V8 vs V6 (Page 2/9)
treborerellim DEC 21, 08:20 PM
The reason I went with the Cadillac V8 first place is I ran into a guy that had a 4.9 hooked up to a 4T60 transmission that decided he wanted to go with a Chevy V8 instead and I picked it up for $250. The guy that did the wiring job suggested I order have a 46 t e would be a better way2go and I happened to pick one out of a Cadillac Eldorado engine and trans for 150 dollars. But I can't seem to get all the bugs out of it. As to what suggestion Dennis made in the second paragraph I think you wrote it in Greek, because I don't have a clue on how to do any of it. I guess I'll have to find somebody that really knows what he's doing that can diagnose the problems and correct them. That'll probably cost me a ton of money.

I received a lot of good information and really appreciate all the responses. I kind of doubt I'm going to put my other Cadillac engine in my 87 GT and will probably keep it a V6 as I have 2 V6s laying around and another five speed trans.

Think about a four cylinder. My LNF, very mildly tuned - at wheels = 325 whp 347 Tq 2 liter modern engine, lots of room around it. Biggest issue is finding a place to put the intercooler.



Exactly, but that's turbo. It's a different breed. I could make over 400WHP with the 2.8L if I turbo it. Turbos are for individuals who don't know how to make power Naturally Aspirated.

No, turbos are for when you run out of improvements on a naturally aspirated engine and still want more. Big power in smaller package with better fuel mileage.

I see your point and makes lots of sense. In my case I'm always trying to come up with improvements for that same reason, not using a turbo.

A turbo kind of stops you from thinking out of the box because now you have no limits. But if you limit yourself to non turbo then the your creativity grows. You see how a turbo hinders creativity?

That's the mistake that lots of people do, call out torque figures but not at a specific RPM.


Electric vehicles have little horsepower but full torque starting at 1 RPM and holding thru the RPM range. They are quite good performers with usually fast acceleration. Torque always matters.

The more bottom end torque available directly results in acceleration off of the line.

Torque = Acceleration

Horsepower = Top end

Exactly!!
If Torque = Work and HP = How fast that work is being delivered, the higher in the RPM range you can locate that Torque the more acceleration you are going to have. Because you are increasing the rate/speed of the applied torque/work.

I Googled both hijack and tangent and I think my thread qualifies for both. Just saying
