As for configuration,do you mean flat top ?If so,yes they are the same as yours.If I go with a 54cc chamber,then it should put me at 10.6 /1 !!:dontknow: I do however want to get in touch with a Viper Truck buddy of mine that likes playing with Super Chargers and see what he has to say !!He likes to be different too !!
When you say, in regard to your pistons, "They are the same as mine," do you mean that in addition to the flat tops, they are
also .167" down in the hole (deck clearance?) This "compression height" is an important consideration in piston parameters, and has to be considered as a part of the compression ratio equation.
We got the Wiseco pistons we bought because our good friend, Tom Wolfe had bought an identical set for his turbo motor, and we, being totally clueless, decided that the smartest thing we could do, was to build a
copycat motor to his, so that's what we did. He and Ryan Peterson have very similar setups, and both run like the hammers of Hell, so we just followed along in their footsteps. Our car is 95-percent finished and should be running, soon, so we can see if we did the right thing, and did it correctly.
Our compression ratio, with those pistons, (3.465" bore,) a .020"-thick steel shim head gasket, and a stock, un-millled head, is a true 9:1, which is about what we wanted for our turbo setup. Oh, the head is ported, with big (1.75"/1.5") valves.
The car this engine is going into is a '64 Valiant 4-door sedan, with a fiberglass hood, and lightweight racing (bucket) seats. No back seat, but a roll bar. My avatar shows a picture of the engine.
We're hoping for a race-ready weight of 2,600-2,700 pounds. We may be sorely disappointed; I had a '64 Valiant 2-door post car that I swapped a 340 and an 8.75" rear into, that weighed 3,105... no kidding.disgust
IF your pistons are, in fact, .167" down in the hole (compression height) like ours, it would mean that your compression ratio would also be at about 9:1, which would mean that your short block's reciprocating assembly would be a
perfect candidate for forced induction of some kind, super- or turbo-charging, which would easily give you the "kick-***" characteristics you seemed to desire, without ruining the driveability of your car with the long-duration cam and high-numerical rear axle ratios necessary to go quick with a highly-tuneed, normally aspirated motor. The turbo cars of Tom and Ryan have been shown to run their quickest with axle ratios of 2.76:1, which provides a great highway gear. The best turbo cams are short duration (220/220-degrees @.050") that idle like a stocker... so driveabily is not compromised with the rump-rump/no low end torque of a "racing cam."
And, if you can keep your foot out of the firewall, they say that gas mileage is actually improved with the addition of a turbo...
Interesting also, I think, is that Tom Wolfe's car, with a basically STOCK motor, cam, and all, ran a 12.95 @102mph in a 3,300-pound Dart Swinger by bolting on a junkyard Buick turbo. Your car would be much faster...
And, you wouldn't need a muffler, or a hood scoop... or, an expensive 8.75" rear; a "garden variety" 8.25" unit from a junkyard with it's 2-something gears would do fine (just be sure to get one with a Sure-Grip; you'll need it... and, most importantly, you wouldn't have to worry about MOST small block V8 cars at a stoplight... lol!
You pays your money and you takes your choice...
But, if you are even thinking about doing this, don't let Frank mill that head (hope it's not too late.)
Just some food for thought...
