#'s matching 327 Rebuild

I have a few questions regarding the rebuild of my 327. This is my first engine rebuild, so a lot of these questions may be simple.

Im rebuilding my 327 to put back in my 68 chevelle. I plan for it to be kickin high performance motor without taking away the fact that it is numbers matching.

1. Can i replace everything but the block itself?
2. Can i bore the block without ruining the fact that it is "numbers matching"?
3. Is there a certain bore that i should go?
4. Can i run aluminum heads on the stock cast block?
5. Since i plan to completely overhaul the engine, i can replace absolutely everything not including the block itself?
6. Can someone give me a road map to rebuilding it?

Re: #'s matching 327 Rebuild

IMO,You can do what you want to be satisified.It's your car to have and enjoy.On the other hand,if you plan on selling the car sometime down the road,Clean and Keep all the original parts and store them wrapped and boxed in a temp controlled place.For the most part people tend to be more intrested and pay more for cars with correct componets to switch it all back if they choose to.

Re: #'s matching 327 Rebuild

If you are looking to drive the chevelle, store the 327, Get a crate engine, install and drive. That way you have all the numbers components safely stored if you would like to put it back or sell it one day. You don`t have to worry about ruining the original engine.

Re: #'s matching 327 Rebuild

Wes-- Going through the same thinking now with my '65... 6 years ago I took the (fairly gutless) #'s matching 283 out of the car, put in a .060 over 327 with the double humps, RV cam, edelbrock intake. Running great ever since, had a ball doing my first rebuild & swap, etc. A month ago, I was puttering around in the shed attached to my garage and I started looking at the old 283 on the floor, thinking things over. Next thing I knew it was on the stand, to the machine shop, now back on the stand, mostly put back together. I'll swap after the summer driving season is through. I went .030 over, .010 under on the crank. Since it's a driver, the old powerpack heads are still sitting out in favor of some 305 heads, bigger valves, high enough compression... Bottom line, I consider the motor to be #'s matching and will have fun driving it. I imagine in a couple of years I'll take the 283 out, cam the hell out of the 327 and swap them back again. It's a hobby for me.

In answer to your questions about parts, if you want to get your hands dirty rebuilding (I know I do) and don't want to crate 350 route (cheaper and easier and more freakin' cubes...)

Get an edelbrock top end kit- Good value, they did the math for you, good aluminum heads... The HP numbers are for a 350 so you'll have a little more bump with the 327, though less HP... Do some cam research and get the 600 CFM carb. It'll really go. 327's are AWESOME... Go to .030 over, save the .060 for the next time... Keep the same crank in it, save everything else, no matter how trivial it seems. Let us know what you decide and how it's going.... ---Rich

Re: #'s matching 327 Rebuild

Or check out the MANY, MANY 383 rotating assemblies out there now along w/ at least a set of worked over double-hump heads!

180 to 195 big valve aftermarket heads would be better tho.

Re: #'s matching 327 Rebuild

All great thoughts. Thanks a bunch. Ill contemplate it (crate or restore).

If i do go the crate route, would it be advised to hot tank the 327, get it all cleaned up, then store it. At this point, it sat in the car since 1968, use your imagination as to how amazingly dirty it is . Whats the best way to clean the whole block while at home. Ive heard a lot of people saying that water is bad, and others saying go ahead with it. Is there a special solution that makes things easier? Everyones opinion would be great.

Thanks again,
Wes

Re: #'s matching 327 Rebuild

If you're not going to rebuild the 327, don't open it up. (Still sounds like you want to get your hands dirty...) If you save it to sell it later on, the next guy will want to build it. If you want to build it later, you'll end up doing it all over again anyway.

I'd say go for the build yourself right now. It's great to know just what you're driving around that you made it yourself.....

Re: #'s matching 327 Rebuild

the key to rebuilding an engine like that is to avoid decking the block, milling the deck surface. that cuts the stamped numbers off. If the deck is not warped or damaged don't deck it.

better to just set it back somewhere. get it out, pull the plugs, squirt oil in the cylinders, use a roll of saran wrap and an engine or large garbage bag, seal it up. Later it'll be available if you want it.

I wouldn't try an NOM deal for a first or second or third rebuild. Too many ways to get had.

Re: #'s matching 327 Rebuild

What my plans were, is to very slowly rebuild this engine. Im a broke college student who would only put money in it, when i had it. Decking isnt the same as hot tanking it right?

Well i guess i could explain my situtaion a little bit more. I pulled this motor over a year ago and put a little 283 high performance motor. I havent touched the 327 since. I dont know if that changes your outlook on what i should do.

I am very confused

Shed your confusion; read a good book:

Re: #'s matching 327 Rebuild

2 x the David Vizard book. All you need to know... But don't open that 327 up and start the work unless you can do it all. Cast iron will rust fast, then you'll do it all again...

Re: #'s matching 327 Rebuild

My approach would be to buy a book and do your homework...before you start the rebuild...
