L34
RPO code for a 350 hp/410 tq 396 big block engine found in Camaros, Chevelles and Novas from 1967 up thru 1970. It was not produced after 1970. The same engine was rated at 360 hp in 1966. This was the middle of the road 396 during the muscle car years. The only other 2 396 engines were the 325 hp model, RPO code "L35" and the top dog 396 RPO code "L78". The L34 engine used a hotter hydraulic camshaft than the L35 did. It also used a Quadrajet 4 bbl carbureator, and a set of oval port heads with 2.06/1.72 valves, casting code 3964290. The compression ratio was set at 10.25:1. The blocks were usually 2 bolt blocks (though some claim 4 bolts were avaliabe). It's also rumored some came with forged cranks while others say nodular. The L78 396 however used a solid lifter camshaft and a pair of rectangular port heads, a 780 Holley carbureator, a 4 bolt main block with forged crank and an 11:1 compression ratio.
The Urban Dictionary Mug
I LOVE GETTING THE FUCKING MUG
The wife absolutely loved it for her birthday

it was the best and it was so worth the 10000000000 dollars
Can we really send one to Trump? That's where mine is going. Anyone who gets it will see it as a compliment, I'm sure. Love my mug and love that new "urban dictionary" term: Celebritrash. It'll be in the mainstream dictionaries next week.
My friend saw the message on the cup ordered at a mutual friends house. We think it’s hilarious so had to put it on a coffee cup. Funny, great Christmas present. If she can’t use in public she can always use at home for pens and pencils on her desk!
Bought the "Bump Down" mug for my boyfriend, he thought it was the greatest and couldn't believe I'd actually found something with the phrase on it!
Great mug but i can't manage to get it out of my asshole again

First heard the term “Cheddar Headed” from the song Feel Good by the Gorillaz. Had to look it up and found the definition hilarious and at times very true! So......had to have it! Took it to work and it definitely made an impression. Hahaha!
This was purchased as a gift , and it describes the recipient perfectly . It arrived sooner than expected, and I am very impressed with the quality .
The mug I ordered was exactly as described on the site. The shipping was fast as well. I will buy from these people again.
Cute mug, arrived promptly in great condition. I like how you can choose background color & change wording. Will feel cheerful when drinking my coffee in this :)
Heavenly Mug This mug has been sent from the heavens. I'm too broke to buy it. But one day... I will. I will be mugged, dammit!
Why am I here? I don't know how I got here, but I can't stop writing weird things on the cup...😅 Help me. I have a test to study for. A family. Also, if I wasn't broke I would buy 10,000 of these mugs. They look highly entertaining. Love this website, and I probably will fail the test. 🙃
I took time designing it but wasn't sure, online tools being what they are, that what I was seeing was for sure what I'd get. Very much appreciated the customer service communication which verified that what I'd designed was what I wanted, and the shipping was quick too.
Item came on time as promised
Came within a week and it's exactly what I ordered, my friend will love it!
