if you where going for aroudn 450 rwhp N/A cam/heads and did a rebuild with it...what all problems would you run into if you drove it maybe 2 days a week? or is that not such a far fetched idea as far as driveability is concerned?

 

There's nothing that would prevent you from using it as a daily driver, as long as its put together using the correct parts, the correct assembly techniques and given the correct tune. Why would you be concerned about how many days a week you can drive it?

Probably a good question for "LT1 Engine Tech" since there are people on that forum who drive setups like this all the time..... moving post there.

 

ive never thought too much about n/a ive always been a boost fan, first car was a supercharged 3rd gen, any how, if u go for 450 rwhp ur gonna have to have a hell of a cam if im not mistaken, and with a hell of a cam ur gonna lose some of your driveability, vacuum etc, just lookin for any imput i can get on it

 

If you build a stroker you can make up for the loss of low end due to the big cam. Plus its going to be hard hitting 450hp on a stock displacement anyway...well not hard...but it would be easier to hit that # with a 383 IMO and certainly wouldnt' have the driveability issues.

 

Are you wanting 450 rear wheel HP or 450 crankshaft HP?

With a 383 you can do either and drive it everyday. (but the gas bill will be big)

 

thanks for the info, and btw, the optispark is good till what rpm?

 

450 rear wheel was the goal (prob gonna rebuild this winter)

 

Deffinitely an attainable goal, and certainly can be built to be a streetable combo.

 

Some have had the rotor come apart in the opti at 7000 rpm, I regularly see 6700 rpm in my car and its fine.

 

He indicated 450 rwhp, and its an M6. He needs to make about 515-520 flywheelHP. That's not a radical combo.

 

I drove mine everyday before twin turboing it. I was running 420rwhp. I had stock casting heads that were worked and a solidroller, but most people dont wanna run a solidroller. So to get to that goal it would have to be a pretty good build.
