Fuel injection did have an effect on the power of the engines. I have two friends, one works for Hendricks and the other for Roush Racing.
The both said the NASCAR engines still make more power with carbs and accelerate better during transient acceleration when compared to fuel injection.

Holley must have paid a big fee to be the sole supplier of the FI components.
The MOTEC system would have been better.

I am sure there was money involved, but having one supplier and a rigid set of rules and parts, this will save the teams money and will be easier to monitor for tech.

They've had spec ignition boxes for years. No big deal.

Can't wait to see them with the flat hoods. They will look like super stock on steroids.

This is going to be interesting design wise. The rules say the air intake must be between the hood and grill. 500 cubes spinning 10,500 rpm gotta pull it from somewhere. Where will that be? Wide low profile radiators to fit an intake above it?

Probably a pan like P/ST used to use. It was a huge thing that drew air from the grille.

Applaud the loss of scoops but if fenders and hood are still "bubble up" , not so good
Prolly can't change that profile....looking forward to some chassis action on the leave however

Gotta feel for the carb suppliers

No Big money involved lol, well maybe time spent giving technical support to the teams as they become familiar with the system.
Holley was already a contingency sponsor in Pro Stock. That will continue.
