Lets talk about what makes this matchup fun.

To start, Both cars are stated 302 cubic inches.
Both will run with respective 350 NHRA Rated Combinations.

Daren's is a 2023 with the LT1 DI head running with Port Injection
My CJ can be either a 2013 or 2014 which is a 4 cam, 4 valve head Coyote engine.

Daren is running a Metric 200 Trans and Radial Tires
My car has a 5 speed G Force trans and I have bias tires

Daren says he has run a best of a 9.91 ET at a "high" DA Don't know how heavy he was but I think that he ran that in FS/F
My best ever with my car was a 10.11 with the 325 Combination. That was at the NMCA race in St Louis 2021. The DA was 1635' and with a 1.02 correction factor. I was 30 pounds over FS/H weight.

Daren says his engine makes 600 ish Horsepower at the crankshaft.on the Holley DTS Dyno. I haven't verified that but I think that is accurate.

I've played with my older 350 Combination and made the following numbers at the Crankshaft.

596 on First Engine I bought from Bo Butner on Holley Dyno back in 2017
615 on a Stuska with DEPAC at West Dyno near me 4 years ago
590 On current engine on Brian Wolfe's Superflow 901 2 years ago

As we know dyno's are relative. It's the track that counts.

Recent testing on the chassis dyno showed some promise with the intake and throttle body swap.

We have bantered about how close these combinations are to each other on paper.
This should be fun

Here are my current Rear Wheel Horsepower Numbers

The red line is my current 325 HP 2012 Setup with the stock intake and throttle body.
The blue line is a few days later with the Intake and throttle body for the 350 combination.

Enjoy
