So...Pale_Roader ..What are you putting a DOHC into? I had a girlfriend years ago that had a Shelby Daytona turbo II....That was impressive...
1970 Challenger.
The plan has evolved from a 426 Hemi or 6-71 blown 400 or just a savage N/A 426 stroker (lowdeck) wedge build in a road-race car to a smaller, more livable and much more modern (read: efficient!) road-race ready street/daily driver. I had most ov the parts to build that blown engine when i realized that having a 750+ HP big block just wasn't going to be much fun (now there's a riddle for ya...)
I'm still pawing around engine options, but whatever it is will be smaller, electronically injected, high-tech, and come already bolted to a 5 or 6-speed manual.
Running 11's or 12's in street trim and getting well over 20mpg with zero reliability issues is fully within the grasp ov what i'm aiming for here...

Ever thought about a supercharger......like from the supercharger store? Mopar Muscle did an article using a 318 and bolting on a super charger -it almost had 600 rear wheel hourse power! 11 second quarter mile times. They are now going to do a 273 and shooting for 500 hourse power and 25 miles to the gallon!
No, thats about as far away from what i'm trying to do as you can get. 600rwhp and 11's...??? Mustangs can do that with 400 or less, some a decent amount less, and still not kill you at the pump. Besides, i've become a big fan ov naturally aspirated power. Anyone can go fast with boost...

just finished it up about 3 weeks ago. 74 duster with reringed 400, pistons way down in the hole, small summit cam, its close in spec to a factory hp cam, performer intake 1 3/4" headers and a holley 750 vac secondary. i really wanted to run the thermoquad but it was giving me a hard time and i just wanted to be out driving it. t56 with 3.73s and 245 45 17s all around. i never wieghed it. i just took it on a 2900 mile round trip and got 19 mpg on the highway. my wheel alignment was really far out and it still needs some tuning. there has to be more left in it. i didnt want to do a full build on the 400 as i wanted to drive it first and see how it all worked together. im not going to be hitting the strip too often anymore so i built something that would just be fun. with gas prices what they are, i cant see how anyone could not factor them into a build. one thing i would like is to raise the compression when i do build it.then there ar eplenty of other options, i wonder how a long rod and short lighter piston would effect mileage, hp and torque. then of coarse there is the 451 or 496-500. i dont want a big choppy cam i want to keep a lot of torque down low in my cruise rpm with good throttle response. im not really looking to run 11s, more interested in driveabliity and an overall efficient combo with some good mpg, now if i could get all that and go 11.50 on a good day, that would be cool.
