Regrind the cam with less than .500 lift and 210 degree get good power and only pay for the regrind

Dyno tests and engine output data needs to include average power not only peak (area under the curve). As well as engine weight, physical engine size, average fuel usage under different loads, octane requirements and other data. Too much weight is given to peak numbers and output per/CID...

I had an Offenhauser 360 degree single plane on a mild 318 for many years. I was great, I replaced it with with an Edlebrock Performer after I did some work to the engine because I had no clue or review of the Offy and thought a dual plane night be an improvement. No notable difference. The Offy...

Enough to climb a fairly steep grade without downshifting

Flush the radiator before spending.

Let them "experiment"sit back and laugh, critique, take in, turn off, its up to you.

Take this as a learning experience nothing else, stop with the 'should have used'

Backfires are ignition, coil overheating

Examples may or tend to be exaggerations, however they can also be real world numbers.

Save yourself from yourself and save 50 plus cents /gallon run some 87 oct and drive it and enjoy.

They tend to migrate all over the US from coast to coast.

A car coming from a "rust free state" does not mean its rust free, and a car from a "rust' state does not mean its rusted. These are 50plus year old car made of steel, rust is rust. In 50 years any car will be subjected to a variety of conditions, evaluate it for what it is.

5.9 and never have to listen for the flat tappet "tick" nightmare. Count the number of posts for wiped cams.

Small amount of grinding test fitting the head/manifold with Fel pro gaskets no problem.

IMO any gain using a 340 driver side manifold would be offset a lot because of the wicked bend connection needed on the outlet (narrow early A vs wider chassis late A) I don't think that manifold shootout test took that into account.

Rhoads lifters made in the USA. More low end, more vacuum at idle, pumps up fully about 3000. IF you like the sound of solids at idle these are it. Most choose a cam too big for there "street strip" car anyway. If you like a choppy cruise night idle not for you. Poor man's VVT, or a practical...

Your engine needs cold air, the test has no control over temperature. Anything less than a cold air setup is losing power. Even chassis dyno tests have the hood open, not real world.

Your articulate post is going to ruffle lots of feathers here. Thanks for sharing real world experience.

Get any one of those 3 cams you picked and you can listen to the "rump rump" at cruise night with the other posers, then on the way home get passed by a Prius.

Find a cam with no more than [email protected] intake. Maybe a replacement 360 2 bbl or similar. If you go roughly 10 degrees more duration you won't lose bottom end power.

Do you offer any 318 or 5.2 crates? If not any plans for lesser HP engines?

Are the seller, the mechanic and the machinist related?

Carb CFM in question? Put a vacuum gauge on the intake run the hose so you can see while driving at Wide Open Throttle reading should be almost Zero.

If its really old I wouldn't use it

Leave them be. They are a quality product unlike a lot of crap being sold today. It MAY be possible to gain a few HP on the top end, but lose MUCH more on the bottom. Overall you car will get there faster with Rhodes lifters. Biggest complaint is noise, which sounds like solids and means the...

Can't play your youtube? but if its a no noise when idle or decelerating, maybe an exhaust manifold leak.

Run it around and let it rip with a quart of Marvel Mystery oil. New lifters are next if you can get any quality ones.

If your engine is nice and clean with no built up varnish in the lifter bores, you can use a magnet stick thru the heads and pick them out.

I would look for a 5.9 and use it will the factory F.I. setup, instead of expensive machining and parts for the 340 spend a little time and integrate the electrionics into the truck.
