I have one of those intakes thinking of putting webbers or something like that on it or mayb even some sort of EFI.

Thanks Allen, My machine shop guy gave me there number yesterday, thanks for the numbers I will call them. Jeff

Hey guys, I am having trouble getting a set of +.100 longer valves with an 11/32 stem I have found that a BBC stock valve will work fine but am having trouble with the exhaust. Manley will make me a set but surely there is a production valve already out there that may work. Anyone else ran...

JimsSS409 thanks for all the info that is good to know. Right now I am looking at a comp grind which is 236@50 with 560 lift and also and isky grind which is 250@50 with 560 lift both have a 108 lobe center. From what you say the first cam might be a better choice. One other question did you...

236@50 is around 282 advertised that is not very much duration for a big block, what profiles are some of you guys running?

Guys, I need some help making some decsions on what cam I am going to use. I went through the old threads and there were a few ideas but here goes. My motor is a 340hp car motor .30 Ross 10.5:1 forged pistons, I will be using the 817 heads however we are doing some work to the heads. Bowl...

Thanks for the info guys. I am not building a race car but I am building a hot rod (1934 ford) and it might see some 1320 passes. My motor is a 340hp 409 at the machine shop getting bored so I am needing to order pistons. Aubrey those pistons and rods looked great I will try to give you a...

Hey Guys, This may have been asked before but what is the solution for the 409's weak rod problem? Does anyone make a better rod for a stock 409? Or does anyone make a piston with a corrected pin heigth to accept the 6.135 BBC rod with a stock 409 crank? I would like to use an H beam style...

I too have this same block #814 with CFD stamped on it, also it has an X on the front. My block is a QG which is a 340HP and it also had #817 heads so it definitely was a 340HP, but what exactly does the CFD mean. I found this motor in a 57 Chevy in an old junkyard. Jeff

29 Motor looks awesome in that "A". Are those the Sanderson headers on there? I am still not sure what to do about headers on my engine. I might just use the 340hp manifolds, they fit so good and do not see any steering problems with them, plus I am going to run a full hood. I have not...

Hey Guys, My frame is done and body stripped and ready for new floors and firewall but had to drop the 09' in to see how it would look. The body is not on their correctly but could not wait to see how the 409 would look. That is not the motor I am using that is a truck 348 I picked up at a...

Thanks for the reply guys, sorry I did not have any time today to pull the valve covers, I had to go the Atlanta Motor Speedway and watch the race today! Ed409 made a good point that those blocks are thick walled and can easily be bored to 409 specs. Is the block the same as a 409 just a...

Ed, I have heard that too, I am curious to know that for sure. Thanks for the reply. Jeff

Hey Guys, I recently purchased a complete 409 motor but after further inspection it happens to be a 348 block#3857655. What puzzles me about it that it has a 409 oil pan with dipstick on the right and also is has a 305 hp highrise 4bl 348 intake on it. The block has an X cast on the front...

I have an Offenhauser 4x2 setup for Strombergs, Speedway motors sells and adapter for the 3 hole Stromberg to 4 hole Rochester 2G. I am thinking of running this on my 409 which when finished will have a 427 crank and be going in a 34 Ford Coupe.
