327 Set-up
Hey guys [and gals], I'm planning on swapping out my LG4 305 for a 327. The 327 will be rebuilt, of course, but I have some questions on what would be a pretty good set-up. I used Desktop Dyno to figure some of this out, and so far, I think I'm gonna go with World Sportsman II 64cc iron heads, a Comp Cams Xtreme Energy .447"/.454" lift cam, Edelbrock 600cfm carb, and Edelbrock Performer dual plane manifold. Would this particular set-up work well, or would it work at all? Any tips and suggestions are much welcome. Thanks

Shorter stroke.. Unique.. Just as good as a 350 as far as I can tell. Quicker revving as well. The calculations from Dyno2000 estimate 365hp and 390ft/lbs. with the 327ci and less hp and only 15 more ft/lbs with 350ci... so ... Fine with me And besides that, my "Z" is already a Frankenstein, so why not a 327?

thegeneral: I do plan on balancing it. And get that Impy decked out nice
.. And as far as a debate.. This is a suggestion thread not a debate thread.. lol I'll overlook it though if it arises. Thanks for the comments. I'm off to work in a few minutes and won't be back until Friday so surely I'll have plenty of replies by then.:lala:

That combo should be OK; reasonably well matched components. Except, I'd think you could get heads that would work just as well in such a non-demanding application, for less money than the S2s; unless you already have them laying around. With as low a top RPM as the cam and intake will enforce, you don't need big flow numbers; for that matter, 305 heads might work just as well in that setup, since they'll give a bit more compression but still have enough flow to feed the little motor up to the limit of the cam (5500 or so).
There's nothing special or unique about a 327, as far as that sort of thing goes. Think of it as a 350 that has some of the inches left out, and you won't go too far wrong. Anything that will work well in a 350 will work about the same in a 327. About the only difference is that you'll get about 7% less for your money because you'll have about that many fewer cubes multiplying your dollars into power. Displacement is usually the cheapest power you can buy.

I'd say Vortecs would also work quite well, of course you'd need a new intake too though. I'm not a real big fan of World S2's to begin with.

However, IMO & just for my , would'nt saving up for a 350/350 be more gentle on your wallet in the long run?!!

P/N 8016 Weiand Stealth
Both intakes are good over 6K (6.5K edel and 6.8K Holley as advertised)
Comp - XE274H or 284H would be better cam choices (RPM wise)
and a set of Dart 200cc heads (2.02/1.60/64cc)
top it off with a 750 (whatever brand carb)
That is my suggestion, granted I have only rebuilt one motor, but from what I have read (which is alot) this appears to all work well together.
Anyone is welcome to flame me as I am learning, the other way (no money and to young to have build as many engines as I would like to have.)
One thing is you should give yourself a budget as these guys are great at working within a budget

don't bother with a 327, unless you have some sort of obsession with them. especially if it's a 350 turned into a 327.... the magic of the original 327's was the small journals..
a 350 destroked to 327 won't spin any faster the journals are the same, the rods are the same, the pistons are the same ther's a smidge less stroke.. not doing much for the wieght of the crank...
rather than destroke it.. leave it, drop a set of vortecs on there, lil cammage, and you'll be burning the rubber off.
really depends on what type of power your looking for, to what type of combo your looking for... street car... fun street car.. weekend car.. stip/ street car?

Tryin' to get a fun street car out of it. May just have to go with a 350 instead because I'm not having much luck on the 327 part. lol. Hard to find around here, but hell, so are 350s these days. Junk yard doesn't even have any If anyone has a 350 complete or partially complete for a good price, I'm quite interested. lol

I think the Xe274 or 284 cam would be pretty radical in a 327. If you run the smaller cam then vortecs could be a good route. If you have to have a bunch of machine work done on them to use a higher lift cam then your $'s may be better spent with aftermarket heads.

The "magic" of the 327 wasn't ENTIRELY in the journals. The shorter stroke results in lowered piston velocity at a given RPM (shorter distance to travel and same time to get there)....which means less energy is used to speed the piston up and slow it right back down. It makes the whole reciprocating process more efficient and therefore lets the engine increase speed faster. I'll admit that it's not a HUGE difference, but it is there. The power you gain from going to a larger stroke engine (i.e. 350) is much more significant than the losses due to piston velocity.
327's are still cool though.

i think a set of vortecs and the 274xtreme cam would be pretty sweet, that cam might peak around 6300 or so with the smaller engine, get some gears and a good stall, 3000rpms' or there about, and it should be a good running engine.

Well.. Ya know, if ya think about it and actually understand it, it makes sense. But like I said a ways up, this isn't an argumentative thread. Just a tips/suggestions. And anyways, I'm just gonna get a 350 and build the **** outta the bastard. Thanks for all the help you guys.
