300BHP and I have no problem, like me, sometimes I belive what he means to convey, and the general air of what he DOES convey differ. Yes, he did PM me and was as helpful as someone could be not seeing the car themself.

There is no comparison between GT40 heads and a box stock any brand aluminum head.
the difference is your car struggling to run low to mid 13's with the Gt40's and your car running very easy mid to high 12's with aluminums.
to each there own. just my .02 cents. it seems like your focused on wanting to beat stock LS1's good luck and I really hope that carb helps I would really like to see how fast you can get your car on the GT40's.

Of course, 4.10's are NOT stock, and it was your goal to beat a factory stock LS1 car. So kudos if you can pull that off after you get everything running right.

I agree 100%, alum. heads rock, but the engine came nice and purdy in its crate with a 345bhp/345 tq rating. That is 20# more tq and the SAME hp as the ford engines have, according to dyno's of similar motors they are the same pretty much. Anywho....
The carb should be on in 2 weeks max.
Thankyou for the interest
4.10's and an LS1....hrmmm, I take your point, but wouldnt it suprise you to know that a stock 05/6 GT with 4.30's and a manual will trap as fast as some of the non-freak LS1 cars?

You can put 10 carbs or whatever on a turd but its still a turd. LOL. Im just messing with you. I dont think your car is a turd. You say this carb swap is going to knock 7 tenths off your 1/4. I will believe it when I see it.

I have a vid from JMS running 4.30's, Street ET's, CAI and their performance chip (tune).
12.43 @ 107mph
Nice ET but a well driven M6 Fbody should be 107-109mph range.

what? are you saying that the GT40's will make as much power as aluminum heads?
I dont understand your post.

Yes, my GT40p's make as much hp as out of the box GT40 aluminum swirl heads.
THey are 1.5pnts higher in compression, according to the 5.0 ford manual someone actually figured out that ever .5 in compression raise equates to 15 bhp, so while they dont flow as well, they have a LOT more compression going for them and that is the great equalizer, plus the flow velocity is KILLER! on these heads. They flow 200 CFM through 1.84 intake valves. THat is compared to a 2.02 and 225 cfm or so. (figures at .550 lift).
At any rate, the combo should lay down just south of 300whp and I am desperately hunting answers, carb tuner swears my secondaries dont open--im buying a DP, SHOULD! fix it. We will see.

I wouldnt compare them to gt40 swirls though, they arent the only aluminum head out there. IMHO, on a mild modded car, a good aluminum head set and a cam is equal to performance with a blower under 8 or 9 lbs.

......
^no arguments there, but gears alone get you a 103ish trap and thats up from 99 normally. Not bad for a single mod...

I agree ram rod. At any rate, heads,cam,full bolt-ons appear to have done nothing over stock for my car. But I will bolt the other carb on and see if it makes a difference

I guess you are right, all my cylinders fire and they all have compression, a dead cylinder is the only in-motor thing that could cause this pretty much. I suppose you have a point. I will know Friday when I bolt on the 600DP.

I hope so, he picked it out over the phone, then drove it around the block andsaid he was 99% sure, then I found a site saying with the spring I have, it takes until 5700 rpm on a 350 with no air filter to fully open the secondaries...I have a 302 WITH an air filter...I dont think they are really coming open.

I am awaiting to see if this buildup can break mid 13's.
