i'd say you should be close to 380ish

Run it at the track! Who gives a **** what it dynoes, my LT1 has a cold air, borla and set of Hooker LTs with a Vigi 3200 stall I only put down 260rwhp/285rwtq, the car still ran a 12.8@102 on drag radials, stock 3.23 gears and heavy *** WS6s up front. Most dyno numbers are based off these six speed 10 bolt cars any way. Go run it and get some ETs, those are the best indicators on the set up dyno numbers are worthless in a stalled auto.

I understand they might have good flow numbers, but there are alot of heads in the mustang world and fbodies that put down sick numbers on paper, but that doesnt matter because this is the real world...


Somthing isnt right

 

Track times are the real numbers, and the dyno helps you gauge what the car should be doing a bit....

Do you have a flow sheet or somthing like that to post up?

 

I'm waiting to get the heads back. With my old heads that flowed 240cfm and a 22x cam I went 118mph in the 1/4 in a full weight car though.

 

I dont have flow sheets yet, the car is getting another tune the end of this week, I'll have them up soon, stand ready

 

I have been thinking and I cant realistically wind my cam all the way up to 6800+ where it makes its peak power because of my stock bottom. Any other cams that come to mind that would be better for me guys? I dont know if I need this 108 LSA one..

 

my fuddle cam only car ran 12.0 auto do absorb power though, id say its the tune thats lacking the hp...

 

You can pickup another 15-20rwhp from the A/F tuning

 

Where is this blackstone located? same guy that did LJ's heads back in the day?

He know's his stuff from what i gather.. give him a call see what he say's...

 

You are correct. These heads were on a GM-High Tech cover car-LJ's. As another put it..These heads are the lungs for a fire breathing dragon..Thats why its depressing the results have been dissapointing as equivilent to cam only LT1 #'s..

 

yea i almost bought those back in the day... yea you def have something a miss in that combo.. who picked your cam out for ya? have you spoke to mike about what your trying to do with it? etc.. the cam can make or break your combo.. just know that your heads are no the problem!

 

The cam is a custom grind by Bauer FOR those heads. Its twisted because Im not winding my cam high enough to see the real power [stock shortblock], yet the guys dynoing my car said after 6800 it was still peaking but there didnt seem to be too much more left. I havent spoke to Mike yet.

 

Hmm interesting.. i def. don't recommend going above 6800 frequently.. on a stock bottom end.. i added a few window's in my oil pan going that high... you have a pic of the graph?

 

Stupid question, but... do you have an LT4 knock module?

 

not stupid... good question... but it dont take a LT4 Knock module to tune out the noise that roller rockers and what not make... it can be done through tuning.

 

I'de find a very reputable place that can dyno tune it then, get that a/f in check and the timing tuned in then run it at the track and see what it does.

 

No, Im not getting any false knock.

And I dont have the graphs yet my I am still going to get one more run, this time the A/F will be corrected and the car will be tuned better.

 

Oh, and I dont have the car shift at 6800, that was just done for the dyno purpose to find the peak power, its set at 6500 in 1st, 6400 2,3,4.

 

Welcome to the club. My LT1 loves to dissapoint also. Both at the track and on the dyno.
