Debunking Crate Engine Myths with Chevrolet Product Manager James Bloss
Published by Crate Insider on 12th Dec 2024
Rumors have been swirling around the racing community about Chevrolet Performance possibly stopping production of their legendary racing crate engines for years. To set the record straight, we sat down with James Bloss, Product Manager of the Performance Parts Division at Chevrolet Performance. In this exclusive interview, James not only shuts down the rumors but provides a behind-the-scenes look at what’s really happening with Chevrolet Performance’s production. Here’s what we learned.
Q: James, can you introduce yourself and your role at Chevrolet Performance?
James Bloss: Sure, Kate! I’ve been with Chevrolet Performance for over 13 years. My journey began as an ASE technician, and I’m still ASE Master Certified. I’m hands-on with my own racecars, hot rods, and family vehicles, blending technical expertise with business skills as a Product Manager. A fun side note: I’ve grown a beard to play Santa Claus at an upcoming party, so feel free to call me Santa James Bloss for now!
Q: Is Chevrolet Performance planning to continue producing the 602, 604, and CT 525 crate engines?
James Bloss: Absolutely! Chevrolet Performance remains fully committed to this space. Right now, we have over 400 CT 350s, 156 604s, and 100 CT 525 engines in stock. We also introduced a CT 525 racing long block last year, customizable for various sanctioning bodies. We’re here to stay and dedicated to supporting our racers.
Q: How are you addressing supply chain challenges, and what can racers expect for 2025?
James Bloss: Supply chain issues have been a challenge, especially for small-block 350 components that are over 50 years old. When suppliers want to exit the business, we must resource parts, which takes 6-12 months due to our strict validation processes. We’ve improved our systems to anticipate shortages earlier and have completed or are finalizing many resourcing efforts. For 2025, racers can expect more consistent availability of engines and parts.
Q: Have the recent changes to cylinder heads on the 602 and 604 engines impacted performance?
James Bloss: Not at all. The 604 hasn’t seen any changes in over five years. For the 602, the only modification has been switching from a press-in stud to a screw-in stud. This change improves reliability without affecting performance and helps keep pricing stable.
Q: Prices for engines and parts have increased significantly. Does this signal Chevrolet Performance exiting the market?
James Bloss: Not at all. The price increases reflect the shift to domestic production and rising material costs. Moving manufacturing back to the U.S. improved quality—our blocks and heads are now CNC-machined for tighter tolerances. Chevrolet Performance is here to stay, committed to providing top-quality products for racers.
Q: Any closing thoughts for the racing community?
James Bloss: Chevrolet Performance is deeply committed to the racing market. We’re launching initiatives like a new Chevrolet Performance website that showcases our portfolio for hot rodding, drag racing, and circle track racing. I’m personally invested in this role and look forward to supporting the racing community for years to come.
Chevrolet Performance continues to demonstrate its commitment to the racing community. From maintaining engine production to addressing supply chain challenges, the company ensures racers have access to the reliable parts and engines they need.
