Thread: 327 build up

Tweet

i read some of the the other post on the 327 but didnt want to take anything away from his post. im currently working a 61 nomad wagon and have a 327 for it. i stripped it all, and basically tossed everything, only thing there is the block and heads. i plan on driving it daily so im here to get suggestions. everyone has different tastes and philosophies, i just have no idea about motors. on the edelbrock page couldnt see the differences between the Torker II and Perfomer packages except the RPM ranges. im really naive when it comes to motors. want something fast but that is not going to overheat. things i wanted to run on the motor were: electric water pump, a serpentine kit (such as one without the compressor found on street and perfomance, with a mini power steering pump). running dual electric fans as well. i have no ideas about heads, roller rockers or not, what car, what manifold. please bare with me if i sound naive, i really am. any suggestions? i dont want a big throaty sounding car, if anyone has seen nash bridges, would like my engine to sound like the cuda when running. just very smooth, which i know has to do a lot with the exhaust. thanks for everyones help.

good post tech!


welcome 2 CHR orangecounty61
61 nomad wagon <- - - sounds cool, already
have any pics of this ride of yours, you can post?


"and you may have to keep reading to understand what these guys tell you" " I know I still do and I thought, I had a pretty good understanding of things "

You can never know to much!

has some cool specs on GM vehicles.

Biscayne Wagon 6 119 3790/3840 8.00x14 5 x 4.75
Biscayne Wagon 8 119 3785/3835 8.00x14 5 x 4.75
Bel Air Wagon 6 119 3865/3910 8.00x14 5 x 4.75
Bel Air Wagon 8 119 3860/3910 8.00x14 5 x 4.75

model/engine/wheel base in inches/weight min/max / tire size/ bolt pattern

max weight is 3910, so ill say around 4100-4200 when the car is completed after the sound deadning material is put in.

Richard,
How about I jump in on this, and with that, I hope I'm not butting in. But let's see if it helps "Orange County" some.
I copied your questions and have answered them for my project--a 327 build-up. Promise...I won't have my feeling hurt if you balk at some of my ideas. Just hope you and others will feel open to solidly critique it.

How much money will you spend? As much as necessary.

Is there a time frame in which this project must be completed? No, I've had this car since '79! So while I'm just starting, I've learned to be patient (LOTS of project cars for my son...Now it's my turn!)

What is the weight of the car? Should come in--when completed--at around 3400 lbs. I'd think.

Will the motor have to pass emissions? Nope.

Does the car have power brakes? Nope--will have 4 whl discs though.

Will you do the work yourself? An awful lot of it, yes.

Do you have the proper tools? Yes.

Are you hung-up on the 327 or would you be just as willing to build a 350 or a 383? I've GOT to do this motor. It's all about always wanting to build one--since '68 when I had my other '55 and had a screaming little 292. I have this small journal 327 available and am determined to build a stout motor out of it--just for grins and to capture some of "the good old days".

Do you have access to a good automotive machine shop? Yes a very reliable one who does alot of "old iron performance stuff".

What transmission will be used? The Keisler Tremec 6-spd (Ratios: 2.97, 2.07, 1.43, 1.0, 0.80, 0.62)

What rear end? Currie's 9" w/disc brakes
What gears? 4.33

What % will be mild-mannered street driving and what % of the time will you be down on the loud pedal? I'll be using this for limited (1-2 times a month) cruising but will have to run it once at the strip--just to see.

I'm planning on the following build-up:
Bore .040 over -- it's already .030 with all the necessary line boring and decking, magnaflux etc.
Eagle Crank Stock Rods TRW pistons .125 dome Dart Pro 1 64cc Alum. heads (2.05 / 1.60's with 1.55 dual springs) Isky roller rockers Isky Z-70 cam .548 .264 adv. dur. 108 degree centerline Solid lifter ('cause I like the noise and don't mind the maintenance!) Edelbrock 2x4 intake (I know it doesn't match the build-up, but I want THAT look, you know?) MSD ignition Hedman headers with a CCI 2 1/2" exhaust system thru Turbo's or Flowmaster's..not sure.
Yes, I'm aware it's impractical with todays gas and plan on 1/2 & 1/2 92 octane & Union 76 race gas.
I've had many friends tell me "your whacked!" "Why a 327??? You could build a monster 383 for the same money!" Answer: 'cause I want to and I can! I really do want comments and questions. I've waited a lOONNNNNG time for this and I want to do it right--while still having "The sound" and "The Look". So dive in and maybe it'll give Orange County some ideas to use or avoid. Thanks.

IMO - I don't like the smaller journal cast crank 327/302/283's. GM recognized this problem about 67 and made the 327/350 larger.

Years ago I destroked a +.060 350 with a 3.25 stoke forged crank for my street rod and later it ended up in a successful circle track race car.

The reason why a 337 ci is so successful. It was in an restricted carb class. So both a 358 ci and a 337 ci make the same amount of power only the 337 has an additional nearly 500-600 rpm.

Back to your question. I've always tried to run enough cam that I could get away with 10.5 or so compression even with iron heads.

If you have the budget get longer rods like 6.125 - 6.250 Run KB hyper pistons in a sub 7000 rpm motor and Forged flat tops in a motor expecting more rpm or spray.

I've always like Crane cams and their Power Max lineup. I used the PM 272 for years in a 3500 lbs car.

Use good heads with 2.02/1.60 and you need 64 cc to keep the compression up with smaller cubes.

I like the higher rpm rated dual planes for street motors with sub 200 cc intake volumes.

I say build a 350 or 383, my buddy has 12 grand in his 327 40 over, the works, 600 inch lift cam, etc, 410 gears, runs 12s. Yeah i guess if thats what you have always liked or whatever but torque gets you down the track, not a high rev.
