Some good information going on here…

So, let’s drill down. Let me restate my questions and elaborate a bit:
1. Did you build the engine or have it built?
2. What pistons do you have
3. What is the deck height?
4. Why wasn’t the block decked?
5. Is your cam a stock Howards roller (like 120345-10) or a custom grind?

As to “where” you’re getting beat (Tech’s questions)
1. At the tree (hole shot)?
2. First 60 feet?
3. 330, 660 or top end?
4. What’s your RPM at the traps?

Couple other questions?
1. What is your 60 foot time?
2. What’s the 1/8 mile time
3. What’s the ¼ time and speed?
4. What transmission?
5. What converter (if automatic)?
6. Rear end type and ratio?
7. Tire size and type?

With the money you’ve spent I would certainly hope there is 650 (or more) horsepower at the flywheel and you should see mid to low 11’s all night long.

Keep the information coming and we can certainly help you dial this in.

Best,
Glenn

My cam was custom grind , and my block was decked ,and we ran out in country not on strip , I got 308 gears with low profile 17 inch nittos drag radials with no hop bars on rearend , he has same tires but he got a lot more side walls his is 15 tires and he got cow track bars I hop I'm saying that right he got 330 gears his is a 5 speed tremec transmission . Mind is a turbo 400 tranny , Lynn rays custom sped shop built my engine , I have Dyno sheet I will try to put it on here tonite. I have trouble hooking up. Also I got a Ambrose tq converter I might have spelled that wrong 3200 stall. He would out power me about the 1/8 mark an pull away. I got also a cfs carbuater I think 1060 cfm
