Robert, the intake mod is a piece of cake. I did mine with a Dremel. The difference is that the 4 center bolts on your heads now are made to go in almost vertical. On the older style heads they are angled. Once I ground out the holes in the intake , I cut some small pipe to match the angle or the intake and the installed the bolts. It sounds harder that it really is. So one tool you'll need it a Dremel. The flex plate is also easy. There's 6 bolts that attach it to the end of the crank. Just order one from Summit or Jeggs. There's no internal work involved. You've already mentioned getting a torque wrench so let's get this baby going. No fear. Also, I bought the wiper arms from G-boz. He's shipping today. As soon as they arrive I'll send the same box to you with the drivers side arm still in it. Thanks..

Thanks I was freaking last night after all the questions asked before buying the motor the all of a sudden nothing was going to fit. I can see the light again after a couple hrs. of sleep and make this project an all new acc.'s for the motor and take my time till the 305 dies or who knows maybe me first the way it's running now it could go another 300k easy. My compression is correct and when I pull the plugs they always look like the should no oil or build up on the tips just look like they been used.

My 305 motor is coming out tomorrow and a beast of a built 350 going in. A reputable mechanic re-built my 350 motor for $1000.00. The motor itself cost me $100.00! Has large 2.02 intake and 1.60 exhaust vavles! Mild cam and edelbrock intake. I am keeping the carb and exhaust manifolds. Should be a awesome!
Robert, I will have you come check it out. Should be done by Friday.

If you can squeeze your way into the engine compartment, a photo of two of the four center bolts (either side will do) on your intake will answer a lot of questions.

Also, a reading of all the numbers on the right cylinder back of the block, just in front of the right hand head, will tell us a lot.

What I'm trying to determine here is if, in fact, you have Vortec heads. If you do, the extra $500 for the Vortec engine would be money well spent.

There's pic's on page one with the numbers but not off the block. It's the standard 1987 305 I bought the truck new in 1988 but it's an 87 FOR SURE they didn't make 88's I don't want to start that issue again.oke:

If the intake and flexplate are what is standing in your way.... I have both from a 85, 305, yes they will fit and the intake is a original factory aluminum smog legal. These will both fit with no mods. Fifty bucks and they are yours. PM me if interested.

 

[chevcamino]

The flex plate should be fine. I installed the crate 350/330hp on an 85, direct fit for everything,install went smooth as silk.

 

[Bobby78]

One last time...the 350/260HP and the 350/290HP ARE THE SAME PRE-85 ENGINES with different cams! You ARE NOT getting VORTEC heads for the extra $500 as was previously mentioned.

That being said it's not that big of a deal to swap out your 305 for either one. Not sure what exhaust manifold you have on the passenger side. Mine has a short spacer with a heat riser (butterfly) valve and then the exhaust mounts to that. I had no problem installing it with my 350.
The 305 and 350 are the same externally. The differences are only internal. Get an engine stand or rent one. They're cheap new. Less than $150 and if you keep it clean sell it after. Install everything you can on the new engine while it's out of the car. Install your old oil pan in place of the new one because your dipstick won't fit the universal either side pan that comes with the new engine. So add oil pan gaskets to the list. Install the fuel pump, water pump, intake, exhaust manifolds, power steering pump, A.I.R. pump (if you have one) alternator, etc. You can leave the fan off. It's not that hard to install in the car and it will give some extra clearance. Plus you don't have worry about bending it if it hits something on the way in.

I tried to cancel the motor last night but it looks like it maybe coming and that's fine so let me see tonight and if it shipped I will buy yours for sure. I will let you know tonight if it shipped.

O.k. That's the info I needed. already have a lead on the intake and flex plate so next is seeing if nit shipped or canceled. I called late last night and all they could do was pass the message but it shows in process so i'm letting it ride and should know tonight.
Thanks again Bobby simple and to the point.:beer:

One other thing should I start spraying the bolts now or wait till a couple days before trying to loosen them?

