Re: Some "Dime Rockets" for the 4TH!
No worries Billy, just killing time. Right now the straight temp is -14, and the car is in the carport. I am way too close on this thing to stop now!

Re: Some "Dime Rockets" for the 4TH!
The Caprice would probably be the easiest body to find and definitely the least expensive but the Camaro/Firebird would be the better car.
And at this point in time, it won't come close to running with the 302s. |

If you look at NHRA's sheets, they list the same intake manifold for the 267 with a DualJet and the 305 with the 2GC; is that possible? (I am not familiar with DualJets, other than they look like the front of a Qjet.) Also, is either of the 79 intake manifolds (14007372 & 14007374) aluminum? The 78 alt intake 346260 is also used on the 76 and 77 305s, and the 75 and 76 350 2bbl. (Probably the 74 also; the tech sheet says 346266 but that could be a typo.) Quote:

Re: Some "Dime Rockets" for the 4TH!
I did a bit of research last night and found that the two intake manifolds listed on the 79 tech sheet are both for DualJet. In fact, I physically inspected a 14007372 number which is cast iron. I'm going to chase down the carb numbers next. Billy, I think you are probably right about supply and model usage; maybe it has to do with timing in the production year, too. My Monza was ordered in September 1978 and delivered in October.

Re: Some "Dime Rockets" for the 4TH!
I've been running the 82 267 Monte Carlo combo for a year now and I have to say the intake manifold on this car has to be the world's heaviest for a small block chevy. Love that dual-jet too. '

Re: Some "Dime Rockets" for the 4TH!
Been looking at some of these U/SA combos such as the late 70's Camaro with the 305-2V and the 80's combos with the 267-2V . At 180 HP vs. 150 for the 267 is it worth carrying the extra 600 lbs. with the 305 ? Which is the better combination and what other chevy combos may be the way to go for U ?

You could just do a Camaro and get both 78 and 81 facias and run both! |
Re: Some "Dime Rockets" for the 4TH!
'76 Chevelle is an interesting choice. With it you can run the 305 2bbl in U, but also have the option of 350 2bbl, 350 4bbl and 400 4bbl if you decide to make a career with the car. The '75 Chevy II 262 is another option for U.

Dwight,
I've been talking with Billy about such a combination as I have a near original 1976 Chevelle Laguna S3 in the shop now. Original 305 car |

For some reason though, the 1.21 Dual Jet doesn't seem to work as good as the 1.18 2GC ??? |

Re: Some "Dime Rockets" for the 4TH!
Kinda what I was thinking...Not being an engineer, I don't know if one restriction in a carb over rides the other or vice versa..
Could have something to do with the booster/ venturi cluster being bigger in the Dual Jet...Seeing its part of the bowl casting, you are stuck with it. Take a look at what some of the fast 4 GCs are using... |
Re: Some "Dime Rockets" for the 4TH!
Yes . . . what some are doing.
Back in the day of modifieds, they would use the body of a Holley list 4224 660 cfm carb fitted to an 850 double pumper base plate. The carb body would be reamed from the bottom to match the 1 3/4" size of the throttle bores. Voila! The new "blended" carb would flow in the 750-775 cfm range, but keep the small venturis for crisp throttle response and high quality fuel atomization for under 300 cu in engines. I suspect the difference between a 1.686"/1.093" carb and a 1.686"/1.186" carb would not be as great as one would fear. |
Re: Some "Dime Rockets" for the 4TH!
From what brain cells that I have left, I seem to recall the 1.21 Dual-Jet flows about 290 CFM, the 1.18 2G about 320 CFM, the small-base 1.092G about 260 CFM. I've never played with a large-base 1.09 2G but I will assume(there I go ASSuming again) that because of it's larger and better shaped airhorn it would do better than a small-base 1.09.

Re: Some "Dime Rockets" for the 4TH!
For the AMC guys: 77 Matador Coupe, 304/180 in U? These are a unique car, no doubt, and if someone wanted one, there are four (yep, four) of these coupes in my local salvage yard, including a very nice tan on tan model. Ahh, another snowy Saturday...

Re: Some "Dime Rockets" for the 4TH!
Isnt the 221 similar to the 260 and early 289 5-bolt bell? I thought there was a C4 bellto 5 bolt block but maybe it's aftermarket?
|
Re: Some "Dime Rockets" for the 4TH!
Billy a few years ago there was a 255 mustang that was like .-3 after lots of work. The tiny ports on a 255 are laughable.
I think I saw it in Nitro's Joes Stats. "Red" comes to mind for some reason, either the mustang was red or the guys name was red...or was it "Rich".... I got "craft" disease, Can't Remember A Fing Thing. Joe, yes the 221 was the original windsor before boring/stroking up to 302, but I think it only had the fordomatic tranny which was replaced by the c4 in 64 or 65. I think the last year of the 221 was 63. But, the 289 had 5 bolts in 64 and the c4 started in 64..so maybe there was a 64 5 bolt c4 for a 289? But I really don't think so. I'd say it would have to be aftermarket. |
Re: Some "Dime Rockets" for the 4TH!
If you really want to throw money down a rat hole, just sleeve all 8 in a 260 block.

Re: Some "Dime Rockets" for the 4TH!
Mark, Billy, man, you guys are making me feel really old. Talking about 221 and 260 Fords, LOL! I Haven't heard of anyone messing with either of those motors for 40 years. One of the neighbor girls had a boyfriend back home that ran a 63-64 Fairlane with a 260 when I was a 13-14 year old kid. Her brothers and he would prep the car. They'd flat tow it down to Freedom Dragstrip (now called New Hope). Then come home, change the rear tires, put the mufflers back on it, go cruising on Sunday nite, show off the trophy at the Drive Ins. That would've been about 1968. Even being a dumb country boy buried in the sticks, I remember there were a lot of nice cars running around back then.
These would be tough engines to find parts for, today. Unlike 265 or even 283 Chevy's. I doubt much of this stuff was hoarded or held onto. Heads, intakes and usable carburetors would be fun! What about legal pistons. Other than maybe something left on a dusty shelf, could you even get pistons for either of these engines, now? Talk about a challenge |

Make it a 77.

Re: Some "Dime Rockets" for the 4TH!
77 is a big change with the bumpers. What's wrong about the '78? Run it as an LT and it is still in U. Much easier change.

Re: Some "Dime Rockets" for the 4TH!
I thought that the 77/78/79 were all the same minus grilles and tail lights?!?

Re: Some "Dime Rockets" for the 4TH!
Are you discussing Camaro or Caprice ?
|
Re: Some "Dime Rockets" for the 4TH!
I believe that Mr. Toller is talking about a Caprice.

If this one was still available, I'd be on the way right now. Note: since this thread started, the 82 was brought back to the original 157 hp. ( in the Wholesale 302 2v Massacre Reduction) I don't mind pointing this out , because it is now "stick only" , as it should have been all along. Nobody is going to build one anyway because everybody knows you can't win with a low class stick shift car. |
