And trans. I see a lot of people running big double pumpers on these small displacement small blocks.Compression ratio and cam specs please!!!!
TIA

I believe compression was 10.5:1. It’s 3:30 in the morning and I’m trying to get my 9 month old back to bed so you’re just going to get a pic of the cam card lol.
Yep. Blink and they're 23 yo adults....A 9 month old! GOD bless!!!!!
Thanks!
Now I know what my parents meant when they said they wish they could the. The clocks back to when I was just a baby/kid.Yep. Blink and they're 23 yo adults....

My oldest is about to turn 30. My youngest recent joined the USAF. He’s no longer just a big boy!
When they were small, they were a tough job but the best job to ever have.

Taking my 69 340 to the Dyno in a couple of months.
Just curious what everyone thinks since we are on the topic.
TRW flat tops 10.5:1
X heads
RPM Air Gap
Holley fuel pump
Holley 670 DP
TTI Headers
FBO Ignition
This is just going to be an engine dyno. Car is not ready yet.
I’ll post Dyno sheet when it’s done to see how close everyone is.
Thanks in advance.
No offence, but ditch the hydraulic cam. Call a Mopar grinder like Howard's, Delta, Oregon cam grinding ect. Secondly pay attention to lift at .200". Chrysler heads are limited in cfm if your using oem castings. Save your $ and get a stick ground for maximum velocity. Look up the La head cfm reports on this site you'll get the picture.I have 1971dodge demon 340 that is .30 over flat top kyb pistons ,comp cams 268/280 ,750 double pumper, edelbrock rpm air gap port matched and headers 3.73 gears and with automatic. My engine builder said it might make 400hp but he said it's hard to get that out of 340 unless you stroke it. Why is this so hard.
Is the casting modified by Allstate? Dig the removable air bleeds!My 416 is getting 550 tunnel ram carbs from Allstate carbs. More tunable.
Looking forward to those.

Custom-built Holley 550 cfm carburetors. For Hemi motors, Inline tunnel ram, Jet boats, etc
550 HOLLEY TUNNEL RAM CARBURETORS. This is an unique set of custom 550 cfm mechanical secondary. These are only available here. These highly developed carbs are also the hottest set of tunnel ram carbs to date. Because of the design and claibrations the quick throttle response will throw you into your seat. Also they have a Very clean idle quality. YES they are MECHANICAL SECONDARY carbs. They are similar to the Holley 9776. Choose your finish from the drop-down menu. ACFI Polished finish as shown or the classic Holley Gold. All Non-stick gaskets and .110 adjustable needle and seats. Also featured in this set of carburetors are custom secondary metering plates. Because of this the secondary main jets are removable as well as the primary. Thus making these more tunable to your engine.
It took about a week and a half to ship once I ordered them. Two guys work there Jim and Jarred. When I called to order them they told me that they would have to build them before shipping.
Looking forward to seeing how they do this summer.
I don't, but I will call them tomorrow to find out. I had them shipped to my builder and have not laid my hands on them yet.Do you happen to know the venturi and throttle blade diameters of your carbs??
I don't, but I will call them tomorrow to find out. I had them shipped to my builder and have not laid my hands on them yet.
I'll update this information once I can.
I'll ask them. I have been running 660's for the last few years, installed annular boosters, and a lot of jet changes to get them somewhat tuned for this altitude. I wanted something better without going to fi. I hope these are the ticket.I think it will be interesting to see the sizing. I'm not sure if they get that flow rating by those sizes or if the are using a straight leg booster to get that flow number.
Initial tuning on TR carbs is enough work. Tuning for altitude is a whole other game. I've tuned for about 4500 feet coming from sea level. I was shocked at what I had to do. I can't imagine tuning to 8000 or 9000 feet.I'll ask them. I have been running 660's for the last few years, installed annular boosters, and a lot of jet changes to get them somewhat tuned for this altitude. I wanted something better without going to fi. I hope these are the ticket.

I talked to a carb builder in Texas a month or two ago. Actually his wife answered the phone but couldn’t answer many questions. I’m not sure if it was his shop or not. I’ll look it up again to find out.Have you Spoken to Steve Taylor? Carb builder in Tx. Ran Bandemere successfully.
