I would say thats pretty good for a IMO smaller cam and little header?
We will be going to a 1 7/8 w/Merge Collectors over the winter just to see what its worth?

Guess the ole out of the box Darts arent too bad :D

[SStrokerAce]

Told ya those heads aren't bad!

[wkmcd]

Nice numbers!!! Congrats.

Can you post up a graph?

[JS1965]

Bret I can only imagine how much better your Darts are..
Its something we might find out over the winter ;)
I'll get a graph up real soon

[SStrokerAce]

I'd like to see a chart as well....

A set of prepped Darts on there would be a cool deal!

[willyfastz]

That's some dang nice #'s for that setup, congrats.



I have several customer cars with Brets darts on them and they're very impressive indeed.

[JS1965]

These are out of the box,Bret hasnt touched them
He MIGHT get them over the winter ;)

Yeah I read that, I 've done a few cars with them straight out of the box (plus good springs) and they did pretty good.

And that's deff good #'s for Pacesetter headers also. What kind of dyno was it on? I think my dyno is stingy compared to a lot of others.

[JS1965]
