GEN I small block heads from a chevy truck 350 96-99, they are identical to a GEN II head except they aren't reverse flow cooling so will still work on a GEN I engine)

Comp cams 8-304-8 roller cam (i'd have to check and make sure of that... I still have some notes in my car journal but want to make 100% sure)

You may have to upgrade your fuel pump depending on what one is in the 60 but I wouldn't do that unless it is needed after.
Stock 350 injectors at 18PSI with an upgraded spring in the FPR (or you could just change to an adjustable FPR if wanted)

Bored out TB to 46mm from one of the shops that does this (although this we just bought brand new from the swap meet, there are shops that do this RVmachine is one of them)

for the exhaust he already had a set of shorty headers lying around, had an exhaust shop fab up an exhaust using a thunderbolt cat (although you don't need this as you don't need to smog) and the most important part was it was built around a flowmaster collector part number Y250300. I don't remember the muffler type... thrush or flowmaster I think.

The intake will need replacing as the stock tbi intake manifold won't fit the vortec heads. There are many of these out there one is the edlebrock 2716 but check out summit for other part numbers. (that one does not have the provisions for egr so you can scrap it)

For air intake we just used an open element air cleaner.

Custom chip burned (TBI chips is most likely the best) They can burn it for your exact mods.

Also i'd consider upgrading to a 3 wire 02 sensor. I think TBI chips also sells that aswell as the spring for the FPR.

For that he hit 286HP and 351lbs on the dyno. A 700R4 would most likely have at least a 20% loss from the engine.

i'll edit or update this if I find out my part numbers were wrong.

Also depending on your year of engine it may or may not be able to accept a roller cam and you may have to go flat tappet instead.
 
I will most likely be going this route on my current rig while i'm building a stroked out all aluminum 383 LS motor to throw in there.
 
oh forgot 3 things.

The new intake will need a TBI spacers/adapter for the tbi unit as that is a straight carb intake manifold.

He managed 27 mpg out of this (obviously it would be a lot less in a lifted 4x4)

And if the dizzy is original i'd replace it. The TBI dizzy's were terrible. GM made an updated version that is around $200 new or there is a few good quality cheaper options also.

Did you say $1000?

More or less around 1.3k, as I said not everything was brand new the best thing about chevy engine are cheapness of parts and availability of good quality used parts.

These may have varied a few bucks up and down but this is what he told me when I asked him a few nights ago.
Vortec heads were around $100
Bored throttle body was $250
Cam was $125
Chip and spring for FPR was $200
Exhaust was $300
Intake and adapter was $300
Open element air filter was $25 or so from local pick n pull
He can't remember how much it was for the minor head work or new exhaust valves but remembers that it wasn't that much at all. If he finds his receipt he will let me know.


Prices on used part will vary but the only used parts used were heads which last night I found a bunch of them a stones throw from me for around the same price, the headers which I found for as cheap as $80 and the open air element filter which may or may not be an easy find at a pick n pull these days but is pretty easy on CL.

All others were new.


The lynch pin here is the chip... TBI will not respond well to these mods and especially the cam without a tune from a specialist. As such most TBI build ups have to be done all at the same time or you will be forced to keep swapping the chip out. It's not a very tolerant system compared to TPI, early Vortec, LT1 or LS based systems.


James a great place to find most of these things would be the very large auto parts swap meet at the charlotte motor speed way. Next one should be around in september.
