Re: Early 327 engine information gurus?
 

Well i just finished my 67 build and it has the 327 375 with hump heads

I added power steering and all the other bells and whistles

Ive added some pics of how i did mine maybe it will help

I mocked everything up then sent it out to powder coating

Then reinstalled everything

My truck was not a factory PS truck. I went with all factory 68 Camaro brackets on my motor and a banjo style pump. Then factory hoses from pump to box. Its a little tight but it all works fine. Dont have any good pics when I had the truck all apart installing the motor.

Thanks. Yours is a nice looking mill as well. I have a vintage intake with the oil fill, but my machinist talked me into an air gap. I'm not sure that will stay. It's a '68 truck engine also using 2.02 heads, flat tops, and cam. We were shooting for 325hp. I had a '71 truck 350 for that truck but found out about the 327 for sale and had to have it. The 350 I plan to build a 383 with for the '72, and set the original motor on a stand.

I knew a guy in the early '80s that had a sweet looking '77 K30 single rear wheel 4spd Silverado. Black, lifted with 38" tires. Great looking truck. He and another friend with '79 F250 when 4 wheeling and that thing was ripping it up. made that F250 look wimpy. It turns out it had a built a 283! Not what you'd expect to see. But that motor sang so sweet climbing hills and churning through deep mud. I was very impressed. The F250 had a choked out 400

another fan of 327s this one out of a 67 truck

Re: Early 327 engine information gurus?
 

Woo, 375!
Great to see all the 327 love. All great looking motors. and we know how great they run :cool:

Re: Early 327 engine information gurus?
 

That helps a bunch...I only have that top alternator adjusting bracket now

Re: Early 327 engine information gurus?
 

The 327 you have was and is a great motor. Dependable old school foundation for easy upgrades like cam swap, intake, headers. Those motors can scream.
I have one in my 68 Camaro. I actually have another complete 65 250HP original engine from oil,pan to distributor sitting in my shop wrapped up. Corvette guys love ‘em.

Re: Early 327 engine information gurus?
 

A car built around the 327. Game changer!!

All double heads are not Fuel injection heads.
The same double hump castings were used on everything from 327’s 275HP and up. All double hump heads came with either 1.94 or 2.02 valves. Only the lowly 250hp and some others like the 310hp had the small valve heads (1.74). The double hump heads are not rare at all.
The 300hp also had the same casting number and double hump identifications as their 2.02 big brothers. The 300hp has the 1.94 intake valves. Only the 350hp and 365 and 375hp motors came with 2.02 valves.
2.02 heads also had the side of the chamber, nearest to the intake, machined/relived from the combustion chamber from the factory. If you retrofit 2.02 valves to these heads and do not relieve the chambers you actually cut the port flow not increase it. It's mostly old inaccurate lore from long ago lives on never be replaced.
That said I would like to see a 327 with a modern set of Vortec heads installed on it. Would be interesting to see how it would run with some better flowing heads. They would drop the compression slightly as they have 67cc Chambers not the 64cc chambers like the original heads.
If you raced an all-stock 365hp 327 and a stock truck 5.3L in the exact same vehicles the modern truck motor would be faster. The 5.3L makes way more torque. And if you installed an equivalent cam in the truck motor, as the 365/375hp 327 it would be even worse for the 327.
For the record I have a 340hp 327. It is a great motor. But GM has leaned a bit since then.
Cheers.

327 engines are cute and worth about 50 Bubba points at small car shows but those heads won't have hardened valves seats in them and aren't going to work well with the gas we have now.

Personally I'd have to think it is rather lame to pull a good strong running engine out a car to stick one in that's only plus is nostalgia rather than practical. Build it for an older rig out of the 50's and spend the money to bring it up to snuff with camel hump heads that have had hard seats put in and a good cam = Bonus.

Re: Early 327 engine information gurus?
 

lame or not.....it's not prudent to put a 16 year old kid in 400 HP truck....:lol:
If I wanted to wake it up, I'd cam it, stick a set of Vortec heads and matching aluminum intake...again...not for a 16 year old with little driving experience...
