    I am running a 425/409 in my coupe with a Z11 cam. It ain't no boat anchor for sure.... In fact it hauls.
    Love the sound from them too, must be the shape of the combustion chamber that does it.

    I can deliver to Louisville if your interested, I think I can save my money and build the small blocks much cheaper. I would not sleep well if I blew a "W" motor, and had to think about praying for a spare block or head.

    Lets talk - not scrap price. If you want scrap price, let me smash a hole in the block first.

    I think these belong in a museum, they are neat to look at.

    I agree..................In their day they were pretty impressive, but there is little discussion after 1964 when the Mercury Comets came out with 427 SHOC's and MAX WEDGE 426's, and the 426 HEMI's. I am a Chevy guy, but we did not have much to offer in the mid sixties until the 396 & 427's finally came around. The the W's were regulated to street use and barns.

    back in the early 60,s the 409,s and pont. 421,s were the cars to beat there was a black 63 chevy called mr.clean and a 64 chevy 2 dr sedan called spur,s 9 both very fast cars most fast mopar were company back cars but one 62 dodge a guy name eddie hado had called the jersery saker i think it had a 413 in it that was just fast all i,m saying is at that time the 09,s were street legends and so many other too . but if you wanted a car that looked cool sounded cool,and fast you saved your pennys and saved your dimes and got your self a 409

    We, the three brothers just sold (deposited) my deceased brothers SS 64 Convertible 409 to a Hamb'er in California. It has sat so long I almost cried when I saw it. There ain't much left but some memories and a driveline matching numbers.

    IT, was what got me started on streetrods, fast cars riding the rear seat with that 409 burbling.. THE rear mag passed us once in town, tore the middle right out of it.. LOTS of torque and a heavy body makes for lots of broken parts.

    I build rods at times, I'm mostly a swap and paint kinda guy. I felt this old impala was beyond me and my skills. I remember most, that old car eating starters, flywheels and running like stink with that powerglide.. NO other powerglide I ever had ran like that.. well the camaro with the vega torque convertor took off like that, but didn't keep them wheels spinning like I remember the impala did.

    Hey David, I knew a man down your way some time back named Wallace Reagan who was into 409's. He was in the Rocky Face, Tunnel Hill, Dalton area, have you heard of him. Had quite a collection of stuff!

    If you like it. Then it's cool. Any engine ever made can be picked apart by the in the know crowd. If your not using an engine for your Hot Rod because it's heavy, then maybe the Billet guys are for you. Hot rodding is all about whats cool to the owner.

    This weekend I was at an auction and I saw a 409 that coded out to be a 64 340 horse passenger car 4 barrel manual trans. The bare block alone sold for more than 2k. Sounds like alot, but then again if you need that specific # block where else are you gonna find one.

    With edelbrock's new head, plus newly available lightweight pistons from JE, and 4340 bbc rods that swap right in, a 409 is a viable alternative for a 4-600hp engine in a period car. They make 500 cid stroker kits as well. Headers and intakes are the hard part.

    The October issue of Hot Rod magazine (just bought it last week on the news stand) has an article on a 409 buildup. it is definately worth the read. They built a reliable 409 engine with upgraded components available today and it got 466 HP and 461 Ls of torque --- and that was starting with a truck engine, as I recall. I drug one of those truck 409s home a couple summers ago, and now I've got some inspiration for building it right!

    Cooling Problems - Simple - Measure Temp of coolant in and out of radiator.
    I see your fan has no shroud - that is bad. You would not be pulling enought air thru the radiator to transfer heat to air.

    Half of blade needs to be inside of shroud.

    Delta T - Temp Drop across radiator, if very little, then no air flow. If Temp Drop is too great, no coolant flow. You need a thermostat as well to regulate the flow.

    We have a 4 core rad, mechanical AND electric fans, shroud too (it was off in this pic). We also drilled out the thermostat for more flow. Car runs minimum 210 at all times.

    Most times overlooked. Timing a little too high, and carb(s) lean....

    Verify:
    Timing - Good Note from CNC Dude, verify the TDC is correct. What compression ratio are you running. Fuel Quality - My 12:1 292" ran hot until I put good fuel in it. Then I could set the timing. While on the Premium fuel, i could turn the distributor a ridiculous amount and the engine speed did not change, most likely preignition.

    Temp Gauge Accuracy - Verify it is reading correctly. Add another near outlet of Radiator if threaded.

    Measure temps in and out of radiator. What is the temp drop you are seeing. Recovery tank - keep's radiator full. Too much flow in cooling system is not always good. Drilling out stat is mistake. Use a Brass Robert Shaw stat (3 bar) not junk stat or flow restrictor, those are junk on the street.

    Cooling System Pressure - Verify Cooling system pressure - Higher Pressure is better. 7 PSI too low, could cause localized boiling of coolant. Use a recovery cap with the recovery tank.
     
  30. The JE pistons you read about in Hot Rod Magazine were 814 grams. A factory/TRW weighs 844 gram. I have made them here
    @ CP Pistons and when I worked at Ross Pistons in the
    660 gram range if you want actual liter pistons. Also
    Edelbrock makes a brand new Performer RPM style 2 plane 2 4bbl that is much better than the original. Also
    if you use light tension rings (like the ones that come in
    new factory hot rods) there is much more performance to be had. The old "D wall" 1/16 & 5/64 rings do nothing but wear out the cylinder walls thats why all the 50's-70's engines end up with big ring ridges. The only down fall to these engines I see, especially the 409
    is the price of the blocks, 2500-5000. Bill Mitchell has said he believes he can cut an aluminum tall deck rat
    block down to the 409 (9.600) with the right deck angle
    and bolt pattern for the 409 heads.
