What did @blite903 actually say?
The creator laid out a specific parts list for hitting 400 wheel horsepower on a Dodge Charger, Challenger, or R/T. The list includes a JLT cold air intake, a 90mm throttle body, long tube headers, a Texas Speed stage 4 cam kit, a ProFlex E85 conversion kit, and a custom dyno tune. The claimed total: "right at $3,000." That's a tight budget for a cam swap build, and the number deserves scrutiny.
This is a car modification video, not a health or hormone therapy video. The TRT category tag on this content appears to be a misclassification. Nothing in the transcript relates to testosterone replacement therapy, hypogonadism, or any medical topic. This fact-check will evaluate the automotive claims on their own merits.
Does the evidence back this up?
The parts combination is legitimate and widely used in the Mopar community. Cold air intakes, larger throttle bodies, long tube headers, and camshaft upgrades are all documented power adders on 5.7L and 6.4L HEMI engines. The E85 conversion adds fuel delivery capability that pairs well with aggressive camshaft timing. The 400whp target is achievable, but the $3,000 estimate is where things get shaky.
Texas Speed and Performance's stage 4 cam kits for HEMI applications run roughly $800-$1,100 depending on lifter packages. ProFlex Commander kits typically cost $500-$700. JLT intakes and 90mm throttle bodies add another $300-$500 combined. Long tube headers for HEMI platforms, particularly mid-length or true long tubes, run $600-$1,500 depending on brand and port matching. A custom dyno tune from a reputable shop usually costs $400-$800. Add gaskets, seals, and labor, and $3,000 covers parts only if you're doing the work yourself and finding deals. Professional installation easily doubles or triples the total cost.
What did they get wrong, or right?
The parts selection is genuinely solid advice. These are not random bolt-ons. Cam swaps on pushrod HEMI engines respond well to supporting modifications like improved airflow and fuel quality, and the ProFlex E85 system is a well-regarded solution for flex fuel capability without a full standalone tune. Credit where it's due: this is a coherent, internally consistent build plan.
The $3,000 figure is the problem. It appears to cover parts only, with no mention of labor costs for what is a moderately complex engine build. A cam swap on a HEMI requires removing the intake manifold, timing cover, and in many cases the engine from the vehicle depending on shop preference. Labor alone can run $1,500-$3,000 at a competent shop. The video does not clarify whether $3,000 is parts-only or all-in. That omission will mislead viewers who don't already know what a cam swap entails. The 400whp number is plausible on a 5.7L with these mods on E85, though it's more reliably achieved on the 6.4L platform.
What should you actually know?
If you're planning this build, budget conservatively. Parts alone will likely run $2,500-$4,500 depending on brand choices, and professional labor adds significantly to that. The 400whp target is realistic on a 6.4L HEMI with E85 and a proper tune. On a stock 5.7L, you may land closer to 370-390whp depending on cam selection and engine condition. Also worth noting: long tube headers may affect emissions compliance and could cause a check engine light without appropriate oxygen sensor management.
The E85 conversion requires consistent access to E85 fuel. In areas where E85 availability is limited, the ProFlex system's adaptive tuning helps, but peak power figures quoted by builders typically assume full E85. On pump gas, expect noticeably less output. The dyno tune is non-negotiable in this build. Running an aggressive cam on E85 without a proper tune is not a cost-saving measure, it's an engine-damaging one.
