Should get over 400 hp, even with low CR |

Unless your lifters are getting the pressure they need (you arn't using those variable bleed off ones are you?)I'd say the cam is way out. The cam needs to be matched to your CR. Why don't you spend about $30 for desk-top dyno and run your info through it. I havn't tried it, but it's a well thought of piece of software, and I intend to purchase it some day. I called Crane when I did my engine and they put my numbers through their program. They predicted 480 Hp with a 9.5 CR and a fairly mild solid lifter cam. I think that is optomistic as it calls for "perfect" tuning which I doubt I have, but by the way the car runs, I know it's well up there. By the way, this dyno testing you had done.....was that a wheel dyno with the engine in the car, or a engine dyno. You'd be surprised how much you lose, especially with an automatic tranny. As for getting a CR above 10, well.....you will get away with it with Al heads, but not with "FE" heads (a pun here). Today's "high test" just isn't what was available in the 60's when these motors were available with such high CRs. And now comes the critiques of my posting............... |
