I picked up a set of Dart 225's from a fellow member here that I think is not going to work with what i'm doing. Stock bottom end, heads, mild cam, LT's, LS6 intake & ported tb.

My question is should I go with 195's, 205's or put the darts on? What are the pro & cons of using the darts?

Thanks,
Ron

 

Fast intake and BIG cam and it would rock up to 7K.

 

I guess I can go that route. But i'm not looking for anything radical. Just bump up the rwhp without going crazy. I want 360-380 rwhp. I have a Strange 12 bolt waiting to be dropped in w/373's. I'm just waiting for UMI to send the parts I ordered.

 

I dont see why they couldnt work. Most ported stock heads you get are about 225-230cc. Dart heads are very good heads and even better after a competent porter gets ahold of them. I would send a couple Pms and make a few phone calls to get yourself a 100% correct answer.

I would call TSP or Thunder racing and see what they say. I would think the heads would do well with a MS4 but your stock intake will limit you quite a bit.

 

I'm going to be putting on an LS6 intake. I can't wait until all the parts get here. Should I used my stock tb or get a bigger one? Port mine?

 

You might see a small gain from a ported throttle body. Not really worth it if you are going to upgrade shortly unless you find one cheap.
