Re: 350 Small Block Carb or Timing Issues

that's why i said "a cheap 305" ,i dont know what part of the world you live in but a shitty swirlport 350 is $500/$800 here most of the time
and i have never witnessed anyone give a 305 away,that's why i grabbed that lb9 out of a 92 t/a,it was $300. i sold a couple parts
i didn't need off it for $200 so in the end ive got a replacement 305 lb9 for $100 with 100,000 km on it.it has a b.n alternator,starter etc
and has already saved me a bundle on buying parts here and there.

any vortec 350 truck motor around here is around $1000 and most of them are high mileage and boiled over/overheated/run into the ground or non vortec swirlport pos.
i dont know if you are aware of the phenomenon but geographically things arent the same price/availability everywhere.if you want to drive your car NOW and
can get a running,low mileage lb9 305 to tide you over for a couple hundred and and not wait until you can find the "ideal" engine.....i stand by what i said

the last thing this hobby needs is another third gen sitting on jack-stands ,or knee deep in grass rotting,hoodrats throwing rocks through the windows or stripping off parts to buy meth
while an owner gets more and more frustrated then the wife gets more and more bitchy and says "get rid of that "f^%king thing,it dont run anyway"
or the neighbors/city start complain.i know i cant have a non-running anything sitting in my driveway were i live.

i love the "dont bother with a 305 ,just put a 350 and if your doing that just put a 383 mantra" but it just isn't practical or doable in many cases especially
when a 305 is there already or available for the price of a used intake and capable of making decent power without a lot of issues and insane cost.
yes,i want a vortec 350 ,lt1 or ls but i dont have the financial means to do it(right now),neither do a lot of other people.i dream big but live practical.

Not a bad idea at all. I did just that when one of my 350's was in the machine shop. All of the bolt on parts swapped over: headers, intake and carb, accessories etc. I putted around with that until I had the fresh 355 shortblock re-assembled and had gathered up all of the new bits to go with it.
As has been suggested here, a 305 might come to you on the cheap because few people want them.

Re: 350 Small Block Carb or Timing Issues

DON'T put a 305 in your car. Cheeeeep, freeeee, even if somebody PAYS YOU to do it. It's a BACKWARDS move. It is A BAD IDEA in every way.

Doesn't matter how little the "305" costs. You will spend EXACTLY as much putting it in your car, as you will a 350. Fluids, belts, missing parts, might-as-wells, and so forth. EVERY DIME you put into a 305, cheeeep" or even "free", just moves you ONE DIME farther from what it is you REALLY want.

Learn to delay your instant gratification; set a goal; and FOCUS on it. (yes I have adult children)

DON'T put a 305 in your car.

Re: 350 Small Block Carb or Timing Issues


FINALLY got the stupid wheel locks off. Couldnt hammer a socket on so i had to cut i to them with an angle grinder, coat it in pb blaster, coat it in pb blaster, coat it in pb blaster again and then wedge a chisel in the slot and smack it with a 4 pound sledge. Holy crap that was the worst

Re: 350 Small Block Carb or Timing Issues

Those are pretty eeeeezy...

Just drill the studs out of em. If they're on they're that tight, odds are, you need new studs anyway; not really losing anything precious by erasing them. Start with a small bit in the center, like 1/8"; then 1/4"; keep getting larger until they fall off. Only takes acoupla minutes. ZERO risk of damaging the wheel.

Re: 350 Small Block Carb or Timing Issues

The wheels are already pretty banged up. Scratches and gouges all over, whoever owned this car before me didnt take the best care of it. Also, this 350 is officially dead. Pulled the pistons and crank out today and its just more bad news. When they out the pistons in the must have heated up the rods to make the hole bigger for the pin that connects the piston to the rod. Number 8 and 6 are a nice blue steel color and 6 takes a lot more force than there should be to rotate it. 8 rotates way better than any of the others weird enough so idk if they shaved the connecting rod down or what. A new rotating assembly is more than i can afford so im going to try and find a used 350 or try and pull one from a yard. Not sure if ill be able to find a decent one but ill try and keep you guys posted

Re: 350 Small Block Carb or Timing Issues

It looks like whoever assembled those pistons and rods used a oxy-acetylene torch IMPROPERLY, instead of the proper rod heater.

Re: 350 Small Block Carb or Timing Issues

Right: the rods have to be heated, to put the pin in; the small end is about .002" or so smaller than the pin, so the usual deal is to use dry ice on the pin and an induction heater on the rod; but it looks like somebody was real enthusiastic with a torch instead, but probably didn't freeze the pin and so had to excessively heat the rod. Or maybe just liked [beavis]fire[/beavis].

Some degree of variance in the pin fit in the pistons is normal. Usually if it's loose enough to move by hand at all, it'll loosen up and work fine in the motor once it's running.

Still, looks pretty ham-handed.

Re: 350 Small Block Carb or Timing Issues

Hi everyone. So my school term is almost over and ill be going back to work in January. I've been able to get a scholarship that will allow me to spend some extra money on the Trans Am.

Im going to be putting a crate engine in (probably from blueprint engines) that makes in the neighborhood of 400 HP and but on an edelbrock intake and probably a holley or brawler carb. Also, I may need to rebuild or buy a new trans because the one I have doesnt have a lot of backstory other than it was taken to a driveline shop and either rebuilt or built up. On top of that I'm most likely going to be putting a new rear end in also. Im not 100% sure what I want to do there though. I know I could probably find a used one for cheaper then a new one or fabricated rear end, but also having the convenience of a bolt in and knowing exactly whats in it and that everything is new and in working order is a big appeal to me.

Also a couple weird questions I have, do the third gens have a fan shroud stock? Mine didnt have one and a lot of radiators Im looking at online dont come with them so I was just wondering. Also, the trans mount quite literally does nothing to hold the trans in my car so who sells a replacement for those because the rubber part it sits on is split in two.

Im probably going to go with all new parts so I know what im getting is good and wont break even though it will cost more than used or rebuilt. I want this car to be fun but also reliable more than anything so that's why im going to be going with new parts. Im going to try to link as much as I can for what im considering buying but all feedback is appreciated. Also Im not sure what else would be a good idea to put in to car like subframe connectors for instance so anything structural that you guys can think of I would like to know because ive never taken on a project like this. Thanks guys

Do you realize your link is for a 4x4 transmission?

Re: 350 Small Block Carb or Timing Issues

My 2 cents, don't try to do all of this at once. It sounds great on paper, but what usually happens is LIFE gets in the way. It is much easier to take the car apart than put it back together. If you think you have every detail covered, you will find that there are hundreds of little things you forgot about, and it's those things that can add up to thousands of dollars more. Wait on the rear end until you have the engine and transmission working the way you want. Believe me, you WILL change your plan many times along the way.

Re: 350 Small Block Carb or Timing Issues

Yeah I suppose you're right. I'll start with the front end and work my waway back. It might just be a month or two till I can get the parts

Re: 350 Small Block Carb or Timing Issues

That is the torque arm.
Probably something worth replacing as you move forward.
There are several options regarding design. That is, adjustable or non-adjustable, forward mount on the transmission housing or a dedicated crossmember that divorces the arm from the trans, the type of front mount used (OEM style or rod end), short/long, colour, etc...
Plenty of threads here on the subject.
