327 chevy really all the hype?
i had a guy who told me that the best engine to race would be the 327 and he said he could build it to whoop a 350 or any other engine.. so what im asking is... is this engine really that capable of 'whooping butt'. Me personally i'd rather have the 383 or a 400sbc... What are your thoughts?

geezer69 02-05-2013 07:15 PM

no it aint so. whoever told you that is bout as much a builder as i am. and that aint much. hahaha.they were and are great little engines but more cubes gets er done.

demarques_191 02-05-2013 07:19 PM

well he was saying how quick it can be due to the shorter stroke but i was telling him its gonna have to rev higher to keep up with the lower torque of the 350...

jtz55 02-05-2013 07:35 PM

sounds like u were talking to a old school drag racer stuck in the past who also doesn't read anything printed after 68 lol

a 327 can be built to almost keep up with an equally built 350, it can come REALLY close in terms of total power as a 350, but in the end a few more cubes will ALMOST always give you an advantage.

Going with the bigger bore of the 400 changes the game as you can run much better heads and it'll walk all over the 327 and 350- provided of course you can keep it together 400 blocks are notorious for failing around the 550hp range- which the 327 and 350 can also be built to hit.

yes he was a old head and there is no arguing with a old head, i mean the only good thing i hear about the 327 is it revs faster and can go into higher rpm's easier than the 350 or 400... I also hear you cant put a 327 in a heavier vehicle, its better for lighter weighted cars...

Back in 64 I think it was Chevy had a very nice 327 w/ 375 HP that was quite a screamer for those days. Steel Crank, 202 Heads, max HP over 6000 RPM's, it was quite impressive right off the showroom floor. It's still a sought after motor for some of us old timers (makes us feel like a kid again I guess :D)

Actually a few decades ago I had a fully built 327 SPHE (Special Hi Perf Engine) in a 69 Chevelle. .060 over, hi dome pistons, 202 fuelie heads, solid roller, TM 1 manifold, dominator carb, M21 trans, super shifter, 488 posi, and all the other goodies; ignition, headers, (3) fuel pumps in the trunk, etc... I do have to say after 50-60 other hi performance vehicles that one will always be one of the most insane vehicles I ever owned. The sob would catch air on the street anytime you wanted, it revved to well over 8K on a daily basis, and after 11-12 Big Block Chevelles since then, that 327 would run circles around each and every one of them.

Hell it would probably give my Sierra a good run

NOT :thumbup:

Probably a good guy but very old school!

I won F1-E/HR in the 1968 AHRA Spring Nationals with a 327 CI SB Chevy engine (13.32 ET) but was eliminated in the first round. My cousin, Mark Taliaferro, eliminated me in the first round in his '55 Chevy "El Toro" with a 327 CI engine. A '65 Dodge 426 Max-Wedge was F1 Hot Rod class eliminator (11.30 ET) .

My 3900 lb. '59 Impala was equipped with a 327 engine, 30-30 camshaft, new "291" double hump heads ported by Joe Modello, 3-2 barrel Rochester carburetors from a '66 GTO, Tri-Y headers, Bruce slicks, a B-W "slick-shifted" 4-speed and a 4.56 Posi-traction rear gear.

When the 327 came out, it was a revelation. Up 'till then, most guys were running 283s, some as big as the 301- but the 327 was a whopping 44 ci (15%) jump in displacement over the 283, and that difference was enough to put the 283 pretty much out of the picture unless you were class racing. The 327 also brought about the big valve heads w/the bore size to take advantage of them.

The size difference between the 350 and 327 was a lot less (~7%) and they both had a 4" bore, so the power difference was nothing like the 327 vs. 283...

I love the stories of how fast cars used to be back in the sixties and seventies,way before we had the good after market heads we have now.
The guy that had a doug nash 5 speed,Lee sheppard Welded straight plug cast iron heads,that revved to 11,000 rpm, was compared to the street guys that were running bias ply tires,3 speed saginaw low boys with flat heads
Yes,they were fast,40 years ago.

I watched a special event at boundary bay airport in 1975 where special guest racers Dick Landy and Bill Jenkins were there for our first night race.The pro stock guys were running 9.0s

this day and age you can find street cars with twin turbos and air conditioning that run 9s.

what kind of 327 was this old guy talking about? probably a small journal 375 hpGM engine. Today that is a rough running,high revving fair performing engine.The 11:1 CR is not pump gas friendly and the 30/30 cam has many times over been improved since then.

If you REALLY wanna be chastised, tell folks double hump heads were obsolete in '69. It's true. The 041 and 492 castings are FAR superior to the 46xs. I never liked 291... Lots of work to get them up to snuff.

It's even more "fun" when they learn only a small percentage of 327 heads actually came from Chevy with 2.02" intake valves. From what I saw when these engines were still around en masse, 2.02s were strictly in 365 and 375 HP versions (365 was the same engine with a carb instead of the Ram Jet injection).

327 is a GREAT little engine ("little" being the operative word). The rod/stroke ratio is a "perfect" 1.7:1. Those puppies WILL rev "to the moon" (AND live!). In an "all out" race effort, still a good choice for a lighter car. The lack of low-end is it's "Achillies' Heel".

In the mid- and late '60s, there was the 327 "High Torque". It was used in trucks, including larger ones. Small valves, small carb, tiny cam. All done by 4,800, but pulled real strong right off idle.

Brings back memories of my first few years in "the machine shop".

We paid Joe Mondello $700 (including shipping) to port, polish, flow test, install screw-in studs and set up the "291" heads for the 30-30 camshaft. We purchased a pair of new "3917291" heads from a Chevrolet dealership for about $200 and shipped them to Mondello. I also furnished Crane "green-stripe" dual valve springs which were popular at the time.The labor and cost for those parts was in 1967 dollars.

I purchased a 375 HP, 327 CI short block from a local Chevrolet dealership for about $400. It came fitted with forged "pop-up" 11.25:1 pistons and a forged crankshaft. The Chevrolet dealership helped a lot with our racing because they were performance oriented. In 1968, they received one of the sixty nine 1969 Camaros COPO with a ZL-1, 427 all aluminum engine. It was #6 COPO 1969 427 Camaro and was eventually sold to Jim Hall in Odessa Texas. He pulled the ZL-1 427 engine and used it in his Chaparral SCCA race car in 1970 and the Camaro body was sold locally without an engine. .

How about the chevy 302?? What do you guys think of that? There's an engine from the past that is never mentioned.

vinniekq2 02-06-2013 04:01 PM

no one mentions the 262 either?
