Chevrolet 632 Big Block Nitrous Engine

The engine of the week is presented by

One of the coolest running events we got to take part in last summer was Joe Zolper’s The fight of the builders – a race where builders competed against each other for skill, labor and knowledge rather than those with the deepest pockets. All entrants had to go through a selection process to qualify as a builder to be part of this race, having to convince a panel of five that they qualify as a builder by building their own engine (no job machine), building their own chassis or cage, or building their car from scratch. They also had to be the driver.

Simply wiring or plumbing your car, installing an engine, installing wheels, or bolting on suspension parts did not qualify you as a builder in this race. For those who passed, participants competed in one of five classes – Big Tire, Small Tire, 4.50 Index, Daily Driver and High 5. Only the Daily Driver class was exempt from the requirement to qualify as a manufacturer and was open to all vehicles.

We loved the old-school concept of this new race, so we flew to St. Louis to spend a few days at World Wide Technology Raceway in Madison, IL. One of the first competitors we saw on the track was Mike McCoy. Mike showed up with a 1966 Chevy II Nova and a 632 big-block Chevrolet nitrous engine under the hood. The drag race was 1/8th of a mile and Mike was racing in the High 5 class.

Admittedly, Mike told us that he intended to bring his Funny car, which he also works on a lot, but when he couldn’t be ready in time, he opted for the Nova. Mike also mentioned that he was not an engine specialist, but had worked hard on the transmission and the car itself in order to qualify. As for its engine, it relied on a BluePrint Engines 632 cubic inch big block Chevy package.

“It’s a checkout engine from BluePrint,” McCoy says. “BluePrint did everything for the engine. They do the heads, the block and select all the internals.

For those who don’t know, BluePrint Engines is located in Kearney, NE and was founded by Norris Marshall 40 years ago. Marshall started by building engines for local racers in his garage. Since then, BluePrint Engines has grown into one of the world’s largest crate engine manufacturers.

“If you add this engine to a streetcar, it comes with a warranty,” McCoy pointed out. “It works well for parenthesis racing and the grudge stuff we do, even with our car weighing 2,950 lbs. with me in it. It runs 6 seconds on pump gas, which is pretty good power with 11:1 compression and a hydraulic roller cam.

Besides what BluePrint supplied, we put everything else on the engine, like the alternator, water pump, manifolds, Edelbrock intake, Holley carburetor and MSD ignition. We also got a shot of Induction Solutions 100 horsepower nitrous to give us that extra boost if we need to get into the top 5s. The engine generally runs fairly smoothly. It is an energy generator to run on gasoline from the pump.

McCoy’s Chevy II Nova also features an integrated transmission, which McCoy played a significant role in, as well as a 7.50 cert cage and lettering on the side of the car from Racer Tees that reads “Orange Blossom Special”. No matter what happened on the track, McCoy told us he was happy to be at the Builder’s Brawl and was looking to have a good time.

“I had done a few of the No Prep Kings races before Joe started the Builder’s Brawl,” he says. “That’s where I met Joe and became friends with him on Facebook. He started Builder’s Brawl and I liked the idea of ​​having a race where you have to do a lot of the work yourself. Joe is a stand up guy and I love what he stands for – if you built it, bring it, run it, and we’ll see where you fall. I am here to have fun.

McCoy’s 632 big-block Chevy is capable of 840 NA horsepower at the gas pump, giving it a low 6-in-eight capability. Looking to run 5.75 to 5.80 and compete in the High 5 class, McCoy would use that 100 hp shot of nitrous to get there. These 940 horsepower and some 100 octane fuels should do the trick!
