dyno results with the Trick Flows
I have now got this motor making the power I've been looking for for several years. My previous dyno runs were disappointing at best. With the S/R Torquer heads, comp cams 282S, and Torker II, I only was able to pull 238rwhp/296rwtq. Since then, I switched to the Trick flows, TeamG intake, and did a few minor things such as installing ultraflow mufflers and milling the choke tower on the Holley. If I had to guess before the run, I would have figured on slight improvment at about 270rwhp. Nope! Today's dyno run produced 308rwhp/316rwtq 
No one was more surprised than me. What a difference a good set of heads make. The torque curve is amazingly flat and stays near peak torque well past 5000rpms. I think I'll leave it alone now and just drive it. Here's a link to the dyno graph.........dyno run

Sweet numbers. That is what I was hoping to get out of mine when I went to the dyno. I only made 252 HP. I have been wanting to get a Performer RPM for mine to see if it would help. I have the XE262 so I think I would be pressed for those kind of numbers that you got. Congrats on a nice gain.
BTW, did you use the same dyno that you did on the first pull?

Really awesome man. Now I'm in the same spot you were a while back. Trying to figure out how much power I'm gonna get out of tuning the carb. Think the secondaries are rich...
...what about electric fans? what about X? what about y?
I'm ready to sell the Corvette and buy an LT4. Headers taking you to 322 rwhp! Nutty!

Looks like you got that dialled in, did they tune it for you or did you just do a few pulls ? That's an impressive torque curve nice and flat

Eddie,It was the same dyno place as last time.
Motorhead, This was just pulls only. Tuning was done by me by reading plugs and borrowing Steve's Gtech . I have to admit that I did not think this cam would make that much power until I saw yours put up those kind of numbers with your other "little" motor.
Steve, I get the feeling your gonna get hooked on this dyno thing. With your motor running that rich, I think you have alot of power waiting to be unleashed. Your a hell of alot closer than I was 2 years ago. Those 0-60 times are proof of that.

Great value in those TrickFlows.
Nice to see a direct bolt-on head that makes such a big inprovement. As i consider the WP torquers an improvement over stock Chevy heads. The TFs made more pwr by 2.5K rpm and never looked back. Those heads are priced right too.
Nice combo.

Tom,
Just saw your post after posting to Pacin's.
CONGRATULATIONS!!
Great to see it is finally running like it should. Linkage problems show up in some of the most unexpected ways. Glad you found this one after all your work with heads and intake. Too much work to have such a small gain from the previous setup.
Maybe by January or February I can start playing with Corvettes again. The past month has been ridiculous!
Miss you guys,
Chuck

I'm sure that you will feel 80 hp 
Your poor rear tires! Is that the same Team G as mine? something like a 7531 or 7532..... I can't ever remember the numbers.
Tom don't let those young guy's like Steve beat you!

If Steve starts catching up with me, I'll just have to vollunteer to help him with some carb work! Does anyone know where I can buy a restrictor plate for a Qjet? George, My intake is the 7525. I had considered the 7531, but those runners would probably be overkill for my combo. Traction is surprisingly good. I guess that means I need more power
I didn't think that your original numbers were all that bad, but these are spectacular.
Nicely done.

Matt, I do have a problem with A/F as you mentioned. It was pinging like crazy at the begining of that run. I started the next run at 2500 and no more pinging, but the readout still indicated some lean condition on that run too. I'm thinking I may need a bigger pump shot on the secondaries. What do you guys think? Alos, Is it possible to have a delay in the power curcuit?

After talking to Matt I went up to a 8.5 PV. I have since down graded to a 7.5 I think that most dyno runs are long enough in seconds to be past the squirt affecting A/F I'd go fatter on the secondaries.
Modern high swirl heads require less total timing than the old days. Dart told me to only use 32 degrees to make max HP at sea level. Since your pinging right off the hit of the throttle at less than 2500 rpm I would look at your advance system. I sent my Unilite back to Mallory and had them recourve it to 18 degrees mech advance. Because I'm at altitude I run a couple of extra degrees. So I have initial of 16 + 18 mech. = 34 I also have vacuum advance adjustable pot set to 4 degrees hooked to ported vacuum. All in at 3000 rpm.

As for timing, this motor never pings normally. Once I get the A/F worked out, I think the curve I'm running will be fine. Right now I'm running 16init + 20mech(no vac) with full adv between 2000-2500rpm.
Maybe this will help some believe that *some* single plane intakes really can be used on street cars.
Just like the "solid cams require constant lash adjustments" argument. And yes, the world is still flat.
