We played with the idea of possibly selling the 144, and using the $$ towards the new motor. The 671 is a consideration, but of course as always, budget would become a problem. I thought it would be nice to keep the blower because of the current setup of the vehicle. I will have to post some pictures so you can get an idea about what I am talking about.
I've heard of slow blower cars before.... cars that don't make huge performance gains based on the addition of a blower.
Correct me if I am wrong, it’s been awhile since I've been able to play with anything other then a Toyota. (I hate toyotas)
383,.... long stoke small bore..... will make bigger low end torque then the 350. Displacement is larger also, so more hp. Now your saying with good heads and cam, you can make 500 horsepower up to 5000RPM easy with just a stroker: Natrually Aspirated. Now, even though the 144 blower will not displace enough air to rev the motor past 5000 RPM, won't it still make a substantial difference when it comes to adding to bottom end torque. How is it that it will breath naturally just fine, but with the addition of the 144, its choked? Meanwhile, its a 383,.... would you even want to rev a 383 past 5500-6000RPM?
I think what I should be asking is what is better for drag racing, light to light or track... being able to rev to 7-8000RPM or having the power band closer to 3000 to 5000 RPM?
Sorry if this sounds a little distorted, it’s been a while since I have studied this stuff.
With the 144 you will create the power at a lower rpm,without you wouldn't have as much low end torque but you would probably make more peak power above 5k. It really just depends how much power you want. A mild blower would tend to make the car more streetable. My motor before the blower would barely idle below 1100,and with the blower on it idles great at 900.
383's can rev to 8k if you build it right.
It really depends what your goals are,I'm not saying you can't run a 144 on a 383,people run 177's on bigblocks. It just sounds like you want to make a lot of power,and I don't think the 144 will do it. When its overdriven to flow alot of air the air gets hotter and it stops making anymore power.
If you want a street car that makes gobs of torque and really sets you back in your seat off idle,and runs smooth,and looks cool,then run the 144. If you want to lay down the big numbers on the track and dyno I would go another route. I see those things sell used on ebay for only a few hundred under the cost new.
You kinda gotta look at that blower as you would a 50-70 shot of nitrous,cause thats about how much power they are worth. I figure my 177 is worth the same as a 100 shot,but I got no bottle to refill.
