Some "Dime Rockets" for the 4TH!

[Billy Nees]

Good morning! Ready for another "Dime Rocket"launch?
1981-82 Camaro, Malibu, Monte Carlo with 2V 267/150.
I can't believe this one hasn't been done ever! It gives away some cam and valve size to the 262 combo that we all know works but it also gets back 15 HP! Down side would have to be getting cars light enough to run U and it's probably stuck there. It would probably even work with the 7.5 rear (4.56 best ratio) and a short slick which would be lighter and cheaper. Sorry Dwight, this one's auto only. It actually has a bigger carb than the 75 262.
Just one more comparo, there were a couple of good running 229 V6s around so we know that they work, the 267 is rated 2 HP less than the V6!

Hey Billy, how about a 4 /140 Vega ??

[Bobby Zlatkin]

Now this is a fun thread.

Much better than the ones with all the pissing & moaning.

Any good undiscovered AMC combos out there?

I have always wondered about that one, BIlly. Does the 1.375" throttle bore front-half-of-a-Quadrajet carb used on the 267 actually flow more than the 1.686" throttle bore conventional Rochester 2-bbl on the 262?

My dime in the pot today may stretch the limit because it is EFI, but it has proven potential.

96-99 Jeep Grand Cherokee 242/190-175/170 MPI
2WD of course! One of the best flowing cylinder heads offered on a pushrod American I6, lots of blueprinted compression, more than adequate camshaft. The offroad guys have developed lots of stuff for this engine and the knowledge base is broad and deep. The throttle body flows over 450 cfm according to Chrysler and there are several "tuneup" controllers available that are affordable. AMC Torqueflites bolt up and some years used Dana 44 or AMC 20 rear ends.

There is a racer in Div 1 (I cannot remember his name) who runs this same engine in a late 80s Comanche pickup and the later engines are even better. Several superceded parts should be listed in the tech bulletins that cover intake systems and the cylinder head that would possibly be even better than the current listings.

This is an R, T, or U car depending on year and model and you could even squeek a 5-speed into the 96 model.

We're up to $.20 in the pot now!

75 262 uses a 1.09 venturi 2g. 76 uses 1.18 venturi carb. 267 uses the big 1.218 venturi dual jet. 1.18 2g flows about 320 cfm, big dual jet about 300 but it is more difficult to make work.

The Division 1 racer who runs this combo is Bob Salemi. I believe Bob got IHRA to allow factory roller tip rockers on this engine also.

You had to bring that one up, didn't you. I'm vaguely familiar with Bob Salemi's truck and although it took him a long time to sort it out, once he did it flew.
That one sent me scrambling back to the guide to check it out! While I was there, if you can, enlighten me on the 96 Dakota with the 153 4 cyl. Is that based on the 242? If it is then that puppy at 115 HP could be a kickass W combo.

[Dwight Southerland]

The 153 may be the 60 degree V6.

[Billy Nees]

Engine guide says it's a 4 with same bore size as the 242.

world of difference in the 150 (2.5l) in a dakota (ohc) and a pushrod 150 in a jeep...

the dakota is based on the 2.2 omni with a taller deck height

the 150 jeep is a sawed off 232 kinda...
