heres the thing, it must be 10 years now i ve owned my 89 iroc, for the past 28 months it has sat out in front of my house because my fuel pump went, and i couldnt justify spending 1000+ to fix a 17 dollar part. any how, just week, through conversation meet this guy whos going to cut out a piece of my trunk floor pan and do the job for 200$ so im getting it done. the guy works at a restoration and speed shop, and it has gotten me all wet. i think i want the whole thing redone. heres my question, the entire time i ve owned the car, when something broke i replaced it with a high performance part. yes i did it for the power gains, but more for the quality of the pieces as far as longevity. i.e. msd ignition stuff, slp everything, a few tpis things, richmond gears, carbonfiber driveshaft and so on. i have never given any though to the internals. ever. im going to have the engine rebuilt, though i know nothing about crank shafts pistons cams roillors lifters (i do have a set of heads lined up. keeping in m,ind lonbgevity and "QUALITY" oh yea lightwieght, what brands would work best, see great resolts and, not break once its been on the road a few miles.
can i stroke it out or bore it out? if so where can i find more information about that?
i have a 305- some it seems on this sight dont like my 305 but no i am not going to swap it for a 572 crate or the new ls7, i want to stay true the soul of my iroc, i know i wont be the fastest, i dont want to be. i want some get up and go, a great sound some fun times tooling around, and some tire squeeks. but have a car thats going to last another 20 years to give to my son.
looking foward to some great feedback.

 

you can rebuild your 305, stock style rebuild, but based on what you mentioned, I don't think you'd want to do that (if you have a carbon fibre driveshaft...).

A 350 rebuildable core (nothing too outlandish), should be very cheap, lets say $100. The parts that are specific to a 305 (pistons and rings basically, crank if it's needed), are MORE expensive then 350 parts, due to lack of popularity. So if you were to spend $50 more on parts for your 305, when you could have saved that $50, and spent $100 for a 350 block instead.... well, in the end you could have spent $50 to gain 45 cubes, which is pretty cheap HP/$ right there.

I'd phone up your local high performance engine builder. You can either get a "hot street" 350 built, or buy a crate motor, with upgraded induction. You won't set any land speed records, but the 100' black streaks from your driveway will keep you smiling.

 

There are plenty of resources here on what can be done to improve the 305. Look around, you are sure to find something that piques your interest. There will always be people along the way that will simply say "Just drop in a 350." I understand that's not what you are looking for. I'm the same way.

 

yea, bolt ons work fine with a 305, but if your compression is bad (rings) and the motor is leaking and burning oil rather fast, then it's not worth the effort to re-do a 305 core. If you want reliability, then you're probably re-doing the entire motor, so might as well start with a better platform.

Lets not get into that discussion though, it's been done at naseum.

If you want to stick with your 305, ok, we can help you out, if you want to go to a 350, fine, same deal. If you're not sure, then do a search, but don't fan the flames of the 305 vs 350 debate.

 

i dont want to even metion the 350, i ve read a few of the topics already, and do not want any part of that debate. i ve have given thought to droping in a 350 because it would simnplify the whole thing, but if i do that i then go down the road of well why not 454 or a 502, hell let me bore out and strojke that 502, etc. ive made a comitment to my car and to its original 305. before it statred its 2 year nap, it ran fine did not burn any oil as far as i could tell, no smoke out the back, no strange nosies, nothing. i ve spent a few hours today finding makers of cranks and pistons, etc, i have only found steel cranks, are there cranks made out of titanium? or another stronger/ lighter alloy or metal? the same with the pistons? can anyone tell me about callies cranks? and there dragon slayer? i sment a goodf deal of time on the gm parts websight and cant seem to find much of anything, are there web sights that have a ton of info on these parts to help refine my ideas? are there links on third gen . org that have already delt with thises questions?

 

Why not just replace the fuel pump yourself? It's a cut & dry procedure, takes 8 hours (took me 8 on my first time), and a standard set of tools. The rear doesn't need dropped, just the exhaust (and we could get new hi flow muffler for the extra savings!). The pump costs $65 at Carquest. You'll save cutting into your "I want to keep it stock" body. You need a jack, two jack stands, and a normal range of sockets and wrenches. Search my posts - I wrote it all out about 5 months ago. It's really easy, just time consuming.

 

titanium crank? never heard of it myself, but why not eh?

callies? ok ok, how much do you plan on spending on the motor? set on the 305 then? Just want to make sure I understand you right here.

 

as far as the fuel pump- no one i spoke to said it was possible. two years ago i went to every speed shop, gm parts shop and a few local motor heads. so based on that i took it as fact. i will check out your post though.
as far as a budget. none really- what ever it takes to get the job done the right way. money is always a consideration, however with what i do, theres always a nice flow of cash around.. well at least stating april 15th, lol thats when my tog season starts! waiting all winter for this. togther with no real time frame, the budget isnt really a budget. i know im not planning on spending ten grand or anything. i guess throw in a paint job some tranny work, a new rear. i have 3:73, got them 6 years ago after trying to hotdog around a few red lights. im having a difficult time finding anything higher then4:56 i was hoping for a 5:10 or 5:23. i wont be doing highway driving at all, looking around 5 - 6 thousand i guess.

 

Well - there are many of us on here that have replaced fuel pumps - anyone that tells you it can't be replaced is a total idiot. It's not a 10 minute job for anyone, you have to drop the exhaust and the gas tank to do it, but it's not impossible or even hard, just time consuming. I did mine on my own in my 1990, with no one to help, and having never done it before - it only took me 1 day (8 hours), and at least 3 of those hours were spent with trips to the parts store.

Questions about your car - ask us here on TGO: we are the people that work on them every day - leave those other "speed shop, GM parts dept, and motor heads" in their own stupidity - unless your talking to a thirdgen person, everyone else is in their own little ignorant bliss (as we are probably in ours here LOL).
