I broke down and paid an engine builder to rebuild a 454 for me. Actually, everyone knows with me it couldn't be that simple to just drop off a motor and say "rebuild it". I brought him the 454 I had run in my Suburban for a few years. It was a longblock, .020 over with hypereutectic flattop pistons and 781 casting heads, and an Edelbrock cam that went flat. I brought him a used Comp 270 Hydraulic roller cam with lifters and valve springs and roller rockers to match out of another 454 I got that was in a friend's Blazer. Then the block I brought him showed more wear in the cylinders than he liked, so I brought him another 454 standard bore short block (my original first 454 I ever had that I put and ran in my GMC when I was 17) and he bored that block .020 over, using the flattop pistons and 781 heads from the 1st motor I brought him, and valvetrain from the other motor. In the end, I wound up with a freshly bored .020 over 454 with hypereutectic flattop pistons, 781 casting heads, a Comp 270 Hydraulic roller cam with .566 valve lift, roller rockers, and Edelbrock Performer intake for my '81 Crew Cab. I supplied all the parts and he did all the machine work, supplied rings and bearings and oil pump, rebuilt the heads, and assembled it as a long block ready to fire up and run for $800. Most I've spent on a motor outright, but at least it's done right... or done as right as possible while still being able to mix and match all my parts. Now I just need more storage space for engines... 4 complete 454s, 2 shortblock 454s and two complete 350s are now occupying the breezeway.
