I've been thinking of how I should put it to make you understand of how I see it.
If you'd had a chance to log the throttle position for a season on a street driven car (such as a 71 'Bee) I'd swear you never go WOT more than a few percent. Probably very very few.
The idle portion would be quite a big number, depending on the traffic situation at your location of course.
If I make a wild guess of the throttle opening you actually DRIVE your car I'd say it's mostly between idle and half throttle. At least that's how I drive my cars. Using a set of 275 BFG takes only a few minutes of pedaling! LOL
The engine I'm planning to build is for a driver.
Looking at dyno numbers are always fun, but I don't know anyone who puts his street car in gear, floors it from 2,500-3,000 and wait 'til the power ends. Well, if he goes to the track, but that's a completely different story.
A dyno can't give the information of how the engine works in a street car. How responsive it is, and what will happen if you give 3/4 throttle at 2,000 rpm's. A chassis dyno can do it better, but not fully.
I want my street driven 383 to be long lasting, ready for long trips on winding sideways or a trip to the town to lay out some smokescreens and no unburned fuel wiping off the oil film from the cylinder walls.
I want it to be snappy and happy, have muscle car characteristics with a bit lumpy idle and grunt from bottom so I don't have to wait for it to happen.
If it wouldn't have been a matching car I would have used the 67 440 I have sitting, or maybe built a 400 stroker. It would have made it easier to achieve my goals, but that's not an option now.
If I had too much money or lived in the US I would have considered building a stroker out of the matching block, but that's too risky with today's situation. Shipping overseas sucks these days...
As said before, a 383 is not the best start - but now it has to be a 383, and I will try to make the best of it.
I'm gonna try to use the parts I have and do it all by myself at home. Do it and build it someway I stated from the start. Be painstaking with the details, jetting and timing.
What I'm asking for is cam input from people who built something similar. Anyone?
Sincerely regards!
