    2 x 4 intakes

    Ok, I have both intakes, the one I select will be on a 10:1 compression ratio 427 CID 409 with 817 heads with minor porting and 2:19/1:72 valves. I like the look of the Offy but dont want to sacrifice performance thanks for now!

    2 x 4 intakes

    Hi everyone, any ideas how a high rise offy 2 x 4 intake stacks up to the edelbrock 5408 2 x 4 intake in terms of performance? Any actual dyno comparisons out there? Thanks

    All sound advice I know I am dreaming, safe wall thickness to me would be .125-.150 if it flies this would be a 9 1/4-9 3/4 to 1 compression motor with a mild hydraulic cam. Sonic check takes place next week I will post results.

    I have a 409 crankshaft and found a set of 340 HP 409 standard pistons if the 962 casting 348 truck block sonic checks to go to 4.312 then I would have a motor to make my project car mobile while I slowly move forward on the long term motor, a 409 truck block .060 over 4" crank H-beam rods...

    Thanks for fast responses I will post results from the sonic test. I figured too good to be true but a reliable source says he has done it but did not back up his claim with sonic test numbers. Much appreciated!