 

[JJLT1]

what i was refering to for $500 more was the 96-up truck motor,, 4 bolt,, vortec head,, roller cam,, rated 255 hp IIRC..
http://paceperformance.com/i-648492...0-gvw-96-00-ck23-g-l31-99-p3-5-7r-cpi-hd.html

and the oil pan will not fit/swap over to the 2 motors in the links..:texas:

 

[EdontheBeach]

1- like bobby78 said, they are the same engine with different cams and neither are vortec
2- be aware that GM will tell you they are 8.5 to 1 compression, they are ACTUALLY 7.9:1 - i burp more compression than that.

i have the 260hp in my car - installed it in time for 2011 power tour - it runs nice and smooth; never had even a hiccup BUT i'll be pulling that motor and installing 64cc heads to bring the compression up to 9.1 : 1, which will get the power up a bit and still use 87 octane gas.

my 2 cents is you will be money ahead getting the truck motor mentioned by jjlt1 (you'll need elect fuel pump for it)

 

[HKDUP87]

O.K. I got the other motor canceled and this is what's recommend by JJLT1
jUST WANT TO MAKE SURE THIS IS THE WAY TO GO. For $500.00 more it has the balancer and will I be able to use my intake manifold and exhaust manifolds correct? If so in the long run this would probably be the same price as the 350/260hp after the extra parts that won't fit and need to be replaced correct and should be a bit easier for me to work with I would think except for the fuel pump. IS THERE SOMETHING I SHOULD KNOW BEFORE I PLACE AN ORDER FOR THIS. I need input on any problems that may need looking at before I end up with a motor that's going to be my new display in my growing parts dept. in the extra bedroom.

Hey Robert, i got the bezels and other items last night. Thanks for the extras.. The bezels are going on today at lunch. As for the engine swap.. is your transmission able to take the extra power? Not sure if you've ever replaced it. When I bought my Monster 200-4r, I got the one rated for up to 400hp and then added ad few other goodies since I pull a trailer alot. Just wondering.:texas:

 

[horseman]

Robert
I believe two things on this.
1. The engine is a great choice and Jegs is a reliable company
2. There is no such thing as the guaranteed "nothing else needed" you are looking for.

There WILL BE somethings that come up during the swap. Following the path you are by asking all the questions up front will certainly limit them and is a great plan. But doing the swap is also a great deal of FUN ! (although sometimes not while in the midst of itoke and will give loads of satisfaction from a job well done. Why else do you have a personalized hot rod cruck???

Jump in with both feet and lets get-r-done!!! All the guys here will follow along and give all the guidance and help you need. Its gonna be a great time.

 

[EdontheBeach]

IMO this is the better way to go - you not only get the votec heads you want and the balancer but you also get the roller cam. i was a hairs breadth from buying this motor but i didn't want the centerbolt valve covers nor did i want to use an electric fuel pump ....now, with 20/20 hindsight it turns out to be the motor i should've ordered.

i am about to spend $1,000 to get 64cc heads on my current engine so i can still use the new intake manifold i bought with the engine, the new valve covers i bought and retain the mechanical fuel pump and i STILL will not have a roller cam, nor can i retrofit that block for a roller without buying very expensive lifters.

yeah, that's the one i would buy...

 

[fauxrs]

I'm not sure if I read that you were keeping your emissions controls or not? If so, you should know that the vortech heads dont have provision for the exhaust heat crossover, so if you have EGR controls mounted to your intake manifold they will NOT function. Later vehicles drew EGR gasses off the exhaust manifold.

I dont know what electric fuel pump you plan on using, some are so loud they are difficult to live with IMO, make sure to do a good job isolating the pump from the frame so vibration noise isnt introduced. Also make sure to get a quality pressure regulator. A regulator with a pressure guage is reccomended so you can be certain what pressure you are running at the carb.

I never punch it . I'm a daily driver kind of guy the 305 is all I need even a V6 wouldn't bother me. Your welcome hope the bezel's were to your liking they looked pretty clean. For the shirt that's advertising I'm nation wide and like to keep my name out there.

Horseman I know not everything is exact I just don't want any high dollar surprises like the last post for the 260 hp it started with a flex plate and that was fine then all of a sudden after I ordered it more issues popped up. I just want to know what to expect before ordering . I'm not a mechanic and this will all be new to me so I'm trying to do this right the first time and take my time.

This engine will have to pass smog for sure so this engine is not going to work?


NO DISRESPECT BUT CALIFORNIA SUCKS!!!!!!!!!! I SHOULD HAVE STAYED IN MONTANA





O.K. NOW I'm PISSED OFF NOT AT ANYBODY HERE THANKS FOR ALL THE HELP. I'm GOING TO START A NEW THREAD IN REGION 18
WHAT MOTOR CAN I BUY THAT WORKS IN CALIFORNIA AND GO FROM THERE OR I'M GOING TO GET STUCK WITH SOMETHING I CAN'T USE.
THANKS AGAIN AND I STILL NEED ALL YOUR INPUT IN THE NEW THREAD.:nanawrench:
