The first car he brought me was a blue 69 with a big block 427 with an epoxy up big port intake on oval port heads......so I replaced the heads and cam with an eddy top end kit with a roller cam upgrade and some side mount headers.
I played with the exhaust baffles on this car also and it turned out pretty good....or at least I do and the owner.
The next car was the 68 small block that I rebuilt the th 400 trans and did a eddy top end kit.....but it was a low compression truck block so I installed LT 1 forged pistons....This truck block was so virgin it had no wear on the plastic cam gear or cylinders.
The funny thing was that both of these other car didn't have vet engines in them and he always wondered how many he had to buy to get one with a vet engine......guess what this 76 had the original engine in it...go figure.
