I just got back from the machine shop so I asked about it while I was there.
I asked about the heads and he said there would be NO problem getting 330HP and still pass Smog testing. He's an old time Chebie racer from the Trans-Am days so he's built some horsepower in his time.:)
If my...
How much can we do before emission testing becomes an issue. I know hotter cams cause problems, how about the heads. Will aftermarket heads with a similar chamber size but larger valves be beneficial without penalty?
Is it principally the heads making the 81 the lowest HP Vette ever?
After a carb failure last week I've developed an engine knock. I'm assuming a lot of raw fuel was dumped into the sump diluting the oil. I had the oil changed on the weekend to be safe but apparently too late. On the way to work Monday a knock developed at 2000 RPM and by the time I arrived it...
Not entirely true. The thermostat represents a restriction so enhanced flow potential could well "pile up" water behind the T-stat raising water pressure.
The higher water pressure resists the formation of micro bubbles at the head/water interface allowing better heat transfer longer. Like a...
Not so much the flow volume but pressure would be my interest. Will the high flow pump raise block pressure to inhibit microboiling in the desert summer?
If I may digress slightly,
I've heard I can ditch the ECM just by replacing the distributor with an earlier model. Apparently not true if the fuel level is being adjusted in the carb???;help
Actually, it was your thread that got me motivated:) I started looking for the orange wire. Sadly ALL of mine are black but we found it in the end.
Thanx for the link and thanx for the motivation. And LLC5, thanx for the point of search.
This Forum is awesome:D
Yow! Thanx!
Found it and reconnected it already. Much appreciated.
The gauge reads zero instead of pegged now but I'll deal with that later.
Again, Thanx...
Hi guys,
Is there room for a stupid question here? Hope so cuz it's all I've got:)
The pressure gauge on my 81 is cosistently pegged. I've looked at the archives and under the hood. Too much oily wiring to spot an orange wire in that mess.
Is the oil pressure gauge sender unit a two...
I live in the Mojave desert. Last year I got a job requiring 60 miles a day of open road high speed driving. The poor ol' 81 couldn't cope so I had to buy a new rad.
Turned out the AC equipped Vette had a standard rad when a heavy duty was available. After bringing home the standard and...
So to turn this same question upside down, for my daily driver, would I enjoy benefits of a 383 stroker or would it introduce other issues. For example, sorting the carburation and spark. Would the stock computer be tossed? Would I pass emissions easier or more difficult?
How long IS that...
Which manifold would be an improvement without compromising the Smog check? My old Jag beats the pants off my 81 and that's just not right. How much can I do and still pass Smog reliably?
