    Need help with Propane dynamic compression ratio

    Thanks for the tip about different countries LPG and engine specs. I do have two complete Impco 425 systems that I can combine on my engine. However, I was going to start with one because I already have an Edelbrock Performer manifold. Mining, I have been looking for that book for less than...

    Need help with Propane dynamic compression ratio

    Thanks for the reply. My plan with the timing was to set the dist to: 30 degrees total, base, vacuum and centrifugal combined. All in at 2500 RPM. From that I am going to get a wide-band O2 monitor and knock sensor to fine tune the air/fuel and timing. That being said, despite searching...

    Yes, I have talked to three of the largest vendors. The cam profile that I want to use maintains a somewhat higher dynamic compression that most builds that they see. They have not said that it would not work, just that they don not have enough experience to give an educated opinion.

    Need help with Propane dynamic compression ratio

    I am building a Chevy 454 bored .060 over for a street driven pickup intended to be a daily driver, with no towing or real hauling ever. I have done all of the machine work and have ordered parts with the exception of the pistons. I have question about what compression that I should shoot for...
