Mack, I had a 327 build for me over 10 years ago. If I had it to do over I would build the same 327. What 327 do you have? What do you want it to do? What Tranny? What rear gear? The 327 likes RPM. Bob J.

I've rebuilt mine twice. Why not outline what questions you have and we can go from there.

I'd say that you'll find quite a few people who have built 327's here.I've done two and have one in the planning stage.

Have built many. Just remember they don't have as much torque as the larger engines and like a lot less cam and cylinder head.

Hey guys, the 327 is a 64 small journal 250 hp version. I'm trying to figure out if the 327 would be wise to build for my 3800 lb. wagon. It would be a daily driver. I have 308 rear gears and plan to leave it that way. I currently have the crappy powerglide but am planning on a t56 or tremec 3550 or tko swap for the overdrive. I currently get 10 mpg which I think is terrible but havent got anything to compare it to. I put headers and flowmaster exhaust on it, it sounds great, I would hate myself if I put in something that didnt sound as healthy as a basically stock 327. At this point I dont know if I should go the 383 way for the torque I need or what would be wise. I will be taking it to the local 1320 on the weekends so I need something respectable. Any suggestions on maybe if I should go with another engine? Hopefully someone has built a 327 and 383 or 400 and can compare them for me.
Thanks for your input,
Mack

Well, if you are concerned with a 327 having enough grunt for a 3,800 lb wagon, why don't you just drop in a 3.75" crank and overbore .030 for 383 cubes?

I rebuilt my 327 for a 68 camaro and it ran great. It had 11:1's, comp cams 268, edelbrock performer and holly 750. Not much for gas mileage but it's fun to drive and scares the krap out of rice burners.

Any sugestions, I'd say use a Rochester quad jet for gas mileage and get rid of the powerglide. I garuntee, you change the powerglide for a TH350/mild torque converter/shift kit and you will feel a world of difference.

I would go with the 327 because you already have it, and it was available on the 64 Chevelle.

I built my DSE 327 to replace my 283 with 'glide. Like yours, it is a 1964 block,forged steel crank. Had it balanced, bored .030", crank polished.
Bought:

-Crane Energizer cam (.454" 216 Deg duration @.050"),
-Trick Flow heads,
-Quadrajet carb,
-Performer intake,
-Coan 2600-2800 stall converter.

Like you, I have 3.08:1 rear gears. Engine has plenty of torque & I'm getting 17 mpg's driving back and forth to work!

I have a balanced 327, .030 over in a '70 Nova (Chevelle's little brother) with 461 heads, 1.94 intakes, 3 angle valve job, TRW forged small dome pistons, Performer RPM, 650 Holley Spreadbore dp, recurved points dist, Comp Cams XE 262 (lift .460-.469, duration 218/224 @ .050), headers, 4 speed Saginaw (3.11, 2.20, 1.47, 1) and a 3.08 open rear end.

Definately not a race car but does accelerate well in 1st & 2nd gear and I get 21+ mpg on the highway as long as I keep my foot out of it. Since my CR is about 11:1, I usually run Amoco 93 octane. Hope this helps.

I stroked mine to a 355 w/461 heads and a z/28 style intake. Be conservative on your cam and I think you'll be happy.

The 250HP is a very efficient motor with the small carb and heads. The only thing I would change would be to use a Qjet(a definate improvement on what you have) Just build the rest pretty much stock and loose the glide.

Now we need to get an idea of your budget. We love to spend the other guy's money. I think the most cost effecitve thing you can do is rebuild the 327 with a live cam and TH350 Trans. You need a first gear to let any 327 to come alive. Then maby you want to build something like a 427 small block, 700-4R, T-56? Now we might want to beef up the rear end a little. http://www.chevelles.com/forum/smile.gif That 250hp 327 is a great all around engine that can give you lots of fun driving and save you some money for other fun things.

Hey thanks for the replies. I'm trying to keep it under 4k for the engine budget. I'm also debating between the t56 or tko/3550 swap. I am definatly going with a manual with overdrive Which do you guys think is better and easier to put in.

Hey guys ive decided to go with the 327/ tko 5 speed, any suggestions on building the engine?

The 250hp/327 had the small valve "power Pak" heads, I think you could find some 194/150 heads that will work well on the 327 without going over budget. The L79 cam is a proven cam for the 327, Runs good, Good sound and you can keep the compression to 10 to 1 and still run pumped gas. There is better cams, I used the L79 because it is long proven in the 327. JMOP Bob J.

I'd recommend you dump the stock heads, they need hard seats, guides, valves, etc, better off to buy a set of cast iron replacement Torquer S/R's or some other modern replacment heads. Even Vortecs will work, but you'll have to buy the right manifold. rebuild the shortblock more or less stock, use a UD or Crane short hydraulic cam like 268 or so, decent timing chain, performer manifold and Q-jet carb, get an HEI for ZZ4, set of quality headers. You'll have money left over from your 4G.

Hey guys, is the vortec heads a good choice? I have heard nothing but good things about these heads and wanted your opinion on them. Tom, I am located in Sedgwick, Kansas, about 20 miles from wichita.
Thanks,

My buddy has a 67 Malibu with a small journal 327, port matched camel hump heads, xe268 cam, 3.36 rear (i think), performer rpm manifold, q-jet, and a 200-4r tranny with a 2400 converter. That car is driven every day for long distances (to see his woman), goes to 6000 RPM, and gets over 20 mpg. That short stroked engine is great for a long life daily driver.

Unless you're planning on building a racer, you can build a 327 for way under 4k. I saved a little money on mine by assembling it myself. Total cost was around $2500.


.030 overbore, .010/.010 on the crank, decked and align bored
10:1 C/R pistons
Balanced rotating assembly
reworked camel hump heads (hardended valve seats, heavy duty springs, nickel valve guides, stainless exhaust valves)
I went with a seldom heard-of cam in the Elgin Pro Stock
.442/.442 214 dur @ .050.
1.6:1 roller rockers

I have about 500 miles on it so far. I'm looking forward to getting my car out of the body shop so I can put some real miles on it.

Tim,

I bet that little 214 cam really gets the 327's midrange up and really helps it scoot down the road with about 10 to 1 CR. if it doesn't detonate..

I say this b/c the old -151 cam really likes upwards to 11 to 1 CR. to really run great in the little motor..pdq67

Mack,

The Vortecs are wonderful. I've got my fourth mill going together with them. 400 h.p. is no sweat whatsoever, and you can see 500lbs ft of torque in a SBC 400.

A Vortec 377 (destroked 400) I built, is now tearing up the oval track here; and I dropped a 355 in the 5,000 lb tow rig..... plenty of torque, and 13 MPG.

Hey jeff I'm not sure at this point. My dad had a machine shop prepare his olds 455 and I will probably go with that same machine shop. I will get the name and let you know.
