I had similar results. In the mid 70" I ran a 70 340 4 speed Duster with the 284/484 installed 4 degrees advanced. 4.30 gears 28" slicks, Holley 780 and Mallory dual point ignition and some Hedman headers. At Tampa drags which was said to be 66' short it ran 12.97. At Twin City Dragstrip it ran...

You can call them and they can tell you if they can be fly cut. But first make sure the cam is installed and the C-line is correct.

I think it would be worth looking into the possibility of cutting deeper valve reliefs than starting over.

You need a clearance of .080 intake and .100 on the exhaust. No way your going to do it with head gaskets. You need to fly cut the pistons. If you have enough material.

Man that is a lot of cam. What are you planning to do with this car? Street? Race only?

What cam is it? Rocker ratio?

I've used the two piece pans. Unless it is under your intake, I don't think that is your problem. Are you using paper gaskets on the intake? Test fit the intake on the heads. It may be that the heads are cut or intake and that is your leak.

Hey Rob, is that the SS Chevelle that was in your yard years ago?

Which Thumpr cam is it?

Check here 440 Source makes them. Bearings from www.440 Source.com

Pretty neat to see the valve rotating after the valve is on the seat. ( towards the end)

Pretty good video here showing what it looks like.

Weight of the valve components and mostly worn out springs are the cause of float. Since the intake weighs more, than yes it is the one that will float first.

Do you realize this thread is over 10 years old! That 16 year old young gun is now 26!

Yup your right thread is 4 years old. And I'll trade you 1850's for 4424's all day long.

10-4, that is the only way I know to do it. It gets to be kind of a guessing game when you try and figure out is it a .474 lift or .484 lift cam.

I haven't had much luck I D ing Purple shafts in the past.

Mopar part numbers are usually 7 numbers long.

After years of being driver/engineer we deal with Critical Velocity in fire hose sizes, as well as the Laminar flow of water. For us the concern was the nominal amount (GPM) of water that we could flow through a given hose size before the efficiency went away. This is to say I could increase the...

I agree, The same motor with a dominator Team G vs a Indy intake on max wedge ported 452's and the car slowed down 2- 10's. At least this was my experience. I have always liked the Team g.

I ran the 484 cam in my 70 340 4sd. Duster. Installed it at 104 ran a Mallory unilite that was 20 degrees in at 2000 rpm and initial @ 18 . LD-340 intake 700 DP 3.91 gears. Performed very well and I never had to retune. Just had to keep replacing the rear tires!

Well it's kinda of hard to comment without an explanation? By the picture it is hard to tell what happened. Did the rotating of the crank/rods make those marks? When your tittle said carnage I expected broke rods or windowed the block.

I can't get it to work?

Sounds like a lifter noise the way your talking.

Hey I understood what you were saying. I guess us Ratards tink alik.

If you plug it off you will have to run a vented gas cap.

Because to maintain the proper geometry your rocker are adjuster should have 2-3 threads exposed below the rocker arm. If you cut the heads the old pushrods should be to long unless there was to much of the adjuster showing before the milling?

Years ago I bought a set of max wedge ported 452's from Dan Dvorak. The heads were milled so much that they "felt" fragile to me. But they worked and had pretty good flow numbers. The open chamber wasn't eliminated but there wasn't much lip left.

If you want a street-able set up I too like Bob stated run 2 600 1850 style vac secondary carbs. I have street drove 340's to 426's over the years and the 600 vac secondary carbs are much more user friendly.

Me and Moper both have said the same thing on the push rod length. Yes you will need custom/shorter pushrods. And when you take that much off the heads I would think you would plan on Roller rockers also.
