Test fit my motor today... pics!

Well, I decided to swap in a 302 instead of the 460. I'm thinking the 302 swap will yield the results I'm after better than the 460 would. Some things of importance to me are budget built, fuel injection, decent mpg, (affordable) OD transmission, A/C, etc... none of which the 460 would deliver.

I'm such an idiot... I was pulling the 460 back out today and it wasn't able to come back out! I'm thinking "this thing went in a LOT easier than this!" Then I remember to take the water pump back off



And here are some pics from today...






5.0 AOD vs 4.0 A4LD(?)

I love these little carts... awesome for moving stuff around

Here's my big steel cart with a 460, C6, and NP205 on it

And here's that same cart with the 460/C6/NP205 and two 5.0 motors!

Here is the 460 and 302 next to each other

460!

I think you ought to be the first to do TWO 302's, inline.

defacto low gears



that 460 lookin like it needs some money anyway. too bad its not going in though.

That combined with the normal "bigger is better" thinking in picking parts gets you problems quickly. Depending on how you build the 460, as a minimum a 700-750 carb will work fine for most applications.

this is what i've found works best on mine...a 750 cfm holley 4150

As for running 3.08's, with the torque of a 460, you'll never notice the taller gearing from a dead stop in a relatively light vehicle. It'll light up the rear tires so easily, they'll (the spinning tires) will act as a de-facto lower gear ratio

while this really comes down to tire size,it's a good bet.i'm running 4.10 gears,but with 44'' tires.it has a good highway ratio,and good off-the-line performance...and that was with the c6 in it.

yah,it is too bad.but as for the money,460s all look like that.unlike a smallblock,that isn't neccesarilly a sign it's worn out.i've found it's rare they've been used anywhere near their limit at any point during their normal(pre-goon)life.

some degreaser and a can of spray paint,it'll be ready for a life of abuse.

Well... I've changed my mind... again... and gonna go with the 460! The money it would take to build my 302 to the same power as my stock 460 just isn't worth it. I'll throw a mild cam in it and call it good for now, then that leaves a lot of room for HP growth through the years.

What kind of problems have you had with a carb ? Most who do have problems with em, never take the time to understand what makes em work. That combined with the normal "bigger is better" thinking in picking parts gets you problems quickly. Depending on how you build the 460, as a minimum a 700-750 carb will work fine for most applications. Bigger isn't always better when picking a carb. It's not EFI, where the fuel is injected into the air stream. A carb depends on the pressure differential between the intake and aircleaner (otherwise known as vacuum) to draw the fuel from the bowls. The bigger the carb, the lower the vacuum signal you have to work with. So a smaller carb responds quicker to the engine's demands. As for running 3.08's, with the torque of a 460, you'll never notice the taller gearing from a dead stop in a relatively light vehicle. It'll light up the rear tires so easily, they'll (the spinning tires) will act as a de-facto lower gear ratio

Rereading some old threads and I see I've never addressed this post. As you said, I simply don't understand how they work, nor do I know how to tune or rebuild one. I plan to use the carb that came with the motor, which is a Carter 750 that looks fairly new, or at least not used much. This may not be the best carb, but it's what I have, so I'd like to use it.

Thanks for explaining the basic operating principles of a carb. I never knew the carb drew fuel in because of vacuum... just figured it was pressurized and forced in that way. Hopefully I learn a lot by doing this swap.
