Street / Strip 327 Small Block Chevy Dyno Test

11:1 Solid Lifter Cam 327 Small Block Chevy Dyno Test

[VORTECPRO]

We really appreciate all you guys who watch our videos. I would have never thought these 327 builds would be so popular, after we finish the 620 HP 467 build, followed by a drag test, maybe we can build a nasty production headed (186s) 360 small block with a big flat tappet and a tunnel ram. Thanks again every one! Meanwhile my kid will try and put his truck into the 12s in Colorado's thin air.

One of the greatest engines ever built and I'm a Mopar guy. Super job- it's a jewel- enjoy!

Da hell with the LS motor. Short stroke high compression masterpiece.

[howabouthetruth]

Yeah man!!! Basically 450+ hp ( depending on air density ) out of a classic 327. What's not to love. Subscribed.

I grew up on the 350 Chevy in the 60's-70's. My first car was a 69 SS/RS Camaro with a 350-300 w/3:31 gears and at the same time I had a 327 in a 1969 Chevy pickup which was a swap. It was an excellent, bulletproof, great mileage motor (around 17MPG in a 1/2 ton) and when I gave up on it it had 169, 000 miles and still ran fine. I sold the truck mostly because it was completely rusted out. We used to put carpeting in the cab corners or you would freeze in the winter and the rockers were mostly nonexistent. I had it in Vermont when I lived there for a year and the coolant would basically be slush with -25F temps that winter in the Green Mountains but never failed to start, even without a working choke. Pump the gas a few times and fire it up, shut it off for a bit to warm the coolant up, and then start and go. Nice to see these are still going strong with all of the new tech. But, us old guys remember the days.

Never been a "Bow Tie" Fan, but what is not to love about the 327. They had a sound all their own and with the large bore and short stroke could rev with the best of them.

Great build! I like 327 so much, I put a 327 large journal forged steel crankshaft in a Sbc 400 block, it now resides in my wife's Chevy Vega, , , , full roller engine, she shifts @8200 and gets her to WallyWorld PDQ, , ,

11:1 is key in the 327” engines. Just drove my 11:1 333” home from work tonight!

Im in the engine business. This was an excellent video. Also an excellent build.
Very professional.
Great job!

I would like to see what difference a set of worked vortec heads would do. I love a 327, I've tore a many big blocks a new ass with one. The good thing is the torque is easier on suspension on the street, so you can hook a little easier without blowing off the tires. Then the upper rpm pulls like a freight train. Love those little motors. I build mind with a 350 block and 307 cast crank and turn it 7, 500 rpm frequently. You are right, they need compression to run right. Great build.

I'll repeat my comment from the last 327. Very impressive for a fairly mild combination. Especially in a small cubic inch engine with outdated factory heads.

Excellent power & torque for the 327. Had a few over the years. Used to watch Grumpy Jenkins, amazing he was pushing 660-680 hp out of those little motors with iron heads & 15:1 years ago. A lot of finesse went into it obviously. I read he ran a 6.17 gear, 9, 300 rpm at the lights. Appreciate the post.

[kurtzimmerman]

that is one of my favorite engines of all time. these can build a lot more power if desired.

[txstang]

I was pretty impressed by the torque considering it is a 327-but 11:1 compression certainly couldn’t hurt. That powerband looks like that’ll be a fun pickup

[wbhink]

Very nice build! The 327 is nice compromise between the 302 and 350. Personally, I'd rather have the torque for a daily driver - 350-360 hp, 460-470 lb-ft, 9:1 pump gas, 5500 rpm 350 engine with a 2500 stall, RV shift-kit TH350 trans, 3.73 rear-end in a short-wide half-ton, an early '70s Nova or late '60s Camaro - dang you've brought back memories!

[dlow]

My favorite motor of all time. Just listen at her run.

[jrsgarage]

Small Journal Crank is the secret, RPM Revs faster than 350, 1/2sec. faster ❤️👍

[shitbox]

Impressive 327, will be a lot of fun. 👍🏻

[magster]

Sweet!
We're building a very similar 327 for my sons '31 Chev coupe. I never got to drive a hot rod to high school... this is the next best thing!
Thanks for posting :)

in 1978 I went to the Chevy dealer, I was going to buy a LT1 350 cam, I am a fan of solid lifter cams because my vary first car had the DZ 302 solid lifter cam in a 350 (194 valves) the engine was old and tired. well the service manager at the Chevy dealer told me he was going to sell me a better street cam that pulls better than the LT1 cam, OK. he went on and told me that he used to drag his stock 1970 LT1 Vett in the early 70s (in Florida), he told me that the L-79 cam pulls better threw the gears than the LT1 cam.
and I just happened to be building a 327, so I put the L-79 cam in it, it had 12.6: 1 compression, the pistons and ring gaps were tight, the Rod bearings were slightly loose and for only $150 I had luckily found a set of the better 1971 202 LT1 heads.
BB or SB I was out there blowing them all away, most all the cars got me off the line but she would catch them. the higher compression helped big time, I had to burn Sunoco 104 and at times she would ping if you stepped down too hard in too high a gear. the machinist that helped me build it told me that the short stroke has a slower piston speed so the tight pistons and tight ring gap will work well, just take a good 300 or 500 miles before I stated to play, , I took a 240 mile trip, and that did it ;)




today: well today I wished that I had built a 400 with the L-79 cam instead of a 327, and throw some high ratio rollers rockers on top of it, that sure would have been the the thing to do
