1995 Silverado 1/2 350->1995 454 TBI swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello everyone, I'd like to thank everyone in advanced for any help they can give,

I'm looking on buying a used 1995 454 TBI for my 95 Silverado which has a 350 with 290,000 miles. The 454 is complete, serpentine system manifolds, TBI intake and heads, wiring harness and computer, pretty much plug and play. Here are my questions however before I go ahead and buy the motor.

Are the frame mounts going to be the same for the 454?

I read the 4L60E and the 4L80E have the same bolt pattern, so they should bolt up fine; but will the PCM need to be flashed and reprogrammed for the 4L60E anyways?

1/2 Tie-rod front end suspension enough for the heavy 454?

Any other issues that I've missed that I should think about?

How many tires will I burn off!

Thanks

-Paul
