should be pretty easy.  If the car is an automatic...you are probably going to want to pick up a lockup switch for the converter since that is normally controlled by the computer...and without the TPI I'm not sure how well it would work...I would recommend against the TCI one...I have it for my 200-4R and its the biggest pain...keeps it locked too long, and wont stay locked on the highway.

my bad i ment to mention i will throw in a th 350 with the 383.  other than that though can you imagine any snafus? or is it pretty much straight foward  ie wiring harness or the fuel system? and will the efi fuel system work with a carb or sholud i just rerun a new one? by the way are their any trouble areas i should look for on this car before i buy it?

The TPI runs a way too high fuel pressure. I don't think a fuel pressure regulator could down the pressure enough (40psi to 5-10psi). Plus I think the TPI has a return fuel line.  The best thing to do is try and find a fuel pick up unit for your tank with out a fuel pump.  The cheapest thing to do would be to leave the electric fuel pump in place and just unplug it and hope a mechanical pump can pull through it.  My experience is that they can, but I haven't seen any long term application setup like this so I don't know if the mechanical pump will prematurely fail or if it will cause the engine to starve for fuel during long periods of WOT.

People, you see whats happening here? Its end of story becuase he cant think outside the 4" plus bore box because his ill fated attempt of applying 4" plus bore hop up techniques didnt work on the sub 4" bore engine. Thats why its end of story, end of discussion per JC.


Lets put a survey up: Is 300-340HP a decent power output for a daily street driven vehicle?


A. Yes it is


B. I dont drive in anything less than 500HP


If you answer A. Yes it is then check out this easy build for a person who thinks outside of the box: http://www.goingfaster.com/spo/343hp305.html

i didnt end any discussion i just asked about the z28 cuz it has a 305 and was already refrenced in this post. yes i want to yank the 305 asap simply cuz i KNOW for a fact the 383 will be able to make more power then the 305 could plus i have most of the parts for the stroker laying around from my dads project before he built a 427 stroker 400.if you want to hot rod a 305 by all means go ahead who am i to judge and like some one said earlier they are great beginner motors just fast enuf to be fun but slow enuf not to kill your self.   btw i also found out they really dont respond to mods in a 3rd gen f body at all so you are not alone(thats why zacks firechicken has a 383 thats FUN AS HELL) maybe im lazy but i want easy cheap and NOTICEABLE results not a bunch of smoke and noise that should have been results

LOL!  For some reason "Mopar man" just doesn't understand small-block Chevys!


Mopar Man:  Yup.  There's something magical about a 4" bore on a "shiby" small-block.  If you'd build one, you would realize why one will piss all over your beloved Mopar 383ci. 


I wonder why you talk 'smack' on the small-block Chevy, when you've never built one.  Sheesh!!

Ummm...the article referenced had an aftermarket rotating assembly, 10.26:1 compression, larger valves, Keith Black pistons, a high performance cam installed, an intake that is not smog legal AND won't fit under the hood of a 3rd gen camaro...not an option here, and was done on a dyno probably without any accesories, smog equipment, or full exhaust behind it.  Not a realistic test at all.  Its not smog legal...which is kinda important in my particular case since the car is an 88.

Not to mention I said that they could be BUILT to make 400HP.  They don't respond to BOLT ON's.  A rotating assembly is not a bolt on.

If they really wanted to do it right they would have ponied up for a set of World Products S/R Torkers for a 305.  They are only like 700 or 800 bucks and will outflow anything the factory put out.  Or a set of vortec heads...but then you have to get the more expensive intake manifold...

Please tell me how any of my performance upgrades were 4" plus bore specific?  New exhaust...CC recommended doing that...pretty sure any magazine that has done a 305 build on a thirdgen camaro has done that.  The headers are 5/8" primaries...not 3/4" or bigger.  Upping the fuel pressure...thats a little TPI trick that everyone does (regardless of size) along with bumping up the timing.  Milling the heads for more compression...The Otto cycle applies to any bore you like.  I'm pretty sure valvejobs increase the flow around any sized valve you like...and matching the intake to the heads works on just about any engine you like.  When I installed injectors I went with the 19 lb/hrs because that is what Accel (and everyone else) recommends for 305's.  I didn't go with a super ram, a stealth ram, or any other ram that intake companies have come out with for 350 TPI's because the 305 doesn't make enough torque...and will be a pig to drive around town because of the loss of low RPM torque (straight from the manufacturers who engineered the intakes).  I did NOTHING that was specific to big bores.  I'm really curious...if thats all big bore stuff...then how do you build a little bore motor?

I don't defend these engines...if someone wants to build one, I do what you did...I find an article to show them what they can do.  But if I had it to do over again...I still would have done the Borla exhaust (at the time it was $570 for the system...now its over $800...but it sounds a million times better than my friend's 350 with Flowmasters)...but the rest of that money would have gone into a 350.

I'm off to finish up putting together my Big Block Olds...which really makes any talk of torque and small blocks hilarious...let me know about those mistakes I made with the small bore thing.

Like TheSilverBuick said (I forgot) the fuel pressure will be too high.  You will probably want to look into a regulator...but you might end up having to replace that fuel pump with a lower pressure one.

The TH350 has been swapped in many times...you might have to move the crossmember, rebend the cooler lines, and adjust the size of your driveshaft...but that would all be worst case senario.

Converting to a carb has been done many times...I haven't done it, but can't imagine it to be very difficult...

I've seen them run decent times before...most I've seen are either using a large shot of nitrous, or a blower of some kind...but its not that its impossible...it just requires someone to build the hell out of it.  Gutting it certainly helps though.

Yep, when all else fails attack the author by assuming and then bring up the classic sbchevy is king of the crap pile argument because you know a sbchevy wins every time when your racing opinions. LOL, this coming out of the mouths of people who love a POS that has had every single part on it re engineered by the aftermarket. Your right about one thing, the piss part, but then again that's usually at the starting line because while your beloved heap is pissing green our Mopars are setting records still to this day. Blow your smack out your exhaust hole man!

You do realize that the small-block Chevy has been in the winner's circle more than any other engine on this planet.

Hmm, mostly 3 and 4 letter words, two of which can not be posted on this wonderful topic. I didnt know shrunken heads still existed these days. I suppose this is what happens when a shivy dork cant discuss or debate a topic especially when the facts are stacked against them. Just stop it man, I cant stand to lose. Go look at the super stock records and find a corner to cry in, I'm sure you mommy will bring you some milk and cookies. Shivy logic, when we cant win start bashing brands. That works every time.


It may take a little more thought to get a 305 to run but it certainly wont get their with your logic nova.
