Ok so I have a 460 engine that was supposed to be rebuilt and I decided to tear into the engine and replace the following with these parts edelbrock preformer cam, and preformer intake manifold, edelbrock 750 cfm carb, edelbrock fuel pump, edelbrock timming chain, new lifters, and rocker arms, heads redone, new headers and exhuast system etc... and edelbrock tech told me I needed to change out my rear gear ratio with a 4.10 and I will have to re calibrate the speedo speedometer so here are some of my questions...

Please keep in mnd this is my first top end engine rebuild, and my plan is to have a street/strip type truck just want some decent speed trying to reach atleast 350 hp,, not looking to pull or haul with this truck it is beeing repainted and chromed out to be a head turner!!!!!

1. where is the speedo spedometer on the truck...
2. how hard will it be to change out those rear gears....
3. What automatic transmission would you recommend if you were going to replace it I believe it has factory trans c6..

Please all other adise is welcome and help with advise on when I put parts back on things i should not forget that are critical will be very appreciated!!

You won't need rear gears changed if you run the performer cam and intake.

This cam is very small for a 460 inch engine I think it is like 204 @ .050. That's small for a small block.

Your combination of parts will run well, but you could have spent less money and made more power where you are wanting it.

You don't say what your current gear ratio or tire size is - but from the picture it looks like your tires are around 30" to 31" tall and if your gear ratio is around 3.54 you are fine. 4.10 gearing is about right for 33" to 35" tires. I have 4.56 gears with 37" tires which puts my cruise rpm around 2,500.
