For some time I had been deliberating on what to do with the drivetrain in my 72' Chevelle. I am unhappy with the current set up, and had begun to remove it. At first I wanted to build a 468 BBC with TFS heads, a hyd roller cam, etc. And stick a TK600 5 speed behind it. Then I saw what that cost, plus thought about what a gas guzzler it would be. (I'm spolied, my 2001 Camaro SS gets 21-22 city and 27-28 highway)
So next, I felt I had 100% decided on a 2003-2007 GM truck LQ4 6.0 liter engine. Custom ground cam, ported heads, and a home built turbo set up with a 74mm turbo. But something tugged at me the entire time... it just didn't feel right to replace the big block with such an engine - even though it would make great power for less money. Part of me was really struggling with my descision.
I found myself online one night recently reading about the FAST and Factory Stock series of racing. I went to bed that night, barely able to sleep because the wheels were turning. Over the next few days, I began to look around my garage and dig through my father's garage. The 454 block I had was the correct casting #, and close enough in date code. My father has a set of exhaust manifolds, you guessed it... the correct casting # as well. He also had a set of new in the box Pypes 2.5" mandrel bent lead pipes to go with the manifolds. So my search began to procure the rest of the parts. Right then and there I decided to build a car that would be legal for the factory stock class. I will end up with a very correct/restored car that runs much better than "off the showroom floor." Last weekend I snagged the correct intake manifold, and a set of factory valver covers & timing cover. Today I was able to purchase the correct air cleaner assembly. A friend of my fathers has a 72' date coded points distributor he has decided to donate to me when he comes to visit in a few weeks for Thanksgiving. The rest of the combination will be to keep the 4 speed and clutch setup I currently have. I am going to trade 12 bolt rears with my father. He has a 2.73 open rear in his car, I have a 3.55 posi rear in mine. Then add a new Eaton posi and 4.10 gears to the rear I get from my father. I will also add new bearings at that time and look for some way to lighten up some parts without sacrificing strength.
I have a line on a set of cylinder heads, and a couple of carburetors. I expect to have them in my posession by this weekend. Everything is really comming together, I couldn't be happier at the moment.
I know, you are reading this and thinking - wait, what? Yes, this is a HUGE devation from what I originally intended. It will not make as much horsepower, or run as fast at the dragstrip. But, it has a certain cool factor for me. And I love it!
