my mommy loves me, not the car. but she'll fix it.

That's right, mom was nice enough to say she'll put the money up for a brand new 2.8L v6. It's great. it'll be a little expensive, and she doesn't want to use my money up on it. so she'll pay the whole 1,975 bucks to get the bird back on the road. But hey, the motor comes with a 3 year warranty, plus 75,000 miles. And a new block, let's say goodbye to all those mustakes out there.

Why are you getting a 2.8L??? Why not get a 3.4L or something bigger? Anyways, where are you getting it from?

well, thought about a 3.4, but I think i'd need a new computer, and that'd be more money. So, I think we'll just stick with the 2.8L. It's coming from a place called Rhodes Engines here in St.Louis, the guys will get and install the engine in 3 days. Now, my shop could do it cheaper, and i could probably do it even cheaper, but the beauty is that if these guys screw up, they also pay up. anyway, i can't wait to feel the power, of a brand new block.

What a waste of 2 grand... when you could just as easily drop a carbed L98 in it.

Why not just add a new CRANE 2030 cam for 169.99 and some 1.52 rolelr tip lifters for 109.99 and get a lot better engine.

where's the love at blade? And I couldn't just as easily drop in a 350 TPI. Granted after everything was done, i'd have a lot more power, but it'd be cheaper just to go out and by a tuned port firebird/camaro. Now, dropping in a 350, would be a waste of my money, because the swap would cost hella more than the cars worth. This is a beautiful f-body to say the least, and my dad's the original owner. So a brand new 2.8L should be nice, and hell, it might even go longer than the old one did, that topped out at 233,000 miles. Now, just to finish off that 350 idea, these are the things i'd need to get.

A junker tuned port 350
have the engine checked out, possible rebuild nessecary
have the tranny pulled out, possible rebuild nessecary
Driveshaft pulled,
rearend pulled
switch from drums to that posi unit, TOMP, even said that was a slight b*tch.
and then gank the computer. All in all, i'd have to buy a crappy car, just to fix a nice one. So i think the 2 grand will just be a tad cheaper, plus it's done at a performance shop.

Why would you need a new computer? You'd be re-using the whole intake from the top of the 2.8, right? Congrats also on the purchase... you'll have to let us know how that bad boy flies after the new motor!

Hey ask them to do a compression test on the motor after they install it- I'm curious to know how my #'s rank with a brand new 2.8l

Tom, do you have a Hayne's manual? I think in the back it has the compression on the 2.8L. Well, at least the stock numbers. i'll dig it up in a little if you want it.

Oh, it's in the back? I always looked in the front, hehehe... they listed a compression # for the 4cyl, but none for the v6 or v8. I thought that was odd. Hey if you find 'em let me know!

here you go tom.
it's a 8.9:1 ratio which is the second lowest. The lowest one, is actually an LG4 with a 8.6:1 ratio. I'll have to see what the new one has. and then see if the guys can raise it

Oh, heh, I meant the compression numbers, as in what you read off of a compression gauge. That's measured in PSI... I had 5 cylinders between 140-160 PSI, and one lame duck cylinder at 130 PSI. I was wondering what your new engine could hold.. then I could see how "worn out" my motor really is.

The LG4 is only 8.6:1?! Wow, my friend has that motor in his '86 Monte Carlo. Hey, maybe I could beat him in a race!

sorry tom, thought you meant compression ratio. And you probably could beat your friends monte, before the old board went down, someone with a monte carlo SS, said that our 1/4 mile times were better than his were.

Tom, I went to the motor shop, and the guy told me that a new 2.8L, or atleast all the ones he's dealt with, normally run roughly at 180psi per cylinder. Just thought you'd like to know.

Hey, great, thanks buddy! Hm, looks like my numbers are kinda far off. Oh well, at least now I know! Thanks!

I'm not sure how accurate those are, and i'll probably buy a compression tester, and see for myself. I'm actually kinda curious now.and if it's runnin' low then i'll take it back to them and make them do it all over again. hehe. i love warranties.

before he gets the motor.....
can't he get a 3.4
it would bolt right in
he'd be able to use the existing MPFI setup
and he'd have more power?!?!?
right????
if i am wrong then sorry, but I think it would be smarter to put the 3.4 in it.
no other parts to pull. the computer would work fine.

alright slowcamaro, here's the jist of it. With the new Missouri regulations on Pollution and emesions, you can't have any motor, (newer or later) in your vehicle that wasn't available at the same year your car was produced. So, the only engine i can put in is a 2.8, unless i want to go down to a 2.5, or up to a 5.0TPI, TBI, or CFI. kinda sucks to live in Missouri huh.

What if the newer motor made less emissions than what was originally offered with the car? Same thing?

yeap, dumb *** hell huh, it's pretty sad. I've got a friend with a 82 Grand Prix, he knows that he can put a 305 in the engine bay because it'll fit, but the prob is that the largest engine offered on an 82 grand prix is the 4.1 with a 4 barral carb, just like he has now. So, my plan like many of my friends is to wait 5 years till my cars a classic, then i can drop in anything i want and they can't say crap.
