ok gm sells a "deluxe" crate motor thats rated at 330hp and 380lbs torque...well i found the engine for 2200$ without an intake, distributer, carb and stuff like that...also no water pump...anyways my question is if i would get a holley 670cfm TBI, and a vortex intake with a adapter would it be hard to run that motor off TBI? where would i put the knock sensor?? also will my brand new water pump and radiator be enough to cool it? and ill probably just use the distributer i have for now so i can get the motor in the car and get it running...i know ill definetly have to have a chip burned...other than that will everything work?

 

It sounds like your doing the standard 305 to 350 swap. All that you need to do is lay the two motors side by side and transfer everything over. You'll have to get an intake that is EGR compatible. Besides the chip you need to change the knock sensor and module. The knock sensor screws into the passenger side of the block right by the starter. The knock module is mounted on the driver's side firewall. You will be able to run the TBI, but you'll want to upgrade the injectors in the pod. The waterpump and radiator will work fine, but you might want to consider running a lower thermostat and a different fan switch.

i was thinking about that same swap. can someone list all the things i would need for this engine. its the GM Base 350.

 

i was planning on putting a holley TBI on it...think i will get better results out of TBI than carb?

 

I like it and so does Z28 boy

 

Gm performance has this new manifold and I think it will bolt up to the 350 ho vortex cylinder heads. Could you just ad a aftermarket tbi and burn a new chip. IS There any place in the block for the knock sensors in this crate engine? What about the fuel pump pressure? Can anyone give me a answer to all it would entail?

 

Yeah, it's called read my engine swap page on my website.
It's got all the answers and there really isn't anything I left out. If you've got a TBI vehicle then what I listed under parts needed is ALL you need. Everything from the bolts to the injectors to the eprom. The only difference is that vortec doesn't have EGR manifolds so you need to figure something out like keep your base timing around 2-4 degrees and run a check valve in it's place.

 

im having second thoughts about the swap...decided i may stay with the 305 do heads, cam, intake (little over 1k) then with all the money i saved not doing the motor swap get SFC, LCA, n2o, and a custom chip....im thinking this would be faster than just sticking the crate in there althought the 350 crate has more potential i dont need a extremely fast car....just want one anyways id be happy if i saw 13s on street tires...thats all i need

 

u guys know bout the
HOT HOT HOT article?

chp(or car craft) got 400 hp/tq outa this crate just by swapping a cam(hot cam)

just got a 350 roller block and am planning on this buildup...

they had to mod the heads to accept higher lift cam
but it aint a thing :lala:

i bet its very achieable numbers with a 670 tbi unit
and of course sum intensive chip tu ning

 

Actually it was 412hp with the RPM air gap manifold and 422hp with the victor jr single plane. It's a shame how the TPI guys are only making a hair over 300hp with this motor and the hot cam! Keeping TBI is definatly cheaper and faster .

 

yeah, but when you don't have the funds to buy your own equipment to burn chips and can't find anyone to burn a chip for you it throws a wrench into the system...

just something to consider if your modifying TBI. I've been hunting for someone to burn a chip for a while, but no one wants to...

Swapped a crate 350 into my RS 6 months ago.
Kept TBI.Used 350 truck injectors,Turbo City Throttle Body and AFPR,SLP Headers,etc.
Custom Chip from Ed Wright at Fastchip.com.
If you can't(won't)burn your own, Ed Wright is a good solution.If it's not right, he'll work with you until it is.
Mine works great.

is a 350 chip from a caprice a good start to begin burning your own chip or is thier something better(ie feul curve.etc) i can look for?



:lala:

the ed wright chips r bout 300 right?

and u can call on him anytime to rewrite?

wha t info does he use?

 

For the price of the custom eprom you could be burning thousands of your own. I don't understand how people get custom eproms made when the guy has never seen the car and has no logged data to work from! That's like telling a carb company what motor you've got and they pre-jet, adjust the idel screws, accel pump blah blah blah...you just don't do that.
Considering burning your own eproms is the same price as buying that ONE custom one...why WOULDN'T you do your own?

 

hmmm good point
but this is fuel injection
I actually DO plan on burning my own
just from what i heard about how easy can be

and i think most of u started out on here like me

not even knowing a posi is limited slip:lala:

 

I didn't know the difference between TPI and TBI from a carb! That was only 5 years ago. My buddy Ethan got a 69 camaro and I got rid of mye 86 for my 91. That's about when we both started getting HEAVY into cars and I started edjucating myself. Computers and cars have always been self taught, it just comes from time and focus.
Anybody can program eproms, anybody can get an eprom to work well with their car. That isn't what takes time. The time well spent is learning how and why things work the way they do. People say experience is the only way, I disagree. Experience is also learned from others and this board is loaded with experienced people. Hell, I explained a cam swap off the top of my head and I've had no experience doing the actual swap...yet .
Eprom burning is the best feeling in the world. Just like how you've got control of your vehicle with the steering and pedals, eprom burning gives you a deeper control. Now you tell the engine how to react to YOU, not you adapting to the engine.
Of course some things never change like the way a huge cam runs, but I can honestly say that the best money I've EVER spent was on the eprom burning equipment. Then the 2nd best time ever spent was learning how everything works (never stop learning). 2nd best...? yeah, guess what is number 1 priority. Hint: it isn't school

 

Yeah Jon, your kind of right and you kind of aren't. Unfortunatly, with such things as burning a chip, there are a lot of bad things that can go wrong if you don't burn it right, the same as if you throw an engine together without knowing what your doing, your probably wasting a ton of cash. Furthermore, I've asked countless times for help and explanations on thirdgen and have been told to either look at another website or to "do a search." Nothing frustrates someone more when your trying to decide if you want to get into something and your only source for help says to look elsewhere. I even posted my winALDL files and besides JoBy no one responded except to tell me to take it somewhere else...

If you can find someone who has knowledge of the stuff, and is willing to explain everything to me like a fourth grader, I'm willing to learn. I'll even spend the $300 for equipment and try a few curves. But with the attitude on the board of "if you don't know, your dumb" it gets frustrating...

Yeah, of course it's frustrating at times. Pablo helped me get into eprom burning. He answered my stupid questions and then he left for the military. After just sitting down and reading the informative reports/projects over at www.diy-efi.org it became clear. Then if you go and do a search for anything and everything over on the diy-eprom board you'll find not only the answer to your questions but also other answers on questions you never would have thought to ask. It took me a couple months to get that handle of the burning process but after doing searchs and reading posts about my topic of interest I got all my info and then some.
Right now I'll have more time to answer peoples questions since I'm done with finals. I had to buckle down this quarter to get the marks I wanted but I always reply to e-mails.

 

i think aslo keeping a stock chip around is also a good idea
so if something goes wrong u can just plop that back in

and start from there again

im definately gonna check out that link even if im not at that stage yet

and i know people do th is bu it seems like many dont

but whenever i have quetion i try to search the boards to see if its already been answered first


isnt it also frustrating as nice as it is know ing more than the average bear
and then trying to talk to someone who doesnt know and is filled with all the automotive myths and thinks your trying to be a know it all?

i wish i could touch someone and fill them with what i know and vice versa(ever see x-men?)hehe

kudos to the TOTW idea


maybe in 20 yrs people will be buying 3rd gens instead of FOX bodys and 4bangers for MODDER material.NAHHHHH

 

ok, thats cool, I'll give it a shot.

Not to get too far off topic, but does anyone know where we can get some of the prom burning equipment cheap? DIY-EFI maybe??
