350/325?
« on: July 08, 2013, 03:29:46 PM »
I was looking at my 69 Chassis Service Manual today, specifically Q-jet part numbers and saw a reference for 350 (325) horsepower carb number 7029207 manual trans. Can I assume this is for a Corvette 350 or was it used in anything else? I question this because someone has this carb on ebay saying it's for a 350/300 and that number isn't correct for that engine. 255 LM1 and 300 is 9203 for manual and 9202 for auto.

The 69 Chassis Service manual has a typo. The 7029207 was used on the 69 Corvette 350/350 engine. There wasn't a 350/325 engine in 1969.

In 1968, you could order a Chevelle with a 327/325 hp engine which was really strong.   A friend had one outfitted with all the SS goodies, bucket seats, 4 speed, console, etc.. and it would blow the doors off of SS396's.   I'd love to have one of those now.. :)

Yeah!! I like the 327 engine a lot more than I like the 350. You can wind the heck out of them like the 283's and 302's. Ehhh, big blocks are OK for some people, I was never really impressed by them and have been around a lot in the 70's, lots of torque, but I like the ear shattering whine from a 283, 327, and 302 when they are upstairs. I had this one in the 90's. 327/375 fuelie engine, ports opened up a bit, 12 bolt 4.56's, manual valve body T350. This car was a solid 12.5 car when I bought it. It was a beast.

Gary,

Born a small block guy myself, but "there is no substitute for cubic inches". I always thought 8 grand in my Z was the ultimate thrill (after rolling through the water at my local Shoney's) until I tried the same thing with the vehicle in the pics, which made a believer out of me - even a warmed-up LS5 motor was capable of scaring the daylights out of my wife, and swapping ends after mild pressure on the accelerator pedal. Maybe you just haven't driven the right combination to convince you -

(The rest of the story: I sold this car year before last to afford my '68 Z - wife said if I brought another one home, one would have to go, or she would - )

Regards,
Steve

I've been in plenty. The torque they produce isn't for the faint of heart that's for sure. You have to know what to expect with a BB. I've been friends with this guy in the Air Force since the 70's from Havre De Grace Maryland that had a LS6 well over the stock hp with a tunnel ram in a gutted 66 Chevelle, full floating rear, full cage, 4 speed, the works, one seat. We were sitting in 12 noon traffic at a light with cars everywhere, doing a test run of all things. He says hang on and lets it fly. I'm hanging on for dear life to the roll bar and all I see is sky thru the windshield. A few locals in the area said the wheels were off the ground by at least 2 feet. That was my first time and not my last. Not sure why, but I always thought there was too much muscle needed to control a car like that. With a small block you have that same power but the torque isn't throwing you around your throwing it around, as in your throwing the car around. I feel more in control somehow. In 75 I had my first 69 Z. 12.5's, 140 cam, port work on heads and intake (that's when I did my first divider cut out under the carb), 750 dbl pump, 4.88's and for me that was way more thrilling to drive and easier to control. I always believed that big things came in little packages and never needed to compensate with a big block...at least that's what my wife would say. lol.

Oh yeah, something else...I've seen a few big blocks blow too. I think they are way more messy than a small block.

I supported that when I posted a couple of pictures of my L78's original block under "Orphans" a while back - at least it wasn't one that I had built, nor did I blow it (came with the car from a previous owner's indiscretions). Bad messy -

Must have been a sign of the times - I ran Manley 12.5:1's (still have them) in my '69 Z in '75, Erson Hi Flow 2H hydraulic stick, stock 186 heads, factory 4.10, headers and an 850 DP Holley in mine, sure was a beast. Local machine shop told me I'd pound the mains out of it in 10K miles - bearings still look new after double that. Miss the good 'ole days -

Regards,
Steve

I'm right behind you at 42 years - the threat was just that, no real intentions (as far as I know !). I've missed a lot of deals over the years, but mainly due to severe shortage of mad money when I needed it. Three kids in college today doesn't help in my old age, either -
