Eventually I am going to have to step up to the plate and purchase a new crate engine for my '84 automatic. I'd like to get one from GM with the warranty. I just may not want to pay the price.

Anybody???

You could save buckets of money if you build one yourself. A huge portion of a rebuild is labor.

Why not rebuild your engine? You could easily increase the compression to 10, replace the camshaft and lifters with something slightly larger and enjoy life with a big smile. You could do this potentially for less than you would pay for a new engine. You already have forged pistons so you may be able to reuse them, recondition the rods, new gaskets, new bearings and rings if all is well internally. Good luck either way you decide!

Nitroussam,

In the first place I have no where to work on rebuilding my engine, secondly I would get it apart and forget how to put it back together, thirdly I am not that mechanicaly inclined and fourthly it is my daily driver and I can't afford to have it down for any real length of time, and fifthly (is that a word?) I don't have the time as I still work.

Thanks for the thought though. Anything helps at this point.

Regards,

Valkryder

Sounds like a bolt in engine is going to be the way to go for you. It is unfortunate that you are in such a crunch to get it back up and running so quickly because there are some very basic improvements you could make to your existing combination and make it a little more spunky for very little money.

The good news is that whatever you purchase has the same ability with a little planning. I would select an engine that already has 10 to 1 if at all possible and if the engine you are buying has aluminum heads you may try for slightly more like 10.2 to 10.5 compression. The benefit with more compression is more power instantly...the trade off is you will want to run better pump gas but that is a small price to pay for some added performance. You can also spunk up the camshaft in your new engine so that won't be an issue...you won't have to do it yourself, you can have the shop doing the install do it for you. Stay on the small and conservative side if it is your daily driver but you can add some performance very cost effectively. Best of luck to you.

another thing to think about is updating your car a little bit.
for instance, I have a complete firewall forward car wiring harness. It includes air conditioning, lights, alternator, etc.
you could upgrade your car to TPI with a wire harness, and get buckets more torque, increase reliability, and like your car a lot more.
I also have an extra TPI to go with it.
oh, and a 86 corvette engine too.

just food for thought

thats a whole other discussion. Not worth it.

I said it on the general forum and will say it again. The best bet might be to just get a inexpensive crate 290 hp engine and have someone put it in if you don't want to do it yourself.

I agree with that. I am working on a swap in my 86 T/A from a carb to a TBI and the wiring was a nightmare. i got it done but it was a huge PITA. And Ive been working on it for many many months.

I had to pull the ENTIRE interior out, all wiring in order to modify and hours and hours of reading 2 shop manuals to figure out what is what. My T/a runs now but it is far from done.

I understood that a 290 as a problem with passing CA smog. I really don't know what other options there are out there that will fit my car. If I get a crate to replace the one I have now will it come with the cross fire? If not, how does the computer accept a different induction system?

You will reuse your "crossfire" intake,exhaust manifolds,air-pump etc. I'm not sure about passing the smog tests of CA. (I'm in NY). You can check out SDPC website,summit racing,jegs for engines.

Most crate engines come less the induction system. The 290 HP, GM Goodwrench, LM1, engine is the closest thing GM offers for your car. You would install your existing Crossfire induction system into the new engine. Your existing ECM would operate it perfectly, and assuming everything is in order at this time, you should have no trouble with passing a smog test.

RACE ON!!!
