I'd like to flow my heads to see what's going on in there.
I have flat top Ross pistons and the heads are still 63cc.

Been thinking about a bigger carb. 850 or 950 E85. Any thoughts on that.

Small clean up on Indy heads, how small? 
They are not good out of the box and a small clean up wont make for a good set of heads.
Sounds like its time for some porting. 

Either carb would work well. The 950 may print a better dyno number but not make the car faster. 
I would go with a 950 if you have any plans of porting, may not be ideal now but will  be better with ported heads.

I can't help but notice that when you were forced to short shift it that your e.t's improved,  I have realized over the years that lower shift points have improved many friend's e.t's as well.Is it possible that you are just simply shifting out of the power band?

Shifting beyond the breathing point of the heads. Has the cam been dialed in? With the E85 I would test advancing the cam about 3 degrees so the power band turns on sooner or if you continue the higher RPM shifting, retard the cam and test for ping with more advanced timing.

Hi guys, been busy so I haven't been on the forum for a while. Just got back from Rock Falls Raceway with my best run at 11.25 @ 116.7 mph. That's my all time record now. I looked at my tac just before the finish and it read 6000. My motor hp dropped off at 6200 on the dyno. I have 4.10 gears and 27.3" tires. I'm thinking I'm running out of gear. Also my 60 foot is 1.52. What do you guys think on changing to 3.73 gears? My mph just seems lopsided compared to other cars at the track that were more mph and less ET.??
You are probably pushing way to much air from the 500 ft. to the 1320 ft. mark. car is to high in air, and air is getting caught under car and acting like a parachute, lower car as much as possible. and maybe a air dam on front, stop as much as possible, my Spirit is 5 inches off ground and my frt coil overs are adjusted as low, as possible, when I did that I picked up 3 mph in 1/8 mi.

OK, new plan what do you think. I'm pulling my motor this weekend. Taking apart for some oil leak issues.
I'm bringing my SR401 heads down to Minneapolis (R&R performance)these guys get some numbers out of heads, they got 305 out of a set of 291C's for my friends 401. I have $1200.00 saved just for head work. Want to get heads milled down also to make 12.5 to 1 compression, right now they are 63CC and they are supposed to be able to go to 49CC.
Was thinking too about Quick fuel Q-series 1050/4150.
I don't want to change the cam though as it is real streetable and will still yank the wheels in my driveway.
Any thoughts?
