Hi
question from a newbie v8 owner....
I've just bought a Corvette 59 -283cui with a torker intake, camel hump heads, holley 650 double pumper, and some sort of performance cam with a TH400 with a shift kit.
Engine idle is quite lopey, and when ever I put the car in drive, it will drop in rpm until it dies!
Only way to keep it alive is to do some "two foot" driving, one for braking and one for accelerating.
The missus is not particularly happy with this :spank: , so I need to improve the situation, so that she can cruise with her friends...
Now if the timing, carb, vauum leaks, checks out OK (I have done some search...), what then?
can it be that the stall speed of the converter is too low, and combined with the cam, the 283 is "overloaded" when idling and put in drive?
Sorry, havent checked the stall, the tach drive i broken...
Is the 400 simply too big for the 283?
Unless it idles quite low , it'll engage drive quite hard, and I think that it does move quite a lot, considering the low idle speed....
carb question:
I'm planning to install a Street Avenger, most likely the 570, from the point of not overdoing it.
In case I would be overhauling the engine to a 327 (engine block is a # 3789817, so I take it should not be a problem) would it be better to look at the 670?
Having sniffed around a bit, I found that I would need some 570cfm with a 327 at 7000rpm with VE85%.
Since I'm not racing a lot, but more the cruising type, with an occational pull, it seems that the 570 would be a wise choice.
Any comments appreciated, - especially for the first part....
thx
