427 SB

[Nick]

A friend and I have been discussing his combo in his 63 chevy II. Its a 427 small block. Hes gone 11.02 @ 126 MPH and its a 3200lb car{with driver}
Heres a quick look at his combo...
-Dart IE block 10.5:1 compression
-227cc M2 track 1's
-box stock super victor
-850 annular mighty demon
-solid FT 312/312, 268/268@.050, .575/.575 Lift on a 108 Erson grind
-1 3/4" x3" fenderwell headers.
-He was running a carter mechenical 130 GPH fuel pump with -1/2" line running from the cell to the pump.
-4.33 gears and a tremec TKO 600.

Heres the thing. I think this motor should be making a LOT more power than it is. His jetting has been maxed at 93 front and 99 rear. and he still was showing very lean. Hes going to upgrade to the 172 GPH carter in hopes this will help the issue.

Now I have a few questions.
1. Is the super victor able to keep up with this motor out of the box or does it need porting? Would he pick up significantly from porting or should he go with a different intake?

2. Does he need more carb. Maybe a 1000cfm Race Demon? He dosent want to go with a dominator. This is a street/cruise car and he likes his gas mileage.

3. Are his headers a restriction? would 1 7/8 or 2" work better?

4. Woud there be alot of power to be found in a large solid roller setup and schubeck lifters?

5. Is he just running in circles trying the Carter fuel pump? Is this going to be enough?

I know this is alot of questions to ask at one shot but any and every opinion is appreciated.

Thanks, Nick

Out of the box Super Victor is plenty for a 10 sec. car, but some plenum work will help 10-20hp max. Super Victor is a very good intake.

Carb is ok, but I'd try a 950.

Anything over 1 3/4" on a motor like this will slow it down.

Roller cam will make more power with more agressive lobes, but I believe that the cam is the major problem with it, 10.5:1 and that big a cam... something smaller matched to the heads/car/comp. will make more power.

Carter 172 should be plenty.

Yea it should be faster, but it will take track tuning to get the mph up, cam should help big time.
What kinda exhaust?

[Nick]

The exaust is just home made cutouts and hes going to make an insert to make sure the gases all come out of the cutouts. 3 wing nuts and its off. The exaust stays on. Its because we drive to and from the track and try to make life as easy as possible once we're there.

So you think 1 3/4" primarys are just right? Not too small? The car likes to go past 6500 if thats a factor. I told him I would look to drop his advertised duration to somthing in the 290's and stay about the same @.050 on a split pattern, with as much lift as he could get on a 106 or 108. What would you suspect this motor makes peak power at?

126 MPH is plenty for a 10 second time slip . What 60 foot time's is the car running
