were there any hopped up stock 327's - The 1947 - Present Chevrolet & GMC Truck Message Board Network

odog · 03-05-2008, 07:12 AM

I was told by my buddy to see if my 327 in my 67 3/4 ton was one of the hopped up models. What is he talking about? What am I missing?

bglad420 · 03-05-2008, 07:21 AM

He doesn't know what he's talking about. Maybe a large journal 327??

odog · 03-05-2008, 07:45 AM

Thank you, I didn't think he knew beans, but I've been wrong before.

roughedup72 · 03-05-2008, 07:56 AM

Maybe he was talking about the 327 with 300hp heads or double hump heads also known as camel hump heads.

Eddie H. · 03-05-2008, 07:58 AM

The 327 was available in cars producing 300,325,350,365, and 375 HP
but these were never factory installed in trucks.

heavy71chevy · 03-05-2008, 07:59 AM

They only went at the most i believe to 375 stock and that was a corvette 327 turbo fire (my motor) the diffrence is in the valve sizes and the heads..thats about it

powerbench · 03-05-2008, 08:01 AM

or maybe an L-79? 327/350hp

powerbench · 03-05-2008, 08:12 AM

aren't the 360 to 375 hp models fuel injection in a vette..?

**too much stuff** · 03-05-2008, 08:13 AM

I believe the 365 and 375 hp could only be had as fuel injected...

chip46wis · 03-05-2008, 08:21 AM

Correct on the fuel injection------

odog · 03-05-2008, 08:37 AM

Thanks to everybody for helping on that. I wasn't sure what he was talking about, but I knew I find out for sure here.

heavy71chevy · 03-05-2008, 09:49 AM

Oh yea..i forgot..thanks for catching that guys..I have the L-79 out of a 64 vette...nice torque and gets decent milage..if its stock wasnt like a 200 horse motor ?

**special-K** · 03-05-2008, 04:16 PM

250hp was pretty common.

slammed1 · 03-05-2008, 05:05 PM

right on,250 and 275 were common,and a large journal didnt appear until 68. The same block is used in a 68 350,327 and 302 all because the same bore but different cranks.

I got a 66 impala 4 door from a friend and yanked the 275 hp 4 barrel 327 out of it and built it up for my 68 Nova drag car. The engine originally had small journal forged steel crank,2 bolt main,1.94/1.50 valves in 64 CC heads,and cast pistons. I bought some .100 domed pistons,opened up the heads alot and went with undercut stem swirled/polished 2.02/1.60 valves with screw in rockers and guide plates with a single plane intake and 750 double pumper and a .558lift .312duration solid lift cam.........when it was built and started racing it I was shifting at 7800 rpms with a 4500 8" stall and 4.88 gears. Very nice strong reliable engines but in todays stroker world not as popular.
