just curious about this change
 

I have a 2500 pond car with me in it that ran best of 10.26
383 sbc.....victor jr heads 215cc intake runners........comp cam roller solid .650 lift....268-272 duration......850 hp4150 carb....hurricane intake ported..... 1 inch phenolic spacer.......1 3/4 headers open......12.5 pistons......powerglide 8 inch 5300 stall......5.14 gears and 32x14x15 slicks....i ordered the new afr elimnators competetion heads that r 210cc intake runners and flow 311cfm @>700.the old heads may flow 285 cfm..........how much hp will i gain and what kinda times could i expect....hopefully in the nines.maybe 9.99.......thanks

From the numbers that you give I come up with a new time of 10.11 ET. But I was off .06 on guessing Brain's numbers so its just in the ball park.

hy dyno operator, if a motor is dynoed closer to sea level, does that meen its more acurate to the numbers than when its been corrected?

I was told by a performance company that putting these new heads on compared to the old ones and the carb is getting dynoed(flow tested) by him and also setting the ladder bar down to the bottom hole from the middle i would gain around 4/10 th do u guys agree......thanks

I would say that a 4/10th statement could be true because a fine tuned package can make all the diffance in the world. If the chassis is not right then you can pick up some time there if the carb is not right you can pick up time there an you can always pick up time with a better flowing head for a complete combo. So is it possible to get 4/10th from a fine tuned package I would say so.

anbody else want to put in there input........thanks

Why is he recommending you drop the ladder bars one hole?

If the car hooks like it appears to be in your avatar why would you mess with the suspension? :?

well i will tell you what i have been told by some very knowledgable men...my intake team "g" IS NOT WORTH A CUSS...i have a great set of heads (ported brodix)..but they are not doing me 100% what they are designed to do with my current intake..
same with you..i am not famailer with a hurricane intake..but i can tell you from a common sense stand point..if your intake is not up to snuff. your heads will not stand as tall as they should.

I'll just say flow #'s arent everything,
I've used the hurricane intake before and had good luck with it, I think you'll see some gain .10 I wouldnt change the ladder bar holes though, looks to be working well already.
