New to 409’s.

With 2.19 intake and 1.72 exhaust valves,bowl and minor port work,and a good valve job,333's can easiily support 500 hp at 10-10.5 compression.That's been proven many times.What are your goals for this package?Are you considering stroking it
?

I don’t have goals for this at this point. I have always wanted a 409. My Dad had on in a 55 and then in a 37 Fiat. Ran high 9’s back in the 60’s. So I have always been a real fan of the 409. I just think the are cool.

I have 2 cars it can go into. I have my 56 wagon and my 55 Chevy. The 55 is getting a straight axle here this fall and I am doing a Gasser. It’s has a strong full roller aluminum head 383 SBC. Car runs low 12’s. So I consider putting it in that with fender wall heads. I could also put it in my 56 wagon. It would just be a mild build for that ring bearing and some port work. Either way I want iron heads vs aluminum for the nostalgic look!!!

KB makes a piston[Icon]that is availeable in .038,.048,ect that will let you use your stock rods and put yiur compression at just under 10 - 1.A cam with around 224 in.at .050 intake,230 ex.,on a 110 lobe seperation,a single 4bbl...[Edelbro9ck performer rpm]intake,750 carb.and above head work will put you just over 1 horse per inch and more torque than you kn ow what to do with.
