That doesn’t sound like it looks. What’s in there?
It’s a GM Performance Parts 572ci, 620hp crate engine. But I’ve got a dyno sheet from an article in which these engines were tested, which shows them making 701hp. The company called GM and told them they had sent the wrong motor. But they hadn’t. Without admitting it in these words, GM just under-rates them, so that it doesn’t get caught out by the engine not making the claim and get sued. So they’re around 700hp and 935Nm of torque. But the carb that I’ve got on it must be worth about an extra 20hp; it makes a hell of a difference. It sure gets up and goes.
What gave you the idea of putting that motor into a vehicle that just looks like an old work truck?
I wasn’t going to buy a new vehicle, so figured I may as well buy a new motor. And Clive from AWFE suggested it. I was looking for a 502, but he said why don’t I go for the 572 instead. Go to the top of the range. So I did.
Any dramas with fitting it in there?
No, it bolts straight up ” to the original engine mounts and everything!
It’s pretty shiny in the engine bay. You’ve spent a bit of time in there.
Well, I changed the rocker covers, as when I open the bonnet at the gas station, I don’t really want people to know what it is. The stock covers are bright orange with 572 written on them. But now it looks like a standard big block. I’ve used the braided hoses for 30 years, not because it looks good but because they last.
What reaction does it get when it starts up? People must look twice.
Yes, they do. It scares the hell out of little old ladies and children in car-parks.
Have you got any plans to do anything to the exterior of the vehicle?
One day I’ll paint it. In the army green it’s got on it. I don’t want it too shiny, as I don’t want to have to be washing it or polishing it all the time. I can’t remember the last time I washed it.
